| Introduction|| |
For 1,000s of years, herbal product is used for prevention and treatment of various diseases in many countries. These herbal medicines have lower toxicity with high compliance and as single components, these exhibit therapeutic effects for multiple diseases.  Therefore, herbal products have gained increasing popularity and have become a popular form of healthcare. ,
Artemisia species are genus of the family Compositae consisting of more than 350 species. Artemisia apiacea is widely distributed at wasteland and river beaches of Korea, China and Japan. A. apiacea traditionally used for treatment of dermatomycosis, jaundice, eczema, decubitus and alopecia. , The recent studies about the isolated compounds from A. apiacea show the presence of campesterol, stigmasterol, β-sitosterol, daucosterol, artemisterol, 7-methoxycoumarin, 7,8-dimethoxycoumarin, daphnetin, 7-hydroxy-8-methoxycoumarin, arteminin, artemisinin, scopoletin, protocatechualdehyde, and volatile constituents, including apicin, α-pinene and Artemisia ketone. ,,,,,,,,, Recent studies about Artemisia species showed various biological activities including antimalarial, antiviral, antitumor, antipyretic, antihemorrhagic, antioxidant, antihepatitis and anticomplementary activities. , Biological activity of A. apiacea was reported that it has hair-growth activity.  A. apiacea was found to possess the antioxidant activity and protective property in CCl 4 -intoxicated rats.  Furthermore, A. apiacea showed antiinflammation activity via nuclear factor-kB inactivation. 
The phytosterol derived from vegetable oils or wood pulp has various bioactivities.  Phytosterols, including stigmasterol, campesterol and daucosterol were detected in A. apiacea. Stigmasterol has antiosteoarthritic, neutralization of viper and cobra venom, thyroid hormone and glucose regulatory activities. ,, In recent study, it also exhibited cognitive ameliorative effects against scopolamine-induced memory impairments in mice.  Campesterol have antiangiogenic activity.  Daucosterol exhibits immunoregulatory activity and promotion activity for the proliferation of neural stem cells. ,
The natural products contained various chemical compounds such as terpenoid, flavonoid, alkaloid, saponin and phenol etc. Chemical composition of compounds was varied depending on several factors, such as plant origins, geographic area, harvest time and even storage method.  This variability can result in significant differences in pharmacological activity. Therefore, the establishing reliable and accurate analytical quality control method for natural products is necessary for evaluation of safety and efficacy.  In many approaches, high performance liquid chromatography (HPLC) is a simple and popular method for the analysis of natural products. Due to its easy operation, side suitability and high accuracy, HPLC method extensively applied to analysis of natural product over the past decades.
In this study, a simple and reliable HPLC-diode array ultraviolet/visible detector (UV/VIS) (DAD) and liquid chromatography-mass spectrometry (LC-MS) method has been established for simultaneous determination of three phytosterol compounds, campesterol, stigmasterol and daucosterol in A. apiacea [Figure 1].

| Materials and methods|| |
Artemisia apiacea samples were purchased from Kyung-Dong Market in Seoul (Korea) and were authenticated by Dr. Young Bae Seo, a professor of the College of Oriental Medicine, Daejeon University (Korea). A voucher specimen (no. CJ064M) was deposited at the Kangwon National University in Chuncheon (Korea).
Campesterol, stigmasterol and daucosterol used for standard compounds were isolated from A. apiacea by silica gel column chromatography. Structures of isolated three compounds were determined by spectroscopic methods, including nuclear magnetic resonance spectrum and compared with spectroscopic data of the literatures.
High performance liquid chromatography-grade acetonitrile (ACN) and water were purchased from J. T. Baker (USA). Trifluoroacetic acid (TFA) was purchased from DAE JUNG (Korea). Methanol and dimethyl sulfoxide (DMSO) was purchased from DAE JUNG (Korea).
Preparation of standard and sample solutions
Standard stock solution of campesterol (500 μg/mL), stigmasterol (620 μg/mL) and daucosterol (640 μg/mL) were prepared in 2% DMSO in MeOH, respectively and stored below 4ΊC. The working standard solutions were prepared by appropriate dilution of stock solutions with MeOH. These diluted working solutions were used for establishment of calibration curves.
The herb of A. apiacea sample was extracted by ultrasonication in 80% MeOH. The solvent was removed by vacuum evaporator and the residue was freeze-dried. The dried sample was dissolved in 5 mL 2% DMSO in MeOH. All sample solutions were filtered through a 0.45 μm membrane filter before HPLC analysis.
High performance liquid chromatography-diode array ultraviolet/visible detector analysis condition
The HPLC equipment used was Dionex system (Dionex, Germany) composed of a pump (LPG 3X00), an auto sampler (ACC-3000), a column oven (TCC-3000SD) and DAD-3000(RS). System control and data analyses were executed by Dionex Chromelon™ Chromatography Data System software (Dionex, Germany). HPLC analysis was conducted on Shiseido C 18 column (4.6 mm I.D. × 250 mm, 5 μm pore size).
The mobile phase was composed of 0.1% TFA aqueous solution (a) and ACN (b) at a flow rate of 1.0 mL/min. The HPLC gradient profile was as follows: 10% b at 0-5 min, 10-90% b at 5-45 min, 100% b at 45-65 min. The sample injection volume was 20 μL. Four different ultraviolet (UV) spectra (205, 254, 280 and 330 nm) were selected to determination of each standard compounds and each chromatographic peaks of compounds were confirmed by comparing their retention time and UV patterns.
Liquid chromatography-mass spectrometry analysis condition
Liquid chromatography-mass spectrometry analysis was performed on TSQ Quantum Ultra Triple Stage Quadrupole Mass Spectrometer (Thermo Fisher Scientific, Germany) equipped with electrospray ionization (ESI) ion source in positive ion mode. The chromatographic separation was achieved on Shiseido C 18 column (4.6 mm I.D. × 250 mm, 5 μm pore size) with the same elution program of HPLC-DAD analysis. The MS operating condition (positive ESI ion source) were as follows: Ion spray voltage at 4,000 V, the vaporizer temperature at 100°C, capillary temperature at 350°C, sheath gas pressure at 60 psi and aux gas pressure at 30 psi. Mass spectra were recorded in the range of m/z 250-650.
Validation of the high performance liquid chromatography method
The established HPLC method was validated according to the International Conference on Harmonization guidelines. Validation was performed in terms of linearity, precision and accuracy. ,
The standard stock solution containing three marker compounds was diluted to a series of appropriate concentrations with MeOH for the construction of calibration curves. Each diluted standard solutions were analyzed in triplicate. The calibration curves were constructed by plotting the peak areas versus the concentrations of analytes and obtained regression equations. The correlation of coefficient (R2 ) was used as measure of linearity. The limit of detection and limits of quantification (LOQ) values were determined at signal-to-noise (S/N) ratios of 3 and 10 times, respectively. The precision of developed method was estimated by inter- and intra-day variations. The relative standard deviation (RSD) (%) was considered as a measure of precision. Accuracy of the method was evaluated using a spike recovery test. The accurate amounts of mixed standard solution were added to A. apiacea sample, and then analyzed three different concentrations in triplicate, respectively. The spike recoveries were calculated by the equation;
Spike recovery (%) =
(amount found − original amount)/(amount spiked) × 100 (%).
Quantification of Artemisia apiacea samples
Twelve A. apiacea samples (A1-A12) were separated by established method for quality control and each sample was analyzed in three times. A1-A6 samples were collected from Korea and A7-A12 samples were collected from China. The content of three standard compounds in A. apiacea samples was calculated from calibration curves of standard compounds.
| Results and discussion|| |
Pharmacological effects of A. apiaceae have been attributed to the bioactivity compounds. Stigmasterol, campesterol and daucosterol were important phytosterols of A. apiaceae and considered to be responsible for therapeutic effect, such as antiosteoarthritic, cognitive ameliorative effect, antiangiogenic activity and immunoregulatory activity.
Quality control of herbal medicine could identify and quantitate variation of compounds by cultivation environment. Quantitative analysis method of A. apiaceae has not yet reported. Thus, efficient analysis method of A. apiacea need for quality control. We applied HPLC coupled to DAD technique to establish analysis method and simultaneously determined three compounds, stigmasterol, campesterol and daucosterol.
Optimization of high performance liquid chromatography-diode array ultraviolet/visible detector condition
To development of optimal analytic condition, different HPLC parameters were tested including column type, mobile phase, elution system and detection wavelength. The analytical conditions were optimized considering with resolution, baseline and elution time. In mobile phase, TFA (0.1% in water) was added to obtain the inhibition of peak tailing and improvement in peak shape. Due to differentiation in highest detection wavelength of each standard compounds, the detection wavelength was optimized at 205 nm (daucosterol) and 254 nm (campesterol and stigmasterol) [Figure 2]. Injection volume was 20 μL. All peaks of each compound were separated successfully within 65 min. HPLC chromatogram of the three standards is shown in [Figure 3]a. The identification of the each compound's peaks was performed by comparing the retention time and UV spectrum. The retention time of campesterol, stigmasterol and daucosterol were 30.61, 57.62 and 60.12 min, respectively.

Identification of standard compounds
Liquid chromatography-electrospray ionization-mass spectrometry was used to identify peaks of campesterol, stigmasterol and daucosterol obtained by HPLC-DAD analysis. MS spectra of campesterol, stigmasterol and daucosterol in positive ion mode were shown in [Figure 4]. In MS spectra, the fragments of three compounds exhibited at m/s 424 [M + Na] + for campesterol, m/z 413 [M + H] + for stigmatsterol and m/z 608 [M + Na + 9H] + for daucosterol.

Linearity, limits of detection and limits of quantification
Calibration curves were plotted for each standard compounds and relative regression coefficients (R2 ) were calculated to validate their linearity. The calibration data of the three standard compounds showed good linearity (R2 > 0.9994) in a relatively wide concentration range. The limits of detection and LOQ values of all standard compounds were in the range 0.55-7.07 μg/mL and 1.67-21.44 μg/mL, respectively [Table 1]. These results indicate that established HPLC-DAD method has good sensitivity.

Precision and accuracy
The precision of developed method was evaluated by repetitive intra- and inter-day test. Mixed standard solutions of three different concentrations were prepared and analyzed by developed HPLC method. The intra-day test was determined by analyzing each mixed solution five times within 1-day. For the inter-day test, the same mixed solutions were analyzed five times within each three successive days. The result of detected amount of each compound was calculated using the corresponding calibration curve. The Precision was expressed by the RSD values. As a result, the RSD values of the intra- and inter-day test were found to be within the ranges 0.41-2.85% and 0.91-2.93%, respectively. Accuracy of intra- and inter-day assay was ranged 96.60-109.57% and 97.24-107.24%, respectively. The results of the intra- and inter-day tests are shown in [Table 2].

To assess the accuracy of the method, the recovery test of three standard compounds was performed. The recovery of the selected standard compounds ranged from 90.16% to 104.91%, and their RSD values were < 2.59% [Table 3]. These results showed that the established method has a suitable precision and accuracy for the simultaneous determination of A. apiacea.
Artemisia apiacea sample quantitative analysis and cluster analysis
Quantitative analysis of campesterol, stigmasterol and daucosterol in twelve A. apiacea samples was performed under the optimized HPLC condition. HPLC-DAD chromatogram of A. apiacea sample is shown in [Figure 3]b. The content (μg/mg) was tabulated in [Table 4]. [Table 4] shows that campesterol was in the range of 16.74-19.53 μg/mg and was highest content among three compounds. The content ranges of stigmasterol and daucosterl were 3.49-4.74 μg/mg and 2.05-2.40 μg/mg. the content of campesterol in A1 was higher than other samples. Stigmastrol and daucosterol was abundant in A6 and A1, respectively. Contents of campesterol, stigmasterol and daucosterol are different between Korea and China.
Hierarchical cluster analysis was performed to confirm homogeneous clusters using IBM SPSS Statistics (IBM, USA) 21. Cluster difference from twelve A. apiacea was exhibited by dendrogram [Figure 5]. We found that there are three pair samples (Cluster I, II, III). Cluster I (A2, A4 and A6) was samples collected from Korea. Two of pairs, cluster II (A7, A12, A3 and A8) and III (A9, A10 and A11) were samples collected from China exclude A3 sample. The result showed that contents of compounds in A. apiacea samples are different by cultivation environment such as collection region.
