Background: Coleus forskohlii (Lamiaceae) cultivates imperishably over the tropical and subtropical regions of Asia; extracts from the roots and aerial parts of C. forskohlii are widely employed for the therapy of respiratory disorders, gastro-intestinal disturbance, heart diseases, and central nervous system disorders. The morphologies and structures of trichomes from C. forskohlii, as well as phytochemicals they secrete in China-origin plants are poorly unstated. Objectives: This study was intended to characterize the morphology and structure of trichomes and the profile of their secretory materials. Materials and Methods: To characterize the morphology and structure of trichomes, which happen on the vegetative and reproductive organs of C. forskohlii, it was employed light microscopy and scanning electron microscopy. The chemical qualities of volatile compounds from Glandular trichomes (GTs) of C. forskohlii were also studied using gas chromatography mass spectrometry (GC-MS) and histochemical reactions. Results: Four morphologically distinct trichomes, i.e., non GTs, peltate GTs, Type 1 and 2 capitate GTs, were categorized. Histochemical study naked the presence of polyphenols, flavonoids, lipids, and terpenes in the GTs. Essential oils, isolated from mature leaves by hydro-distillation, were investigated by GC-MS and 41 compounds were acknowledged with oxygen-containing sesquiterpenes and monoterpenes as the major compounds. Conclusion: Secretory materials of GTs attained by surface extraction also indicated the precise features in the China-origin samples.
