Abstract: Objective To study the chemical constituents of the whole-plant of Leptodermis pilosa. Methods Silica gel MCI and Sephadex LH-20 column chromatography were used to isolate and purify the chemical constituents of L. pilosa. The structures were identified based on physicochemical properties and modern spectroscopic analysis techniques. Results Eight compounds were isolated from the ethyl acetate fraction of the 75% ethanol extract of the whole-plant of L. pilosa and identified as oleanolic acid1), 2? -hydroxyloleanolic acid2), arjungenin3), scopoletin4), methyl caffeate5), syringic acid6), salicylic acid7), and daucosterol8. Conclusion All the compounds were isolated from L. pilosa for the first time and compounds 2-7 were first isolated from genus Leptodermis.
