Objective To study the chemical constituents from Lepidogrammitis drymoglossoides. Methods The constituents were isolated and purified by various column chromatographies, and their structures were identified on the basis of chemical evidences and spectroscopic analysis including MS, 1H-NMR, and 13C-NMR. Results Fourteen compounds were isolated and identified as β-ecdysterone (1), physcion (2), emodin (3), umbelliferone (4), scoparone (5), aesculetin (6), caffeic acid (7), chlorogenic acid (8), protocatechuic acid (9), pyrocatechualdehyde (10), gallic acid (11), 4-hydroxybenzoic acid methyl ester (12), docosanyl tetracosanoate (13), and hexadecanoic acid (14). Conclusion Compounds 3—5, 8, and 11—13 are isolated from the plants of genus Lepidogrammitis Ching for the first time.
