Chemical constituents from Lepidogrammitis drymoglossoides / 中草药

ABSTRACT

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.
