[Studies on the phenolic acids from Sarcopyramis bodinieri var. delicata]

To study the chemical constituents from Sarcopyramis bodinieri var. delicata.

These compounds were isolated and purified by chromatography with silica gel column combined with Sephadex LH-20 column from high polar extracts. The structures were identified on the basis of extensive spectroscopic data analysis, and by comparison of their spectral data with those reported.

Seven compounds were isolated as 3, 3'-di-O-methylellagic acid-4'-O-alpha-L-rhamnopyranoside (I), ellagic acid (II), ferulic acid (III), isoferulic acid (IV), caffeic acid (V), 3, 4-di-hydroxybenzoic acid (VI), p-hydroxycinnamic acid (VII).

Compound I, III, VI, VII are isolated from the genus for the first time.
