[Study on chemical constituents in seeds of Helicia nilagirica (II)].

OBJECTIVE

To study the chemical constituents in seeds of Helicia nilagirica.

METHOD: The ethanol extract was seperated by petroleum ether, dichloromethane, n-butanol in sequence, then isolated by silica gel column chromatography. The structures were identified and elucidated by physicochemical properties and spectral analysis.

RESULT: Five compounds were isolated from the dichloromethane and n-butanol extracts, identified as p-hydroxybenzaldehyde (1), p-hydroxybenzoic acid (2), gallic acid (3), helicide (4), 4-formylpymyl-O-beta-D-glucopyranoside (5).

CONCLUSION

All the compounds except IV were isolated from the plant for the first time. The compounds I, II and III were isolated from the genus Helicia for the first time.
