Abstract
Objective To study the chemical constituents from the whole plants of Pteris semipinnata.Methods The chemical constituents were isolated by silica gel,sephadex LH-20,ODS,macroporous resin,MCI Gel resin and semi-preparation HPLC.Their structures were determined on the basis of NMR and MS analysis.Results Twenty compounds were isolated and identified as apigenin (1),apigenin-7-O-β-D-glucopyranoside (2),apigenin-7-O-β-D-gentiobioside (3),apigenin-7-O-β-D-glucopyranosyl-4'-O-α-L-rhamnopyranoside (4),isoviolanthin (5),luteolin (6),luteoloside (7),luteolin-7-O-β-D-gentiobioside (8),quercetin-3-O-β-D-glucopyranoside (9),kaempferol-3-O-β-D-glucopyranoside (10),rutin (11),epigallocatechin (12),pinoresinol-4-O-β-D-glucopyranoside (13),phillyrin (14),bergeninum (15),protocatechuic acid (16),trans-caffeic acid (17),gallic acid (18),β-sitosterol (19),and β-daucosterol (20).Conclusion Compounds 3,5,12,13,and 15-18 are isolated from the plants of Pteris,and 2-5,8-13,and 15-20 are isolated from this plant for the first time.
