Analysis of Phenylethanoid Glycosides and Flavonoid Glycosides from
Objective: To investigate the chemical constituents of Scutellaria galericulata. Method: The herb of S.galericulata was crushed and then extracted with 95% ethanol.The extracts were combined and concentrated under reduced pressure.The extracts were dispersed in water and respectively extracted with petroleum ether
ethyl acetate
chloroform and n-butanol to get petroleum ether fraction
ethyl acetate fraction
chloroform fraction and n-butanolfraction.Ethyl acetate fraction were separated and purified by silica gel column chromatography
Sephadex LH-20 and HPTLC.The structures of the glycosides compounds were identified by their physico-chemical properties and spectral data. Result: Eleven compounds were isolated and purified as:isocrenatoside (1)
osmanthuside B6 (2)
eutigoide A (3)
plantainoside C (4)
calceorioside B (5)
isomartynoside (6)
verbascoside (7)
acteoside (8)
desrhamnosyl acteoside (9)
5
7-dihydroxy-8
2'-dimethoxyflavone-7-O-β-D-glucopyranoside (10)
and apigenin-7-O-rhamnoside (11). Conclusion: Compounds 1-4 and 7-11 were isolated from S.galericulata for the first time
and the literature review showed that plantainoside C
apigenin-7-O-rhamnoside and other compounds had anti-inflammatory and antioxidant activities
providing a good reference for further studies onpharmacodynamic material basis and the development and utilization of S.galericulata.
