Chemical constituents from Phymatopteris hastate
2014
Objective To study the chemical constituents from the whole plants of Phymatopteris hastate. Methods The chemical constituents were isolated by repeated chromatography on silica gel column, ODS column, and Sephadex LH-20. Their structures were elucidated by physicochemical properties and spectral analysis. Results Fifteen compounds were isolated from methanolic extract of P. hastate and identified as kaempferol-3-O-α-L-arabinofuranosyl-7-O-α-L-rhamnopyranoside(1), caffeicacid-4-O-β-D-glucopyranoside(2), kaempferol-7-O-α-L-rhamnopyranoside(3), kaempferol-3, 7-di-O-α-L-rhamnopyranoside(4),(-)-epiafzelechin(5), kaempferol(6), quercetin(7),(24R)-24-(2-hydroxyethyl)-20-hydroxyecdysone(8), hop-22(29)-ene(9), hapan-29-ol acetate(10), 22-hydroxyhopane(11), dryocrassol(12), β-sitosterol(13), fumaric acid(14), and β-daucosterol(15). Conclusion Compounds 5—15 are isolated from the plants of Phymatopteris Pic. Serm. for the first time.
