Title: Chemical Components in Hemsleya chensnsis (Ⅲ)
Abstract: To study the chemical constituents of Hemsleya chensnsis.Various chromatographic techniques were used to separate and purify the constituents. The spectral data (MS, NMR) were obtained for structure elucidation.Eight known triterpenoid saponins were isolated from the root of H. chensnsis. Their structures were elucidated as dihydrocucurbitacin B (1), 25-O-acetyl-dihydrocucurbitacin F (2), cucurbitacin F (3), 3-O-(6'-ethyl ester) -beta-D-glucuropyranosyl oleanolic acid-28-O-alpha-L-arabinopyranoside (4), oleanolic acid-3-(6'-methyl ester) -beta-D-glucuropyranosyl (1-3) -alpha-L-arabinopyranoside (5), oleanolic acid-28-O-beta-D-glucopyranosyl-(1-6) -beta-D-glucopyranoside (6), 3-O-(6'-methyl ester) -beta-D-glucuropyranosyl oleanolic acid-28-O-beta-D-glucopyranosyl-(1-6) -beta-D-glucopyranoside (7), 3-O-(6'-methyl ester) -beta-D-glucuropyranosyl (1-2) -beta-D-glucopyranoside-oleanolic acid-28-O-beta-D-glucopyranoside (8).All compounds except for 2 were isolated from H. chensnsis for the first time.
