Abstract:
Objective: To search for the bioactive compounds from the vine of Lonicera dasystyla. Methods: The compounds were isolated and purified by column chromatography on silica gel, sephadex LH-20 gel, and ODS, and their structures were elucidated on the basis of spectroscopic analysis, such as MS, NMR, etc. Results: Nine compounds were isolated from the vine of L. dasystyla. Their structures were identified as dihydrosesamin-9-O-β-D-glucopyranoside (1), isoferulic acid (2), p-methoxycoumaric acid (3), kaempferol-7-O-(2″-E-p-coumaroyl)-α-L-arabinofuranoside (4), macranthoidin B (5), loganin (6), kaempferol (7), acacetin (8), and quercetin (9). Conclusion: All of these compounds belong to four types, phenylpropanoids (1-3), flavonoids (4, 7-9), triterpenoid saponin (5), and iridoid (6). Compound 1 is a new one and compounds 5 and 6 as marker compounds exist in most of Lonicera Linn. plants, while known compounds 2-4 and 8 were isolated from Lonicera Linn. plants for the first time. The identification of these chemicals lays the foundation for searching bioactive compounds of this plant, and these compounds have great importance for chemotaxonomy of this plant.
