[Studies on chemical constituents in dried buds of Lonicera similis Hemsl].

To study the chemical constituents in the dried buds of Lonicera similis.Chromatography and spectral analysis were used to isolate and elucidate the constituents.Nine compounds were isolated from the dried buds of L. similis, and identified as caffeic acid; 3,5-O-dicaffeoylquinic acid; chlorogenic acid; palmitic acid; luteolin; quercetin; beta-sitosterol; nonacosanol; nonacosane.All the compounds were isolated from the plant for the first time.
