摘要
从紫红獐牙菜(Swertia punicea Hemsl.)中分离到5个单萜环烯醚甙。鉴定为苦龙胆甙(amarogentin)(Ⅰ)和它的新异构体,命名为苦龙胆甙B(amarogentin B)(Ⅱ)以及龙胆苦甙(gentiopicroside)(Ⅲ),獐牙菜甙(sweroside)(Ⅳ)和獐牙菜苦甙(swertiamarin)(Ⅴ)。
Five secoiridoid glycosides were isolated from Swertia punicea Hemsl. which identified as a new glycoside amarogentin B ( Ⅱ ) , together with four known compounds amarogentin (Ⅰ), gentiopicroside (Ⅲ), sweroside (Ⅳ) and swertiamarin (Ⅴ) by means of spectral and chemical analyses.
