自云南西雙版納的大花哥納香莖皮的乙醇提取物中分得5個(gè)化合物,根據(jù)理化性質(zhì)和光譜分析(IR, MS,1H, 13C,NMR)0,分別鑒定為5,7,4-三羥基雙氫黃酮(Ⅰ )、10-氨基-2,4-二甲氧基菲-１-羧酸內(nèi)酰胺(Ⅱ)、胡蘿卜苷(Ⅲ)、β-谷甾醇和豆甾醇(Ⅳ,Ⅴ),其中化合物Ⅱ?yàn)樾禄衔?化合物Ⅰ為首次從該植物中分得。

Five compounds were isolated from the bark of goniothalamus griffithii Hook. f. et Thoms Their structures were identified as 5,7, 4'-trihydroxy flavanone(I),10-amino-2, 4-dimethoxy phenanthrene-1-carboxylic acid lactam(Ⅱ),daucosterol(Ⅲ),β-sitosterol(Ⅳ)and sitgmasterol(V)by physicochemical constants and spectral analysis (IR, MS, 1HNMR,13CNMR). Ⅱwas a new compound. I was obtained from this plant for the first time.
