作者等从山椒(Xanthoxylum piperitum)的根部分离得菜油甾醇和β-谷甾醇混合物,茵芋碱,1-芝麻明,二甲醚七叶亭,γ-崖椒碱,防已素,析木兰碱,laurifoline和一新的结晶性物质。后者紫外UV_(max)~(乙醇)在218,252,292,357毫微米处,并根据红外、质谱和核磁共振光谱所测得数据,此结晶被鉴定为二甲 The authors isolated a mixture of campesterol and β-sitosterol from the root of Xanthoxylum piperitum, a combination of alchemycin, 1-sesamin, dimethyl aescin, γ-camptothecin, , laurifoline and a new crystalline substance. The latter UV at (max) ~ (ethanol) at 218,252,292,357 nm, and according to infrared, mass and nuclear magnetic resonance spectroscopy measured data, the crystal was identified as dimethyl
