从中药路路通乙醇提取物中分得八个化合物 ,经光谱解析、相关化合物光谱对照及X 射线衍射确定其化学结构。其中化合物 4鉴定为一新化合物 ,命名为 3α 乙酰氧基 2 5 羟基 齐墩果酸 ,化合物 3为首次从天然产物中分得 ,命名为 3 酮基 12α 羟基 齐墩果 2 8,13β 内酯
Eight compounds were extracted from the ethanol extract of Luantong, and their chemical structures were determined by spectral analysis, spectral correlation of related compounds and X-ray diffraction. Among them, compound 4 was identified as a new compound named 3α-acetoxy 25 hydroxy-oleoic acid. Compound 3 was firstly obtained from natural products and named as 3-keto 12α hydroxy-2,13β-lactone.
