To study the chemical composition of Opuntia dillenii Haw.
Many kinds of chromatography methods were used to separate the chemical constituents. Their structures were determined by NMR and MS spectral analysis.
A new compound, together with five known compounds, were isolated from the 80% ethanolic extract of the stems.
The new compound was identified as 4-ethoxyl-6-hydroxymethyl-alpha-pyrone. Compounds 1, 3, 4 and 5 were obtained for the first time from the genus of Opuntia, and they were: 3-O-methyl isorhamnein, 1-heptanecanol, vanillic acid, isorhamnetin-3-O-beta-D-rutinoside. Ruin was isolated from this plant for the first time.
研究仙人掌的化学成分。
采用多种色谱方法分离化学成分。通过核磁共振（NMR）和质谱（MS）光谱分析确定其结构。
从茎的80%乙醇提取物中分离出一个新化合物和五个已知化合物。
新化合物鉴定为4-乙氧基-6-羟甲基-α-吡喃酮。化合物1、3、4和5首次从仙人掌属植物中获得，它们分别是：3-O-甲基异鼠李素、1-庚醇、香草酸、异鼠李素-3-O-β-D-芸香糖苷。芦丁首次从该植物中分离得到。
