摘要:采用溶剂结晶法从松针聚戊烯醇生产过程得到的副产品中分离精制松针甾醇,利用气相色谱-质谱联用技术对其化学成分进行了分析。结果表明,从精制松针甾醇中共分离鉴定出6种植物甾醇,分别是β-谷甾醇89.32%、豆甾烷醇5.07%、菜油甾醇3.90%、豆甾-7-烯-3-醇0.42%、麦角甾烷醇0.35%、豆甾-5,24(28)-双烯-3β-醇0.25%,6种植物甾醇含量之和占总量的99.31%。
The crude extract of pine-needles phytosterols, which was the by-product of polyprenols production from pine needles of Pinus massoniana Lamb., was purified by solvent crystallization, and was analyzed by gas chromatography-mass spectrometry. The results showed that from the purified phytosterols of pine needles six kinds of phytosterols were isolated and identified, which were β-sitosterol 89.32 % , stigmastanol 5.07 % , campesterol 3.90 % , stigrnast-7-en-3-ol 0.42 % , ergostanol 0.35 % , stigmast-5,24 (28)-dien-3-ol 0.25 %, the identified compounds accounted for 99.31% of total content.
