齿瓣石斛全草用甲醇进行提取,甲醇提取物加水后,用乙酸乙酯萃取。乙酸乙酯部分进行硅胶柱层析,石油醚洗脱部分得其脂溶性成分,然后通过气相色谱-质谱(GC-MS)联用技术,对其中的化学成分进行分析鉴定。通过计算机检索,鉴定了其中的48个化合物,占脂溶性成分总量的95.59%,主要为泪柏醇、烷烃和芳香族物质。含量大大成分为泪柏醇(31.34%)、正二十三烷(17.77%)、正二十二烷(6.77%)、正二十一烷(5.43%)、正二十烷(5.21%)、正十九烷(4.73%)、正十八烷(2.99%)和6-二特丁基-4-甲基苯酚(1.05%)等。
Dendrobium petal whole plant with methanol extraction, methanol extract with water, extracted with ethyl acetate. The ethyl acetate fraction was subjected to silica gel column chromatography. The fractions were eluted with petroleum ether to obtain the lipophilic components. The chemical constituents were identified by gas chromatography-mass spectrometry (GC-MS). Forty eight compounds were identified by computer, accounting for 95.59% of the total liposoluble components, mainly Telazol, alkanes and aromatics. The major components were Terebrand alcohol (31.34%), n-tricosane (17.77%), n-docosane (6.77%), n-eicosane (5.43% , N-nonadecane (4.73%), n-octadecane (2.99%) and 6-dibutyl-4-methylphenol (1.05%).
