南竹过热水萃取物成分的GC/MS分析

Determination of Chemical Components of Phyllostachys heterocycla var.pubescen Superheated Bapour Extractives by GC/MS

以新鲜南竹为原料,采用工业可利用的竹片浸提工艺进行过热水萃取,然后利用气相色谱/质谱(GC/MS)联用技术对萃取物成分进行分析.结果表明:在新鲜南竹片过热水萃取物GC/MS分析中,共分离出36个峰,鉴定出25个化合物,占总峰面积的97.35%.主要成分为二十七烷(cas)(26.2%)、14-á-H-pregna(15.71%)、2,6,10-甲基-十四烷(15.55%)、甲基-9,10-二氟次甲基-9-十八碳二烯酸(12.84%)、1,2-邻苯二甲酸二丁基酯(8.93%)、1,2-邻苯二甲酸,双2-甲丙酯(2.65%)、1-五十七醇(1.88%)、isochiapinb(1.88%)、10-甲氧基-nb-à-甲基二十九醇(1.63%)等.南竹过热水萃取物中绝大部分成分具有医药作用,并含有香料.

In the paper, researchers adopt the south fresh bamboo （Phyllostachys. heterocycla var. pubescen） as raw materials. First, bamboo sheet is extracted on the hot water; adopt bamboo stretch soak technology of industrial available. And then, to analysis the extract components researchers use gas chromatography/mass spectrometry （GC/MS） technology in conjunction. Relative content of each component was determined by area normalization. 25 compounds representing 97.35% of the extractives were identified. The most abundant constituents were beptacosane （cas） （26.2 % ）, 14-a-H-pregna （15. 71 % ）, Tetradecane, 2,6,10-trimethyl- （ 15.55 % ）, methyl 9, 10-difluoromethylene-9-octadecenoate （ 12. 84 %）, 1,2-benzenedicarboxylic acid, dibutyl ester （cas） （8. 93 % ）, 1, 2- benzenedicarboxylic acid, bis （ 2-methylpropyl ） ester （cas） （ 2. 65 % ）, 1-heptatriacotanol （ 1. 88 %）, isochiapin b （ 1. 88 % ）, 10- methoxy-nb-a-methylcorynantheol（1.63%） and so on. The results show those South bamboos extracted in hot water over most of the ingredients have medical function, and contain the spices. The paper provides a scientific basis for excavate south bamboo active ingredients, and explores their higher economic value.
