墓头回挥发油化学成分的研究

墓头回也叫箭头风,为败酱科植物异叶败酱Patrinia Heterophylla Bge.]和糙叶败酱PatriniuScabra Bge.]的根,能治伤寒、温疟,妇女崩中,赤白带下,跌打损伤等疾病,对艾氏癌细胞有抑制及伤害作用。墓头回挥发油的化学成分尚未见报道。本文采用毛细管气相色谱-质谱法对墓头回挥发油的化学成分进行了研究。色谱分离出50多个组分,质谱确定了其中30个组分的化学成分,占总色谱流出峰面积的56.32％。此外还有10个结构尚未完全确定的倍半萜烯,占色谱总流出峰面积的8.50％;3个倍半萜烯醇,占色谱总流出峰面积的4.71％;2

Studies on Chemical Composition of Volatile Oil of Patrinia Heterophylta Bge.

In this paper, the volatile oil of Patrinia heterophylla Bge. was obtained by the simultaneous steam distillation-solvent extraction, which was carried out in the device designed in our lab. The yield of the oil was 0. 63%. Its chemical composition was studied by capillary gas chromatography-mass spectrometry. Over 50 components were separated, of which 30 compounds composing 56. 32% of the oil were identified. The major component, isovaleric acid, was separated by distillation under reduced pressure and identified by MS, IR and NMR.
