摘要
鸦胆子油在治疗颈癌、胃癌、肺癌等方面,已取得较好的疗效~[1,2]。本文用~1H NMR测定了该油的各组峰面积积分。为纠正最强峰C CH_2C对其两侧弱峰的干扰,作者提出一个经验公式以扣除基团重叠部分的积分值。并按文献[3]的方法,计算了鸦胆子油中每摩尔所含各功能团的个数、各功能团间的比率、酯化度、不饱和度、结合脂肪酸基平均碳数和平均分子量等。并从所测得结合脂肪酸的含量,估算出鸦胆子油中的油酸的含量,结果与文献[4]相符。
The oil of Brucea javanica ( L. ) Merr. has a better therapeutic effects for intrauterine, stomach and lungs cancer. 1H NMR determination of this oil was carried out. Using an equation of author's thumb we estimated partial peak integrations in order to correct the interference of the CCH2C strong peak to the neighbouring weak ones.
After the manner of reference [3] the amount of each functional group, ratio of quantities among various functional groups , esterification degree, unsaturation degree, average length of the saturated carbon chain , average carbon numbers in the combined fatty acids and average molecular weight per mole of oil were calculated. The analytical result showed that the amount of oleic acid in Brucea javanica (L.) Merr oil agrees with analytical result of gas chromatography.
