单叶蔓荆子化学成分研究初报

A Preliminary Study on Fructus Viticis(Vitex trifolia var.simplicifolia Fruits)

对产于福建(莆田平海)海滨沙地的单叶蔓荆子的一般化学成分进行了分析,为开发利用福建沿海沙滩单叶蔓荆资源提供科学依据。结果表明:福建产单叶蔓荆子的水分、脂肪、粗蛋白及灰分含量分别为10.8%、4.05%、5.9%和3.36%,符合2005年版《中国药典》要求。其重金属元素含量Pb<0.01μg/g、As<0.1μg/g、Hg<0.01μg/g、Cd为0.02μg/g、Cu为6μg/g,达到《药用植物及制剂进出口绿色行业标准》(WM2-2001)中重金属元素限量要求。蔓荆子生药材17种氨基酸总量为3.51%(mg/100 mg),此外还检出微量γ-氨基丁酸(GABA,2.203 mg/100 g)。蔓荆子生药材中含有10种脂肪酸,以不饱和脂肪酸(69.6%)为主,主要成分包括棕榈酸(6.6%)、硬脂酸(5.4%)、油酸(22.0%)、亚油酸(46.0)及少量亚麻酸(0.8%)。

It was analysed that general chemical components of the fructus viticis （Vitex trifolia var. simplicifolia fruits）, in order to reasonablely exploit the resources of Vitex trifolia var. simplicifolia in Fujian coastal sandy lands（ Pinghai town of Putian city）. The analytic results showed that content of moisture, fat, crude protein and ash in the fructus viticis were 10.8% ,4.05% ,5.9% ,3.36% respectively, and were up to the mustard of Chinese Pharmacopoeia, while the content of heavy metal elememts Pb, As, Hg, Cd and Cu were less than 0.01 μg/g, 0.68μg/g, 0.011 μg/g , 0.02μg/g and 6μg/g respectively, that were coincided to and the hygienic standard Green Trade Standards of Importing ＆ Exporting Medicinal Plants ＆ Preparations （WM2-2001）. Total content of seventeen kinds of amino acids in the fructus viticis was 3.51% （mg/ 100mg）, and γ-amino butyric acid（GABA,2.203 mg/100g） was checked out. At least 10 kinds of fatty acid composition were analysed, main composition includes palmitic acid（ C 16：0, 6.6 % ）, stearic acid （ C 18 ： 0,5.4 % ）, oleic acid （ C18 ： 1,22.0 % ）, linoleic acid （ C18 ： 2, 46.0 % ） and linolenic acid （ C18 ： 3, 0.8 % ）, and nonsaturated fatty acids made up the majories（69.6%）.
