中国特有植物金钱槭种子化学成分的研究

STUDY ON CHEMICAL CONSTITUENTS IN SEEDS OF DIPTERONIA SINENSIS OLIV. NATIVE TO CHINA

采用气相色谱，液相色谱，氨基酸高速自动分析仪，以及化学分析的方法，对中国特有植物金钱槭（ＤｉｐｔｅｒｏｎｉａｓｉｎｅｎｓｉＯｌｉｖ．）种子的化学成分进行了研究。首次报道金钱槭种子含油率２９．１４％。油的理化常数：折光率１．４７３２（２０℃），皂化值１７８；７０，酸值６．９０。油的脂肪酸组成（％）：油酸３６．７，亚油酸２４．２，芥酸１７．８，花生油酸７．２．亚麻酸２．８，棕榈酸６．７，花生酸３．０，硬脂酸１．５，以及微量的棕榈油酸、十六碳二烯酸，山酸和１种未鉴定酸。种子含蛋白质２９．１６％，含游离氨基酸０．４２５％，含水解氨基酸２２；８４４％，含１８种氨基酸成分。含可溶性糖１０．８６％，其糖分组成：蔗糖２．７３９％，葡萄糖０．９０９％，果糖０．６９８，及微量木糖与１种未鉴定糖。含纤维素２．２５％，含灰分５．３７％，含干物质９２．１０％。

By means of chemical analysis and gas chromatography and liquid chromatography amino acid analyzer, the chemical constituents of seeds of Dipteronia sinensis Olive. native to China have been studied, the following results showed that oil content of seeds is 29. 14%, its physical and chemical constent such as refractiveindes (20℃) is 1.4732, sapnifieation value is 178. 70, acid value is 6.90. The oil is composed of oil acid (36.7%), linoleic acid (24.2%),erucic acid (17.8%), arachidic oil acid (7.2%), linolenicacid (2.8%), palmific acid (6.7%), arachidic acid (3.0%), stearic acid (1. 5%) and a few palmitoleic, 16-C-2-alkem, beneic acid. The protein content is 29. 16%, it is composed of hydrolytic amino acid (22.84%), free amino acid (0.425%) and 18 kinds of amino acids are involued. The content of suggar have been identified with fructose (0.698%), glucose (0.91%), saccharose (2.74%) starch (8.55%) and cellulose (2.25%). Theash and dry substance content are 5. 37% and 92.10%.
