摘要: 对南方红豆杉种子的营养成分及假种皮的急性毒性进行分析。结果表明:南方红豆杉假种皮中的可溶性固形物8.3%、可溶性糖10.28%、粗蛋白1.39%、粗纤维2.17%、粗脂肪2.76%、VC 16.31mg/100g。种仁含油率28.55%,种仁中共检出6种脂肪酸,其中不饱和脂肪酸(油酸、亚油酸、二十烯酸)占总脂肪酸的94.59%。假种皮含15种氨基酸,其中8种必需氨基酸占总氨基酸的43.71%。在常量和微量元素中,分别以Ca和Fe的含量较高。以剂量16.5g/kg的假种皮灌胃小鼠急性毒性实验发现,小鼠连续14d没有出现明显的中毒症状和死亡现象,初步表明南方红豆杉假种皮没有急性毒性。

Abstract: This study was designed to analyze the nutritional composition of Taxus chinensis var. mairei seeds and the acute toxicity of its aril. The seed aril of Taxus chinensis var. mairei was found to contain 8.3% soluble solid, 10.28% soluble sugar, 1.39% crude protein, 2.17% crude fiber, 2.76% crude fat and 16.31 mg of vitamin C per100 g of sample. The oil content of its seed kernel was 28.55% and 6 fatty acids were identified from the seed oil of Taxus chinensis var. mairei, including 4 unsaturated fatty acids (oleic acid, two linoleic acid isomers and 11-eicosenoic acid) with a relative content 94.59%. The seed aril of Taxus chinensis var. mairei contained 15 amino acids and 8 essential amino acids accounted for 43.71% of total amino acids. Ca as a relatively abundant major element and Fe as a relatively abundant trace element were detected. No obvious poisoning symptoms and no deaths were observed in mice during 14 days after oral administration of the seed aril of Taxus chinensis var. mairei., suggesting that this material had no acute toxicity.

Key words: Taxus chinensis var. mairei, aril, nutritional components, acute toxicity test
