摘 要 ：中国沙棘是分布在黄土高原地区的一个沙棘亚种。新鲜果实平均含水率为73.6%,含维生素C 738.2mg/100g(变化范围为378—1319mg/100g),胡萝卜素4.6—13.5mg/100g,有机酸3.32—5.30%,(其中苹果酸占67—71%),可溶性糖5.2—12.7%(其中葡萄糖占49.6%,果糖48.2%)。种子占果实重的5.8—7.9%。果肉含油2.05%,种子含油8.36%。影响果实化学成分变化的主要因素是生长环境,尤其是光照条件,以及果实的颜色类型。果肉油含胡萝卜素为54.0—102.6mg/100g,维生素E 40.1—61.8mg/100g,饱和脂肪酸32.8%,非饱和脂肪酸66.8%。种子油含胡萝卜素为27.8mg/100g,维生素E65.7—104.0mg/100g,饱和脂肪酸11.0%,非饱和脂肪酸88.9%。中国沙棘油中含有大量胡萝卜素和维生素E等天然药物成分是极为可贵的。

Abstract:Chinese Seabuckthorn (Hippophae rhamnoides subsp. sinensis) mainly distributes in the Loess plateau region of China. The result given by analysing the Chinese Seabuekthorn fruits demonstrates: fresh fruit contains 73.6% water, 738.2mg/100g Vitamin C(variation range: 378.0—1319.6mg/100g), 4.6—13.5mg/100g carotene, 3.23—5.30% organic acid, 5.2—12.7% soluble sugar; Malic acid is 67—71% by organic acid, glucose is 49.6% by soluble sugar and fruetose is 48.2% Seed is 5.8—7.9% by fruit weight. Fruit pulp contains 2.05% oil and seed contains 8.36% oil. The main factor influencing the change of chemical components is growing habitat, especially the light conditions, and the types of fruit colour.Oil of fruit pulp contains 54.0—102.6mg/100g carotene, 40.1—61.8mg/100g Vitamin E, 32.8% saturated fatty acid and 66.8% unsaturated fatty acid Oil of seed contains 27.8mg/100g carotene, 65.7—104.0mg/100g Vitamin E, 11.0% saturated fatty acid and 88.9% unsaturated fatty acid. There is a great capacity of Vitamin E and carotene in the oil of Chinese Seabuekthorn fruits, which is very precious.
