5个杂交沙棘品种果实营养成分比较分析

为综合开发沙棘生物资源，以杂雌优1号、杂雌优2号、杂雌优10号、杂雌优12号、杂雌优54号等5个杂交沙棘果实为试材，比较分析果实中维生素C、维生素E、总黄酮、花青素、可滴定酸、β-胡萝卜素、可溶性糖、葡萄糖、果糖、蔗糖等营养成分含量、超氧化物歧化酶（SOD）活性及其相关性。结果表明，各营养成分含量与沙棘品种及成熟度有关。参试5种杂交沙棘品种完全成熟时，维生素C和维生素E含量分别可达318.28～531.78 和7.60～13.14 mg/100 g，可溶性糖和可滴定酸含量分别为32.61~84.36 mg/g、0.97%~1.95%，β-胡萝卜素和总黄酮含量分别为22.31~47.82 μg/g、1.41~3.53 mg/g。参试5种杂交沙棘品种中，杂雌优10号沙棘果实营养成分含量较高。相关性分析显示，5个杂交沙棘果实的V_E、β-胡萝卜素、花青素、葡萄糖、总黄酮含量互为极显著正相关（P<0.01）。研究结果为杂交沙棘在食品、保健品等方面的加工利用提供理论依据。

Analysis of Nutrient Compositions in Five Hybrid Sea Buckthorn Varieties Berries

In order to comprehensively develop the biological resources of sea buckthorn, five hybrid sea buckthorn berries including Zaciyou 1, Zaciyou 2, Zaciyou 10, Zaciyou 12, and Zaciyou 54 were used as test materials to compare and analyze. The vitamin C, vitamin E, total flavonoids, anthocyanins, titratable acids, β-carotene, soluble sugar, glucose, fructose, sucrose content and superoxide dismutase (SOD) enzyme activity were determined and their correlations were analyzed. The results showed that the content of each nutrient component was related to the variety and maturity of sea buckthorn. When the five hybrid sea buckthorn varieties participated in the test were fully mature, the content of vitamin C and vitamin E could reach 318.28~531.78 and 7.60~13.14 mg/100 g, respectively, and the content of soluble sugar and titratable acid could reach 32.61~84.36 mg/g, 0.97%~1.95%, the contents of β-carotene and total flavonoids could reach 22.31~47.82 μg/g and 1.41~3.53 mg/g, respectively. Among the five hybrid sea buckthorn varieties tested, Zaciyou 10 sea buckthorn had higher nutritional content. Correlation analysis showed that the contents of V_E, β-carotene, anthocyanin, glucose and total flavonoids in the five hybrid sea buckthorn berries were very significant correlation with each other (P<0.01). The research results would provide a theoretical basis for the processing and utilization of hybrid sea buckthorn in food and health care products.
