红松籽油有效成分功能评价(英文)

Functional evaluation for effective compositions in seed oil of Korean pine

红松是分布于中国东北的珍贵树种,其种籽油中含有丰富的生物活性物质,对人体的生理活动具有重要的调节功能。为评价红松籽油的功效,本文就红松籽油对大鼠血脂的影响及其抗衰老功能进行了研究,对不同组的大鼠喂添加了不同含量的种籽油的饲料。将60只大鼠随机地分成五组(每组雌雄各半)。实验过程中,用松籽油处理的三个组的大鼠分别喂食含2.0g/(kgd-1),4.0g/(kgd-1)和8.0g/(kgd-1)剂量松籽油的饲料。用试剂盒法对超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH-PX)以及抗氧化(AOC)等指标进行了测定。经研究发现松籽油可以降低血清甘油三酯含量,提高血清SOD和GSH-PX的活力。其中喂食4.0g/(kgd-1)剂量红松籽油的一组,其各项测定指标均达到显著水平;喂食8.0g/(kgd-1)剂量红松籽油的一组达到了极显著水平。结果表明,红松籽油具有调节血脂和抗衰老作用。图2表3参9。

The effect of seed oil of Korean pine (Pinus koraiensis) on the rats' blood-fat and its anti-ageing function was stud-ied for appraising the efficacy of the seed oil of Korean pine. Sixty experimental rats were randomly divided into 5 groups (half males and half females in each group) as normal control group, high fat diet control group, and three groups (Group 1 Group 2, Group 3) that were fed with feedstuff with the contents of the seed oil of 2.0g/(kg d-1), 4.0g/(kg d-1) and 8.0g/(kg d-1), respec-tively. The indexes such as superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and anti-oxidation capacity (AOC) were measured by Reagent Kit method. It was found that the seed oil of the Korean pine could reduce the content of triglyc-eride and improve SOD as well as GSH-PX activity in serum. These indexes of the rats in Group 2 fed with Korean pine seed oil of 4.0 g/(kg d-1) reached the significant level and those of rats in Group 3 fed with the seed oil of 8.0 g/(kg d-1) reached the extremely significant level. The results indicated the seed oil of Korean pine had function of regulating the level of blood-fat and anti-ageing.
