三烯生育酚 γ-Tocotrienol
维生素E(Vitamin E)是一种脂溶性维生素,其水解产物为生育酚,是最主要的抗氧化剂之一。[1] 溶于脂肪和乙醇等有机溶剂中,不溶于水,对热、酸稳定,对碱不稳定,对氧敏感,对热不敏感,但油炸时维生素E活性明显降低。生育酚能促进性激素分泌,使男子精子活力和数量增加;使女子雌性激素浓度增高,提高生育能力,预防流产,还可用于防治男性不育症、烧伤、冻伤、毛细血管出血、更年期综合症、美容等方面。近来还发现维生素E可抑制眼睛晶状体内的过氧化脂反应,使末梢血管扩张,改善血液循环,预防近视眼发生和发展。维生素E苯环上的酚羟基被乙酰化, 酯水解为酚羟基后为生育酚。人们常误认为维生素E就是生育酚。

Description The four tocopherols (α, β, δ, and γ) and four tocotrienols (α, β, δ, and γ) are forms of vitamin E, which is known for its antioxidant activity.1 Tocotrienols are found in high concentrations in palm oil and rice bran. Recent studies observe that tocotrienols may be more effective antioxidants than α-tocopherol, the most abundant form of vitamin E.2 Spontaneously hypertensive rats fed a diet which includes γ-tocotrienol show significant reduction of systolic blood pressure and an increase of nitric oxide synthase activity in blood vessels.3 γ-Tocotrienol at 20 µM induces apoptosis of malignant sympathoadrenal (+SA) murine mammary epithelial cells.4
