流行病学及部分实验研究结果表明一些类胡萝卜素成分不经转化为维生素A就可发挥抑癌作用。本实验研究发现补充冬寒菜类胡萝卜素(42.27mg胡萝卜素/Kg饲料)能有效地抑制二乙基亚硝胺诱发大鼠肝细胞癌及肺转移癌的发生,并可有效地延长肿瘤的潜伏期及荷瘤动物的平均寿命。而补充丙酮-石油醚混合液提尽全部色素的冬寒菜提取后干粉无类似作用。
Epidemiology and some experimental studies show that some carotenoids can play a role in tumor suppression without being converted to vitamin A. The experimental study found that winter carotene carotene (42.27mg carotene / Kg feed) can effectively inhibit the diethylnitrosamine-induced hepatocellular carcinoma and lung metastases in rats, and can effectively extend the tumor Latency and average life expectancy of tumor-bearing animals. And add acetone - petroleum ether mixture to make all the color of winter cold extract of dried cabbage no similar effect.
