在探讨如何除去柑桔中苦味物质的过程中,美国科学家发现诺米林(一种三萜苦味素)有抗癌作用。实验证明,28％的实验鼠食入强效致癌物后,诺米林可抑制胃癌性肿瘤形成。另一种苦味化学物质柠檬甙也有抗癌效应,但效果差的多。研究人员还发现了诺米林和柠檬甙的衍生物。他们将进一步研究:衍生物是否同样具有原物质的抗癌 In discussing how to remove the bitter substances in citrus, American scientists found that numillin (a triterpene bitter) has anti-cancer effects. Experiments show that 28% of rats fed a potent carcinogen, nocturnal inhibition of gastric cancer formation. Another bitter chemical also has anti-cancer effects of lemon chemicals, but the effect is much worse. Researchers also found derivatives of nomelin and lemonosides. They will further study: whether the same derivatives of the original anti-cancer
