生物碱有很多类型,多数生物碱是含有氮原子的杂环化合物,少量生物碱对人和动物的神经系统有刺激作用,剂量较大时能使人难受或中毒。近10年发现生物碱达700种。国外研究证明,含有生物碱的植物有276种,属于39个科,共分离出495种生物碱。马铃薯中也含有生物碱。它们的分子中有一个糖苷配基,也叫葡糖生物碱,通常叫茄碱。马铃薯的野生种和栽培种中共发现20多种生物碱。马铃薯植株内葡糖生物碱的含量不同。芽和花含量最多,块茎内最少。在不同的生育期也不一样。马铃薯的幼嫩器官含量最多,随着植株的生长,葡糖生物碱大大减少
There are many types of alkaloids, most of the alkaloids are heterocyclic compounds containing nitrogen atoms, a small amount of alkaloids on human and animal nervous system stimulating effect, larger doses can make people uncomfortable or poisoned. Nearly 10 years found that up to 700 kinds of alkaloids. Foreign studies have shown that alkaloids containing 276 kinds of plants, belonging to 39 families, altogether 495 kinds of alkaloids isolated. Potatoes also contain alkaloids. In their molecule there is an aglycon, also known as a glucoalkylamine, usually called solanine. More than 20 alkaloids were found in wild and cultivated potato. The content of glucose alkaloids in potato plants is different. The highest content of buds and flowers, tubers within the least. In different stages of growth is not the same. Potatoes are the most abundant organs, with the growth of plants, glucose alkaloids greatly reduced
