生物碱类化学成分结构复杂、种类繁多，广泛存在于兰科各属植物中，且大多具有抗炎、抗肿瘤、降血糖、细胞毒性等生物活性。系统综述了兰科生物碱类化学成分的植物分布、种类结构及药理作用，为兰科植物中生物碱类成分的结构类型、结构解析及生物活性的深入研究提供理论参考。

Due to the complex chemical compositions and various types, alkaloids are widely existed in various genera of Orchidaceae plants. Most of the alkaloids have anti-inflammatory, antitumor, hyperglycemic, cytotoxic and other biological activities. In this paper, the distribution, types, structures, and pharmacological action of alkaloids in Orchidaceae plants were reviewed, which provides a theoretical reference for the structure type, structure analysis, and biological activity of alkaloids in Orchidaceae plants.
