白鲜的生物学与化学成分研究进展

中药白鲜皮为芸香科植物白鲜的干燥根皮，为中国重要的大宗药材之一，有着悠久的药用历史。近年来国内外对药用白鲜展开了多方面的深入研究。论述了白鲜原植物、地理分布、形态结构、种子特性以及组织培养等生物学特性以及化学成分挥发油、生物碱、柠檬苦素类、白鲜粗多糖等方面的研究现状。指出市场对白鲜皮需求量的增加、人工栽培鲜有开展及无序的滥采乱挖，导致白鲜野生资源日渐枯竭，并从增强认识与合理保护、综合开发利用、快速繁殖以及规范化栽培等方面作了总结，以期为白鲜植物资源的合理保护和可持续开发利用提供参考。

Advance on Biology and Chemical Constituents of Dictamnus dasycarpus

Dictamni Cortex is from the dry root cortex of Dictamnus dasycarpus in Rutaceae, which is an important traditional Chinese medicine and is used as an herb for a long time in Chinese history. Too much about Dictamnus dasycarpus has been studied. The biological characteristics on the origin, distribution, morphology and structure, seed germination, tissue culture, and the chemical constituents of essential oils, alkaloids, limonoids and coarse polysaccharide of Dictamnus dasycarpus are concluded. The current situation of Dictamnus dasycarpus suggests that over-need for Dictamni Cortex, disorderly collecting and seldom cultivating lead to resource exhausting seriously. In order to provide theoretical basis for further protection, development and utilization of Dictamnus dasycarpus, the suggestions about deeply understanding and reasonable protection, comprehensive development and utilization, rapid propagation and standardized cultivation are also provided.
