摘　　要：天南星科植物可被作为观赏性和药用植物,但大部分都有刺激性毒性。通过对国内外文献的查阅,发现大多数研究报告均将其刺激性成分认为是该科植物中所含有的特殊生物代谢产物草酸钙针晶,这与本课题组前期对半夏研究中得出的半夏中草酸钙针晶是其主要刺激性成分的结论一致。草酸钙针晶产生刺激性毒性的机制被认为与其特殊的针形晶型,针晶上所附的蛋白酶类物质及植物中黏液细胞相关。Plants in Acaceae family are often considered as ornamental and medicines. However many of them have irritation properties. As medicinal plants some of them are recorded in Chinese Pharmacopoeia and they are figured as poisonous. Through investigating the domestic and overseas studied paper, the needle-like calcium oxalate crystal exits in the plants of Acaceae family could be thought as irritation components of them . This conclusion is same with the studied conclusion of our study group in the medicines plant of Pinellia ternate belonging to the Acaceae family and our studies showed that the needle-like calcium oxalate crystal was the main irritation component of raw P. ternate. The irritated mechanism of raphides is relevant to its special shape, the protein enzyme adhering to it and idioblasts in plants.
