All of the seven species in Impatiens contain raphides.
结果表明,7种凤仙花属植物茎的解剖学结构非常近似,而茎中草酸钙结晶特征则差异显著,7种凤仙花属植物茎中均有草酸钙针晶,根据草酸钙结晶形态特征的不同,将针晶分为3种类型,即针晶束、针晶簇和散针晶。
Objective: Confirm the irritation of needle-like calcium oxalate crystals in raw Pinellia ternata.
目的:验证生半夏中草酸钙针晶的刺激性作用。
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.
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。
Results showed that the needle crystal of calcium oxalate hydrate(C2CaO4·H2O)was one of the major stimulating components of fresh taro leaf petioles,and its shape,and contents related to the stimulation of fresh taro leaf petioles.
结果显示：芋杆中含有的草酸钙针晶为芋杆的主要刺激性成分之一,其晶形、含量与芋杆的刺激性有关。
