毒理性
鉴定和使用:(+)-氧化白芷素是白芷(Peucedanum ostruthium (L) Koch)的一个组成部分,白芷在奥地利的高山地区传统上被用作利口酒和苦味酒的成分,也作为草药药物。它已经被测试为实验性治疗。人体研究:在体外测试时,它显示出适度的保肝活性。动物研究:在大鼠中测试时并未显示出肝毒性。口服氧化白芷素后,在2周大的小鸡中产生了光敏性。2周大的小鸡和2周大的火鸡雏鸡分别被喂食0.4%、0.8%和1.6%体重的大花金挖耳(C. watsonii)种子或全株,或者是长脚金挖耳(C. longipes)的种子,然后每天在阳光下放置5小时,持续7天。所有植物材料都在小鸡中产生了中到重度光敏性。毒性症状包括畏光;喙、鸡冠和脚的红色变色;眼周区域的羽毛脱落;鸡冠和喙边缘的干性浆液性分泌物;角膜结膜炎;以及脚和腿上的多个病变。火鸡雏鸡表现出与小鸡相似的症状。喂食长脚金挖耳种子的火鸡的死亡率特别高。治疗6周后火鸡的毒性症状包括腿部的震颤;上喙的上翻和缩短;以及脚趾的缩短、变形和坏疽。
IDENTIFICATION AND USE: (+)-Oxypeucedanin is a component of Peucedanum ostruthium (L) Koch (masterwort), traditionally used in the alpine region of Austria as an ingredient of liqueurs and bitters and as a herbal drug. It has been tested as experimental therapy. HUMAN STUDIES: It demonstrated moderate hepatoprotective activity when tested in vitro. ANIMAL STUDIES: It was not hepatotoxic when tested in rats. Oxypeucedanin administered orally, produced photosensitivity in 2 wk old chicks. Two week old chicks and 2 wk old turkey poults were fed seed or whole plants of C. watsonii or seed of C. longipes at 0.4, 0.8 and 1.6% of body wt, and then placed in sunlight for 5 hr each day for 7 days. All plant material produced moderate to severe photosensitivity in chicks. Toxic signs included photophobia; red discoloration of beak, comb and feet; loss of feathers in the periorbital area; dried serous fluid on the comb and edge of the beak; keratoconjunctivitis; and multiple lesions on feet and legs. Turkey poults showed a syndrome similar to that of chicks. Mortality was particularly high in turkeys fed C. longipes seed. Toxic signs in turkeys 6 wk after treatment included tremors in the legs; upturning and shortening of the upper beak; and shortening, disfigurement and gangrene of the toes.
