据山东、浙江等地报道,豆科植物“农吉利”对鳞状上皮癌有一定的疗效。中国科学院武汉植物园的同志发现我省有农吉利的同科植物大叶猪屎青(Crotalaria assamica Benth)的生长,并从其种子中提取出有效成分的结晶(含量为3％),定名为“大叶猪屎青碱”。经化学分析它可能与农吉利碱Ⅰ、农吉利甲素及野百合碱为同一物质。我们对大叶猪屎青碱的抗肿瘤作用及其毒性进行了初步的实验研究,现将其结果摘要如下。 According to reports from Shandong, Zhejiang and other places, “Legongli”, a leguminous plant, has a certain effect on squamous cell carcinoma. Comrades from the Wuhan Botanical Garden of the Chinese Academy of Sciences found that the province has the growth of Crotalaria assamica Benth, the same plant with the same family, and extracted the active ingredient (3%) from its seeds and named it “ Big leaf swine catalase ”. It may be the chemical analysis of Nongji Li base Ⅰ, Nong Keyline A and monocrotaline for the same substance. We conducted a preliminary experimental study of the antitumor effect of Cyperus rotundus and its toxicity, the results of which are summarized as follows.
