前言麦角是妇产科的重要药物,国内每年用量很大,多由外国进口,每年资金外溢很多,所以在国内调查有效的野生麦角资源以代外货,是一件极有意义的工作。此外,麦角在农业上也是著名的黑麦病害,虽然影响黑麦的产量不大,但食用这种含有麦角菌核的面粉,含量如超过0.1%时,即能引起麦角中毒症。野生麦角也寄生在各种禾本科的牧草上,家畜吃了以后,也会产生麦角中毒症。所以麦角不但有医疗上的价值,而且与农业,畜牧业也有莫大的关系。过去对于国内麦角调查作得很少, Foreword Ergochelum is an important medicine for obstetrics and gynecology. Domestically, it is used in large quantities, mostly imported by foreign countries, and there are many funds spilling out every year. Therefore, investigating effective wild ergot resources on behalf of foreign materials in China is a very meaningful task. In addition, ergot is also a well-known rye disease in agriculture. Although it does not affect the yield of rye, consumption of this flour containing ergot nucleus can cause ergotism if it exceeds 0.1%. Wild ergots also parasitize grasses of various gramineae. After the animals eat them, they also develop ergotism. Therefore, ergot is not only of medical value, but also has a great relationship with agriculture and animal husbandry. In the past, little research was conducted on domestic ergots.
