两种形态蛹虫草菌株子实体及有效成分比较

在蛹虫草资源调查中，发现两种子实体形态迥异的蛹虫草菌株T和G。栽培试验表明，T菌株子实体矮化膨大，G菌株子实体为棒状．两者子实体长度、直径和产量差异显著。有效成分测定结果表明，菌株T和G子实体中粗多糖的含量分别为1．75％，1．77％，虫草酸为2．81％，2．57％，超氧化物歧化酶（SOD）酶活分别为30．43U／mgprotein、53．49U／mgprotein，过氧化物酶（POD）分别为31．26U／mgprotein，33．49U／mgprotein，过氧化氢酶（CAT）分别为126．35U／mgprotein、137．46U／mgprotein。其中，虫草酸含量、SOD酶活两者差异均显著。

Comparison of Fruiting Bodies and Effective Components of Two Forms of Cordyceps Militaris Strains

In resource survey of eordyceps militaris, we found 2 C.militaris strains T and G of different form. Cultivation experiment showed that fruiting body strain T was dwarf and big, while the fruiting body of strain G was elavate. The length, diameter and yield of fruiting body were significantly different. The determination results of the effective components showed that crude polysaeeharide content of strain T and strain G was respectively 1.75% and 1.77%, eordyeeps acid was respectively 2.81% and 2.57%, superoxide dismutase （SOD）enzyme activity was respectively 30.43 U/mg protein and 53.49 U/mg protein, peroxidase （POD） enzyme activity was respectively 31.26 U/mg protein and 33.49 U/rag protein, eatalase （CAT） enzyme activity was respectively 126.35 U/rag protein and 137.46 U/rag protein. Cordyeeps acid content and SOD enzyme activity were both not significantly different.
