ABSTRACT
To obtain the difference of the fungal and bacterial community diversity between wild Cordyceps sinensis, artificial C. sinensis and their habitat soil, Illmina Hiseq high-throughput sequencing technology was applied. The results show that Proteobacteria was the dominant bacterial phylum in C. sinensis, Actinobacteria was the dominant bacterial phylum in soil microhabitat, Ophiocordyceps sinensis was the predominant dominant fungus of C. sinensis. The α diversity analysis showed that the fungal diversity of stroma was lower than other parts, and the fungal diversity of wild C. sinensis was lower than that of artificial C. sinensis. The β diversity analysis showed that the fungal and bacterial community diversity of soil microhabitat samples was significantly different from that of C. sinensis. The fungal community diversity was less different between wild and artificial C. sinensis, especially in sclerotia. LEfSe analysis showed a lot of species diversity between wild and artificial C. sinensis. Those different species between wild C. sinensis, artificial C. sinensis and their habitat soil provide ideas for further research on breed and components of C. sinensis.

OBJECTIVE: To observe the immune enhancement and anti-aging activities of cultivated and wild Cordyceps sinensis. METHODS: Mice were randomly divided into seven groups: high dose cultivated Cordyceps sinensis group, low dose cultivated Cordyceps sinensis group, high dose wild Cordyceps sinensis group, low dose wild Cordyceps sinensis group, control group, model group and positive drug group. Immunosuppression mouse model were induced by cyclophosphamide and the physical status, carbon clearance capacity, phagocytosis coefficient and lymphocyte transformation stimulation index, and ear swelling of mice were observed. The aging mice model was established by subcutaneously injecting D-galactose, and brain histology, antioxidant and anti-inflammatory capacity of mice were observed. RESULTS: Both cultivated and wild Cordyceps sinensis increased the body weight and immune organ index, and enhanced the immunity of the mice. Furthermore, both cultivated and wild Cordyceps sinensis ameliorated the pathological changes in brain histology, and enhanced the antioxidant and anti-inflammatory ability of the mice. There was no obvious difference in the immune enhancement and anti-aging activities between cultivated and wild Cordyceps sinensis. CONCLUSION: Both cultivated and wild Cordyceps sinensis can improve immunity and retard the aging process. Cultivated Cordyceps sinensis can be used as the alternative choice of wild Cordyceps sinensis in clinic.
ABSTRACT
OBJECTIVE To observe the renal protective effect of cultivated and wild Cordyceps sinensis on the the model mice of kidney-Yang deficiency, and to compare the differences of pharmacological effects between cultivated and wild Cordyceps sinensis. METHODS The model mice of kidney-Yang deficiency was induced by hydrocortisone in male mice which were randomly divided into seven groups: high dose group of cultivated Cordyceps sinensis, low dose of cultivated Cordyceps sinensis, high dose group of wild Cordyceps sinensis, low dose group of wild Cordyceps sinensis, control group, model group and positive drug group. The seven groups'index of physical status, swimming duration, gonad organ and immune organ, renal and testicular histology were observed. RESULTS Both cultivated and wild Cordyceps sinensis increased the body weight, prolonged the swimming time, improved sexual organ and immune organ index, ameliorated the pathological changes in renal and testicular histology, and enhanced the antioxidant ability of the model mice of kidney-Yang deficiency. There was no obvious difference in renal protective effect between cultivated and wild Cordyceps sinensis. CONCLUSION Both cultivated and wild Cordyceps sinensis can improve the kidney-Yang deficiency in male mice induced by hydrocortisone. Cultivated Cordyceps sinensis can be used as the alternative choice of wild Cordyceps sinensis in clinic.
