| total phenolic content and antioxidant activity of mycelial extracts from the medicinal fungus paecilomyces hepiali (ascomycetes). | paecilomyces hepialid, a fungus originating in the tibetan plateau, has been used as a substitute for ophiocordyceps sinensis because the primary chemical compounds and pharmacological effects of p. hepialid are similar to those of o. sinensis. p. hepialid has been developed into a dietary supplement and pharmaceutical products. the antioxidant activity of extracts using 2 solvents (water and ethanol) from mycelia obtained from 2 cultivation modes (solid-state and submerged cultivation) were eva ... | 2017 | 28322145 |
| laboratory rearing of thitarodes armoricanus and thitarodes jianchuanensis (lepidoptera: hepialidae), hosts of the chinese medicinal fungus ophiocordyceps sinensis (hypocreales: ophiocordycipitaceae). | ophiocordyceps sinensis (ophiocordycipitaceae) is an entomopathogenic fungus endemic to the tibetan plateau, at elevations ranging between 3,000 and 5,000 m. the fungus-insect complex is useful in healthcare but limited in the field, so there is an urgent need to develop an artificial rearing system of both the fungus and its insect hosts. large-scale artificial rearing of the thitarodes insect hosts is crucial. this paper reports results of the artificial cultivation and complete life tables of ... | 2016 | 26567334 |
| phylogeography and evolution of a fungal-insect association on the tibetan plateau. | parasitoidism refers to a major form of interspecies interactions where parasitoids sterilize and/or kill their hosts typically before hosts reach reproductive age. however, relatively little is known about the evolutionary dynamics of parasitoidism. here, we investigate the spatial patterns of genetic variation of chinese cordyceps, including both the parasitoidal fungus ophiocordyceps sinensis and its host insects. we sampled broadly from alpine regions on the tibetan plateau and obtained sequ ... | 2014 | 25263531 |
| a survey of the geographic distribution of ophiocordyceps sinensis. | ophiocordyceps sinensis is one of the best known fungi in traditional chinese medicine. many efforts have been devoted to locating the production areas of this species resulting in various reports; however, its geographic distribution remains incompletely understood. distribution of o. sinensis at the county level is clarified in this work based on both a literature search and fieldwork. more than 3600 publications related to o. sinensis were investigated, including scientific papers, books, and ... | 2011 | 22203553 |
