冬虫夏草:从雪域秘境到科学前沿的解码之旅OA

Ophiocordyceps sinensis(Berk)Sacc.(O.sinensis;Family:Clavicipitaceae;synonym:Cordyceps sinensis)is a fungus that is revered in ancient Tibetan folklore as a"miraculous species that becomes a worm in winter and a grass in summer"and renowned as the"elixir of life gifted"by the snow-capped region.Its evolutional awareness and utilization span both traditional Chinese medicine practices and modern biomedical research,rendering it a quintessential example of symbiotic entomo-fungal biological resource development.Extensive research on the biological characteristics,active constituents,pharmacological effects,and underlying mechanisms of O.sinensis has generated significant breakthroughs in recent years.From"heavenly elixir"to a vital tonic in imperial cuisine,and from its symbiotic life cycle to its current prominence in modern pharmacological research and clinical applications,this fungus has nurtured both the cultural legends and survival wisdom of the Plateau ancestors and reflected the long journey of contemporary scientific exploration and industrialization.This review traces the journey of O.sinensis from traditional empirical applications to scientific validation,focusing on its biological characteristics,extraction and separation techniques for key bioactive constituents,and its pharmacological effects and molecular mechanisms in antitumor activity,immunomodulation,renoprotection,antioxidant properties,and anti-aging effects,and summarizes the current status of its clinical applications.Furthermore,this review examines the challenges confronting current research on O.sinensis,including resource conservation and sustainable utilization,quality control and standardization,differences between artificially cultivated and wild-harvested specimens,further elucidating its mechanisms of action and outlining prospects for future research directions.
