Abstract

Salvia miltiorrhiza Bge. f. alba is a traditional Chinese herbal drug with special pharmacological effect on thromboangiitis obliterans. However, the nature source of S.miltiorrhiza Bge.f.alba is now in short supply because of the over-collection of the wild plant. To better utilize this resource, the diversity and antioxidant activity of endophytic fungi isolated from S. miltiorrhiza Bge. f. alba were investigated. A total of 14 endophytic fungi were isolated from different parts of S. miltiorrhiza Bge.f.alba. Based on morphological and molecular identification, the endophytic fungi isolated were classified into four genera (Alternaria sp., Fusarium sp., Schizophyllum sp. and Trametes sp.). These fungal extracts were prepared using ethanol and evaluated for their phytochemical compounds and antioxidant activity. Alternaria alternata SaF-2 and Fusarium proliferatum SaR-2 are of particular interest because they yielded all of nine phytochemicals including saponins, phenol, flavonoids, cardiac glycosides, steroids, tannins, alkaloids, anthroquinone and terpenoids. F. proliferatum SaR-2 and A. alternata SaF-2 also exhibited stronger antioxidant activities by FRAP and DPPH method, having the higher levels of phenol and flavonoid th...Continue Reading
