Abstract

Anticandidial activity of seven herbal extracts, Taraxacum Platycarpum, Houttuyniae Herba, Lonicerae Flos, Anemarrhena Rhizome, Forsythia Fruit, Paeoniae Ratix, and Coptidis Rhizoma, were determined against five different Candida sp. by agar diffusion assay. The concentration of total phenolic compounds of seven herbal extracts ranged from 0.6 to $2.5{mu}g/mg$. The total antioxidant activities showed that Taraxacum Platycarpum and Houttuyniae Herba were 60% in 80% ethanol extract and Lonicera Flower and Paeoniae Ratix were 70, 75%, respectively, in 100% ethanol extract. Coptidis Rhizoma extract showed antifungal activity against non-Candida albicans, C. tropicalis and C. glabrata. The MIC values of a compound separated in TLC from Coptidis Rhizoma extract were 24, and $48{mu}g/mL$ against C. tropicalis and C. glabrata. The above compound showed the same retention time with berberin in HPLC analysis.
