An antifungal naphthoquinone, xanthones and secoiridoids from Swertia calycina
|Published in||Planta Medica. 1995, vol. 61, no. 4, p. 362-364|
|Abstract||A chemical and biological screening of 25 species of the Gentianaceae family has been undertaken. Both methanolic and dichloromethane extracts of Swertia calycina exhibited a strong antifungal activity against Cladosporium cucumerinum and Candida albicans. The compound responsible for this activity has been isolated and identified as 2-methoxy-1,4-naphthoquinone. It is the first naphthoquinone to be described in Gentianaceae species. LC-UV and LC-TSP-MS analysis of the crude extracts of Swertia calycina also allowed on-line identification of six known xanthones and secoiridoids.|
