In vitro antimycotic activity of chemical constituents from Dipterocarpus verrucosus, Dipterocarpus cornutus and Diptericarpus crinitus against opportunistic filamentour fungi
This paper will discuss, in vitro investigation of chemical constituents extracted from the stem bark of Dipterocarpus verrucosus, Dipterocarpus crinitus and Dipterocarpus cornutus against opportunistic filamentous fungi. In this research, 17 compounds comprised of twelve oligostilbenoids, (-)--vin...

This paper will discuss, in vitro investigation of chemical constituents extracted from the stem bark of Dipterocarpus verrucosus, Dipterocarpus crinitus and Dipterocarpus cornutus against opportunistic filamentous fungi.
