GC-MS Profile of Diodella sarmentosa (SW) Bacigalupo El Cabral ex Borhidi Ethanol Leaf Extract and its Total Dehydrogenase Inhibitory Potential [PDF]

open access: yesarXiv, 2021
Phytochemical composition of ethanol leaf extract of Diodella sarmentosa was profiled with GC-MS and the inhibitory property of the extract against total microbial dehydrogenases were assessed. The major constituents of the extract were squalene (29.50%), Phytol (24.68%), phenol, 3-pentadecyl- (18.58%), 1-Butanol, 3-methyl- (9.09%) and n-Hexadecanoic ...
