Fatty Acids from Ranunculus ternatus

Abstract:

The aim is to investigate the chemical constituents of Ranunculus ternatus Thunb. Five fatty acids are isolated from tubers of R. ternatus. On the basis of spectral data, they are identified as (R)-3-hydroxy- 11-methoxy-11-oxoundecanoic acid (1), palmitic acid (2), ethyl palmitate (3), adipic acid (4) and stearic acid (5). Compound 1 is a new compound. All compounds have a certain inhibitory activities in vitro against multidrug- resistant strain.
