(Myrrhinaceae) have different bioactivities. There are intensive studies for chemical constituents of its leaves and fruits at present. However
there are a few studies for the roots. Therefore
we systematically investigated the chemical constituents of phenolic acids in roots of
P
.
guajava
.
Method:
2
The chemical constituents were isolated and purified by various column chromatography methods and semi-preparative HPLC. The isolated compounds were identified by physicochemical properties and spectral analysis.
Result:
