Chemical Constituents of Water Extract from Camptosorus sibiricus
is a kind of herbal medicine and famous folk medicine. However
the bioactivities or pharmacological effects of the
C
.
sibiricus
remain to be unclear. Therefore
it is necessary to make a systematic study on chemical constituents from
C
.
sibiricus
so as to further study its potential medicinal value
and provide certain chemical basis and foundation for the comprehensive development and the search for pharmacological activity.
Method:
2
Various column chromatographic technologies
(silica gel
Sephadex LH-20 and ODS column chromatography) as well as HPLC were adopted to separate chemical constituents of
C
.
sibiricus
extract. The structure of the purified compounds was elucidated by nuclear magnetic resonance (NMR) and high-resolution electrospray ionization-mass spectrometry (HR-ESI-MS).
Result:
2
Totally 10 compounds have been isolated from water extract of
C
