Abstract:
OBJECTIVETo establish a method used for optimization of harvesting time and determine the best time for harvesting Rumex gmelini.
METHODAn HPLC method was applied to determinate the contents of seven active constituents(resveratrol, polydatin, chrysophanol 1-glucoside, nepodin, emodin, chrysophanol and physcion)of R. gmelini at different development stage. The result was analyzed by principal component analysis.
RESULTThe accumulation of active constituents showed a regular pattern.
CONCLUSIONThe best harvesting time of R. gmelini is early July.
