In the present study, the Lycium chinensis Miller was harvested at intervals of one month in order to distinguish outstanding species and to determine optimal harvest time. From these harvests, extracts were prepared from ethanol. The total usable sugar, betaine, and phenolic acid contents as well as electron-donating ability and SOD-liked activity of the extracts were then measured. While sugar content of the Lycium chinensis Miller showed no significant difference among the various species examined, usable sugar content of the crop harvested in November was higher than that of the crop harvested in August.
