The seasonal changes of oxindole alkaloid content in stem segments of Uncaria rhynchophylla were investigated between July 1986 and June 1987. The highest oxindole alkaloid content in the dried stem segments was observed in July 1986,and the content decreased until the next spring, when it started to increase again. In contrast, high biomass production was obtained in winter (November and December). The optimum season to prepare the crude drug from U. rhynchophylla is discussed in relation to oxindole alkaloid content and biomass yield
