Effects of different conditions of lotus rhizome states,inhibitor and temperature on lotus rhizome's B. D. and P. P. O. activity were investigated. Results show that B. D. of lotus rhizome was the lowest under the conditions of low temperature,lotus rhizome with ends cut,0.25% (w/v) ascorbic acid or 0.05% (w/v) sodium sulfite mixed with 0.2% (w/v) citric acid. The P. P. O. activity was weakened with the storage time.
