RESUMO
OBJECTIVE: Setting a valuable method of Pinellia ternate to provide references for germplasm evaluation of medicinal plant. METHOD: Nine germplasms were collected from seven primary cultivated or wild areas and were planted in field using randomined complete experimental design. Several important value were selected to give a general evaluation with marking. RESULT: In all collected materials, according to integrated mark, the first two exellent germplasm is Anyue 93.1, Yixian 87.5, which showed better characters. CONCLUSION: In the light of standard that whose mark exceeds 80 can be used as good germplasm, Anyue and Yixian materials are recommended.

OBJECTIVE: To determine the alkaloids content of Pinellia ternate in different growing time for finding out the best harvest time. METHODS: The alkaloid was extracted by chloroform from Pinellia ternate and tested at 417 nm with the spectroscopy by acid dye. The result was analyzed in One-Way ANOVA. RESULTS: The calibration curve of alkaloid was linear( r = 0.9989). The recovery rate was perfect (100.1%). The alkaloids content in different growing time had very significant difference ( F = 12.789, P < 0.01). CONCLUSION: This method is simple and quick. The alkaloids content in whole seedling stage is higher than that in other growing stages, while the mean total alkaloids output per plant is the highest in intensive seedling-downfallen stage which is considered as the best harvest time.
