Taking 20 Schisandra varieties as test materials,the effect of different varieties,different picking days,different management levels,different ages and different rough working methods on the lignans content were studied.The results showed that the lowest content of schizandrol was 3.566 g/kg,and the highest was 9.203 g/kg in 20 germplasms,indicating that the content of active ingredients were obviously different among germplasms；the lignan content of the same species(strain)from high level management was higher than that from low level one；after harvest,the Schisandra could be dried at the temperature of 40~50℃ for 65~72 hours,whereas it would taken 20~25 days under the conditions of sun drying or dried naturally.There was no significant effect on active ingredient content using above processing methods,but it would be decreased with temperature increased higher than 55℃.
