Study on the quality classification standard of Panax quinquefolium L. seeds.
[Object] To establish the quality classification standard of Panax quinquefolium L.seeds.[Method] 36 batches of Panax quinquefolium L.seeds from the main producing area of Jilin Province were selected as tested materials,the purity,1 000-grain weight,moisture content and viability of which were determined and analyzed through SPSS software,so as to establish the quality classification standard of Panax quinquefolium L.seeds.[Result] 1 000-grain weight and viability of the seeds were chosen as the main indexes for classification,other indexes could be references.The grade of Panax quinquefolium L.seeds was divided into 3 levels,i.e.the seeds with 99.05% viability and of 40.26 g in 1 000-grain weight were listed as the first grade;the seeds with the viability ranged from 96.96% to 99.05 and of the 1 000-grain weight ranged from 37.60 to 40.26 g were listed as the second grade;the seeds with the viability ranged from 95.47% to 96.96% and of the 1 000-grain weight ranged from 35.58 to 37.60 g were listed as the third grade.[Conclusion] The quality classification standard of Panax quinquefolium L.seeds has been initially established in this paper.
