High levels of gene diversity were revealed in these two medicinal species, the majority of genetic diversity was harbored within populations, and population structure was might due to restricted gene flow among populations. Isolation by distance was close to significance in S. chinensis but not in S. sphenanthera. In S. chinensis, null alleles were identified as a cause for excess of homozygotes at loci G24 and WGA60, but inbreeding might also be partly responsible for the positive F IS values in this species. In contrast, null allele frequencies were high at all the seven loci in S. sphenanthera and resulted in overestimation of fixation index. The strategy for ex situ conservation of these two medicinal species is discussed based on the genetic results.
