Objective: The inter-simple sequence repeat(ISSR) reaction system of Polygalae Radix was optimized and a pair of polymerase chain reaction(PCR) primers was designed to rapidly predict the contents of sibiricose A5 and sibiricose A6 in Polygalae Radix. Method: The contents of sibiricose A5 and sibiricose A6 were determined by UPLC
and the ISSR reaction system of Polygalae Radix was optimized by single factor tests.The specific DNA fragments related to sibiricose A5 and sibiricose A6 were screened by ISSR
and a pair of specific PCR primers was designed for the fragments. Result: The contents of sibiricose A5 and sibiricose A6 were significantly different in 7 batches of Polygalae Radix
and the variation range of these two substances was 0.895 4-3.227 6
0.644 2-2.057 8 mg·g-1
respectively.After cloning and sequencing of 890-8 related to the contents of sibiricose A5 and sibiricose A6
a pair of specific primers (YZ-SA) was designed for rapidly predicting the contents of sibiricose A5 and sibiricose A6 in Polygalae Radix. Conclusion: The ISSR-PCR system established for Polygalae Radix shows the characters of clear marker site
reliable abundant polymorphisms and other characteristics.The specific PCR primers can be used to rapidly predict the contents of sibiricose A5 and sibiricose A6 in Polygalae Radix.
