[Study on activity of inner inhibitory substances of Acanthopanax senticosus (Rupr. et Maxim) harms fruits and seeds].

OBJECTIVE

By studying on the inner inhibitory substances of Acanthopanax senticosus fruits and seeds, the reason for dormancy of the Seeds was investigated.

METHOD

First, the raw extracts of Acanthopanax senticosus fruits and seeds were prepared and determined by biological methods. Then, the ether extract of Acanthopanax senticosus fruits was prepared and the components were separated by paper chromatography and each section with different Rf value was determined, respectively.

RESULT AND CONCLUSION

Inner inhibitory substances with high activity exists in Acanthopanax senticosus fruits and their outer coats, middle coats and the seeds. The inner inhibitory substances showed stronger inhibitory effect on the germination of Brassica chinensis seeds than the growth of its younger roots. The Rf 0.1 section of the ether extract of Acanthopanax senticosus fruit coats showed the strongest inhibitory activity on the germination of Brassica chinensis seeds and the growth of its young roots. The rough extracts of Acanthopanax senticosus fruits could inhibit the activity of the (alpha-amylase in the process of wheat seeds germination. The dormanvy of Acanthopanax senticosus seeds is related to the inhibitory substances with high activity in Acanthopanax senticosus fruits and seeds.
