Abstract

Batatasin I was isolated from non–dormant bulbils of Dioscorea opposita Thunb. (= D. batatas Decne.). Such non–dormant bulbils were devoid of the bibenzyl derivatives batatasins III, IV and V. It is therefore suggested that the dormancy of the yam bulbils is determined primarily by the bibenzyl batatasins.
