Two new gibberellins, gibberellins Ae6 and Ae~ (GA2~ and GA2:), and their glucosides have been isolated from immature seeds of Japanese morning-glory (Pharbiti8 nil), together with GA s and its glucoside. GA~6, GA2~ and their glucosides showed only slight growth-promoting activities on seedlings of
## Abstract 2β__O__βGA~29~Ξ²βDβglucopyranoside (1e) and 13β__O__βGA~29~, Ξ²βDβglucopyrβanoside (1h) were synthesized from GA~29~ methyl ester (1b). Their structures were confirmed by ^1^H NMR and GCβMS. Likewise, [17β^13^C,T~2~]βlabelled 1e and 1h could be obtained. From [17β^13^C,T~2~]GA~20~ (2a) an
