Gibberellin-like substances have been shown to occur in iss&ure seeds of Lupinus Zuteus (1-4) and an attempt was made to purify two active principles, which were tentatively named as Lupinus gibberellin I and II (5) . The former structure, whose provisional name was \*\* renamed as gibberellin Al8

Isolation and. biological activities of new gibberellins A26 and A27 in immature seeds of the Japanese morning-glory (Pharbitis nil) have been reported - (1). We wish to report here the elucidation of their structures. Gibberellin A26 (GA26), m.p. 254-257", formed a monomethyl ester (II), m.p. 207
Extracts of immature seeds of Lupinus found to possess biological activities luteus have been similar to the gibberellins (l-4). It was suggested from the chromatographic behavior and the characteristics of infrared spectra that the active principles were different from Cl9 gibberellins (5). We wish
The biosynthetic steps from gibberellin A12-aldehyde (GA12-aldehyde) to C19-GAs were studied by means of a cell-free system from the embryos of immature Phaseolus vulgaris seeds. Stable-isotope-labeled GAs were used as substrates and the products were identified by gas chromatography-mass spectromet
