Abstract

Immature seeds of loquat (Eriobotrya japonica) were collected from developing fruits 90 days after full bloom. After purifying the acidic ethyl acetate-soluble fraction by several chromatographic procedures, gibberellin fractions were surveyed by combined gas-liquid chromatography/mass spectrometry. Consequently, GA9, GA15,GA24, GA35, and GA50 were identified. Additionally, six GA-like substances were detected, and two were determined to be new GAs, GA80 (11β-hydroxy-GA7), and GA84 (11β-hydroxy-GA9). Based on these results, an early-11-hydroxylation biosynthetic pathway in the seed of loquat is suggested.
