endogenous gibberellins in immature seeds of Prunus persica were analyzed by gas chromatography-mass spectrometry. Eleven known gibberellins, GA(3), GA(9), GA(17), GA(19), GA(30), GA(44), GA(61), GA(63), GA(87), GA(95) and GA(97) were identified. Additionally, several hitherto unknown gibberellins were detected and their putative structures were verified by synthesis of the authentic gibberellins. These
用气相色谱-质谱法分析了桃未成熟种子中的内源赤霉素。十一种已知的赤霉素,GA(3)、GA(9)、GA(17)、GA(19)、GA(30)、GA(44)、GA(61)、GA(63)、GA(87)、GA (95) 和 GA(97) 被确定。此外,还检测到了几种迄今为止未知的赤霉素,并通过合成真正的赤霉素来验证其推定的结构。然后为这些赤霉素分配了一些简单的数字,例如 1alpha-羟基 GA(20) (GA(118))、1alpha-羟基 GA(9) (GA(119))、1,2-didehydro GA(9) (GA(120) ))、1,2-二氢GA(70) (GA(121))、1,2-二氢GA(69) (GA(122))和1,2-二氢GA(77) (GA(126)) . GA(118) 和 GA(119) 是最早从高等植物中鉴定出的 1alpha-羟基赤霉素。1,2-二脱氢赤霉素的上述特征表明
