Combined gas chromatography-selected ion monitoring (GC-SIM)analysis of a purified extract from seeds of Leucaena leucocephalashowed the presence of GA1, GA8, GA17, GA19, GA20, GA23, GA29and GA53. GA1, GA8 and GA29 were also found both as glucosylester-like and glucosyl ether-like conjugates, and GA20 as aglucosyl ester-like conjugate; these conjugates were analyzedas free GAs after enzyme hydrolysis. GA23 was shown to be themain free gibberellin in immature seeds (268 ng/seed), thoughits level drastically decreased during their maturation. GA1was the main free C19-gibbercllin and GA1 glucosyl ester-likeand glucosyl ether-like conjugates were found at the highestlevels in the seeds prior to maturation. Fluctuation of endogenouslevels of gibberellins is discussed in terms of seed development. (Received May 9, 1984; Accepted August 25, 1984) 相似文献
