摘要: 采用甲醇︰乙酸乙酯︰甲酸 = 50︰50︰1 的混合液作为提取溶剂,可快速从草莓中提取ABA,
整个提取过程可在0.5 h 内完成,大大提高了ABA 提取效率。建立了一套适合ABA 分析的超高效液相色
谱分析体系,其流动相为甲醇︰乙腈︰0.1%甲酸 = 20︰10︰70,流速0.3 mL · min-1,检测波长265 nm,
柱温30 ℃,进样10 μL。利用建立的快速提取法及超高效液相色谱分析方法,测定了不同发育阶段草莓
果实(青果、白果、粉红果和红果)的ABA 含量,发现其呈上升趋势,至红果期ABA 含量达到最高。

Abstract: This study was carried out to look for an optimized method for extraction of endogenous
abscisic acid(ABA)from strawberry and for ultra performance liquid chromatography(UPLC)analysis.
A rapid extracting method that using Methanol-ethyl acetate-formic acid(50︰50︰1,v/v)as extracting
liquid was found out,which can extract ABA from strawberry in half an hour. An efficient UPLC analysis
method for ABA was also established,Chromatographic separation was carried out by reversed Phase
ACQUITY UPLC BEH C18 column and with Methanol︰acetonitrile︰0.1% formic acid(20︰10︰70)
isocratic elution program,at column temperature of 30 ℃,injection volume of 10 μL,flowrate of
0.3 mL · min-1,and wavelength at 265 nm. Applying the extracting and UPLC analysis method,we
evaluated the content of ABA in strawberry fruit at different developments and ripening stages. The result
showed that with developing and ripening,content of ABA in strawberry was increasing,and reached the
highest level at the red ripening stage.

Key words: strawberry, ABA, UPLC, extraction
