실험 절차

(S)-(+)-Abscisic acid (2.64 g of 95% purity) was suspended in 15 mL of deionized water containing 50 mg of Tween 20. One quarter of the theoretical amount of potassium hydroxide (250 microL of 10.0 molar aqueous solution) was added. The remainder of the neutralization was then carried out with concentrated aqueous ammonia solution, to give a clear solution of pH 7.1. Preservative (63 mg of potassium sorbate) was added, and it quickly dissolved. The solution was made up to 25 mL final volume to give a 10% by weight aqueous composition of abscisic acid as a mixture of the ammonium and potassium salts.
