Versuchsvorschrift

(S)-(+)-Abscisic acid (2.64 g of 95% purity) was suspended in 15 mL of deionized water containing 50 mg of Tween 20. An aqueous solution of trimethylamine (1.5 mL of 6.6M concentration) was added, which caused most of the abscisic acid to dissolve. The remainder of the neutralization was then carried out by careful dropwise addition of the aqueous trimethylamine, to give a clear solution of pH 6.8. 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 trimethylammonium salt.
