Methods are given for the quantitation of the plant stress hormone, abscisic acid (ABA), and its two metabolic precursors, ketone and enolate, that are applicable to all species tested so far. The plant extract is homogenized at neutral pH, hexane-soluble neutrals are extracted and discarded, and th

The use of small columns containing charcoal and cellulose for the purification of abscisic acid and its metabolites from ptant extracts is described. These columns have high capacity and the sample processing time is short. The efficiencies of recovery of abscisic acid, abscisic acid glucose ester,
## Abstract The methods normally employed for the isolation of pure methyl oleate, linoleate, and Ξ±βlinolenate from appropriate natural sources are reviewed and simple procedures for isolating these esters are recommended. Evening Primrose Oil (__Oenothera biennis__) is a particularly useful source
