## Abstract High performance liquid chromatography‐mass spectrometry using a thermospray interface and discharge ionisation has been conducted on a group of plant phenolic standards and on a wheat straw acid hydrolysate. Protonated molecules, [M + H]^+^, were observed for the phenolic standards and
In a previous paper(l) we described conditions for the gas-liquid chromatography (g.1.c. or g.c.) of gibberellin methyl esters and their trimethylsilyl (T.M.S.) ethers. Application of these g.1.c. methods to a crude acid extract, obtained from immature seed
