Crude ethanol extracts of leaves of Croton (Euphorbiaceae) species (C. hemiargyreus var. gymnodiscus, C. hemiargyreus var. hemiargyreus and C. echinocarpus) were analysed using on-column injection high temperature gas chromatography coupled with mass spectrometry. Several isoquinoline alkaloids were

β¦ Synopsis
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

An extract from 6000 dark-grown Phaseolus coccineus seedlings was purified by countercurrent distribution and G-10 Sephadex followed by gradient elution from a silicic acid partition column with increasing amounts of ethyl actetate in n-hexane. 25 fractions were collected and tested with the barley-
We have recently dercribed (1) the isolation of the new gibberellin Al7 (I, R-C02H) from imrrclture seed of Pbaseolur multiflorua and from its close relatioanhip to Bamboo gibberellin (I, R-CRO) (2) we anticipated the co-occurrence of theme two gibberellins in P. multiflonaa and Phylloatachyr edulir
