Twenty cultivars of Lens culinaris Medik. were grown over 5 years in 18 provinces of Spain. Saponin content in the harvested seed ranged from 654 to 1269 mg kg−1. Two saponins were detected and identified as soyasaponins I and VI. Changes observed

On the basis of spectroscopic and chemical methods, the structures of two new triterpenoid glycosides, transsylvanoside E and F, isolated from Cephalaria transsylvanica have been established as 3-O-[beta-D-xylopyranosyl (1-->3)-alpha-L-rhamnopyranosy

Treatment of Saccharomyces cerevisiae with the morpholine fungicide fenpropimorph was examined using both a wild-type and a mutant strain (erg2) defective in sterol delta 8-->7-isomerase. No resistance to fenpropimorph was observed in the mutant stra

It is shown that both electrospray and fast atom bombardment mass spectrometry provide excellent negative-ion mass spectra of the anionic esters of boric, boronic and borinic acids. For electrospray, contact of the esters with water causes some hydro

Some novel homochiral derivatizing agents for the determination of enantiomeric composition of chiral alcohols have been synthesised. The reactions of the reagents with alkan-2-ols and the gas chromatographic behaviour of the resulting diastereoisome
