Phenolic biosynthesis during grain development in wheat: changes in phenylalanine ammonia-lyase activity and soluble phenolic content
Changes in phenylalanine ammonia lyase (PAL) activity and the total phenolic content of several wheat cultivars have been monitored during grain development. PAL activity was maximal during the early… Expand

We have purified a novel alliinase (EC 18.104.22.168) from roots of onion (Allium cepa L.). Two isoforms with alliinase activity (I and II) were separated by concanavalin A-Sepharose and had molecular… Expand
Between and within field variability of New Zealand indigenous flower visitors to onions.
In New Zealand, few studies have documented the occurrence of indigenous fl ower visitors within crops. A fi ve-year survey is examining the distribution, diversity and abundance of fl ower visitors… Expand
Spectrophotometric assay and electrophoretic detection of trans-feruloyl esterase activity.
Wheat bran cell walls were subjected to mild acid hydrolysis and the major phenolic product was purified and identified as 5-O-(trans-feruloyl)-arabinofuranose. Sensitive continuous and stopped,… Expand
Small flower-visiting arthropods in New Zealand pak choi fields
Flower-visiting small arthropods (body length <3 mm) that may vector pollen can be carried via air currents over long distances. Therefore, assessing their diversity, abundance and distribution… Expand
Purification and cloning of a gamma-glutamyl transpeptidase from onion (Allium cepa).
Gamma-glutamyl transpeptidase (E.C. 22.214.171.124; GGT) catalyses hydrolysis of gamma-glutamyl linkages in gamma-glutamyl peptides and transfer of the gamma-glutamyl group to amino acids and peptides.… Expand
Medical services at a music festival.
A three-day open air musical festival attended by approximately 20 000 people was held at Ngaruawahia in January 1973. A medical service was provided and staffed mainly by medical students, nurses… Expand
The effect of naloxone, morphine, and an enkephalin analogue on cholecystokinin octapeptide-stimulated gallbladder emptying.
Phenolic biosynthesis during grain development in wheat (Triticum aestivum L.) III. Changes in hydroxycinnamic acids during grain development
Changes in bound and soluble hydroxycinnamic acids have been investigated during the development of wheat grain. Analysis by HPLC revealed that the level of trans -ferulic acid decreased in the… Expand
Identification of the constituent flavanoid units in sainfoin proanthocyanidins by reversed-phase high-performance liquid chromatography
Abstract A rapid and sensitive method for the separation and identification of flavan-3-ols and their phoroglucinol adducts using reversed-phase high-performance liquid chromatography is reported.… Expand
