Study on Barley and Malt Polyphenoloxidase. I. Chromatography of Barley, Steeped Barley, and Malt Polyphenoloxidase
A comparative chromatography of polyphenoloxidase isolated from barley, steeped barley, and green malt was made. It consisted ofextraction, precipitation, ion-exchange chromatography, gel filtration, and electrofocusing. Polyphenoloxidase was resolved into a high-molecularweight enzyme and a low-molecular-weight one. The proportion of the two enzymes underwent variations during malting. An incr...
متن کاملNew benzophenone O-glucoside from Hypericum ellipticum.
Examination of the acetone extract of the aerial parts of Hypericum ellipticum afforded a new acetylated benzophenone glucoside (3'-O-beta-D-3",4",6"-triacetylglucopyranosyl-2,4,5',6-tetrahydroxybenzophenone) together with catechin and epicatechin. The structure of the benzophenone glucoside was determined by 2D NMR spectroscopic data. The compound inhibited the proliferation of CNS tumor cell ...
متن کاملBeta-amylase degradation by serine endoproteinases from green barley malt
Proteolytic degradation of barley proteins is examined in green (unkilned) malt and germinating seeds from Hordeum vulgare L. cv. Harrington. Zymographic analysis of the Harrington green malt extracts using commercial preparations of barley beta-amylase incorporated as a proteolytic substrate in 2-D SDS gels shows multiple proteolytic activities. A developmental study shows that the several gre...
متن کاملEgg Yolk Cholesterol of Hens Fed Barley Malt Rootlets
This study aimed to decrease the cholesterol content of egg yolk of laying hens through inclusion of barley malt rootlets in the diets. Forty-two, 54-week-old, Lohman laying hens were fed for a 12 weeks laying period on 3 iso-caloric and iso-nitrogenous diets contained 0 (control), 25.5 or 51.1g barley malt rootlets/kg. Inclusion of barley malt rootlets at 25.5 or 51.1g/kg diet significantly de...
متن کاملin vitro anti-hiv-1 activities of kaempferol and kaempferol-7-o-glucoside isolated from securigera securidaca
previously, we reported that the kaempferol and kaempferol-7- o -glucoside isolated from securigera securidaca showed potent anti-hsv activity. in the present study the anti-hiv-1 activities of kaempferol and kaempferol-7- o -glucoside are investigated at different concentrations (100, 50, 25 and 10 µg/ml) using hiv-1 p24 antigen kit. real-time polymerase chain reaction (rt-pcr) assay was also ...
