This study aimed to evaluate the effects of seven stages (Lonicera caerulea berry juice, after enzymatic hydrolysis, sugar and acid adjustments, fermentation, deacidification, clarification ageing) in making Lonicera wine on anthocyanins antioxidant capacity were studied. The total anthocyanin content was determined by pH-differential method. composition measured HPLC-MS/MS. 1,1-diphenyl-2-picr...

UV radiation plays an important role not only in plant growth and development but also the accumulation of essential nutrients health-promoting phytochemicals plants. The main objective this study was to examine effects supplemental UV-A, UV-B, UV-AB on nutritional quality lettuce (Lactuca sativa, cv. red leaf “New Red Fire” green “Two Star”) tomato (Solanum lycopersicum L., BHN-589) grown a gr...

About 600 species of Passiflora are described around the world, which 120 native to Brazil. In present work, phytochemical compounds were analyzed by high-performance liquid chromatography, and antioxidant activities (AOX) measured in pulp P. edulis cincinnata species. The presented a higher bioactive content AOX when compared cincinnata. Citric malic acids main organic found. principal compone...

background: the genus lomatopodium fisch. & c.a.mey., belongs to apiaceae family and contains one herbaceous species growing wildly in iran. there are only a few papers about the chemical constituents of these plants. here, we focused on the isolation and identification of the main flavonoid glycosides and sterols from the aerial parts of l. staurophyllum, which has not been previously reported...

An enzyme in extracts of Aerobacter aerogenes was shown to catalyze the hydrolytic cleavage of cellobiose monophosphate (6-0-phosphoryl-b-D-ghtcopyranosyl-(1 --f 4)-D-gillcase) to yield equimolar amounts of D-glucose and D-glucose 6-phosphate. The enzyme was partially purified and characterized. In addition to cellobiose monophosphate, it catalyzed the cleavage of cellobiitol phosphate, arbutin...

It has been observed by Michaelis and Pechstein (1) and others, that a-methyl glucoside manifests a marked retarding influence on the hydrolysis of sucrose by invertase. The curves given in Fig. 1 represent the hydrolysis of a 10 per cent sucrose solution by invertase in the presence and absence of the glucoside. Nelson and Hitchcock (2) found that the hydrolysis of 10 per cent sucrose solution...
