Martynia annua L. is a well-known small herbaceous annual plant in Ayurveda as kakanasika, which is being used in Indian traditional medicines for epilepsy, inflammation and tuberculosis. This weed has been known to possess anthelmintic, analgesic, antipyretic, antibacterial, anti-convulsant, antifertility, antinociceptive, antioxidant, CNS depressant and wound healing activity. A wide range of...

The aim of the research was to analyse the weaknesses of the pH differential method for strawberry anthocyanin determination. The work is based on practical experiments with 12 strawberry cultivars and on analysis of published papers. We used following molar absorption coefficients ( values): 26900 and 29600 M cm for cyanidin 3 glycoside (C3g) and 15600, 22400, 27300 and 36000 M cm for pelargon...

Plant polyphenolics continue to be the focus of attention with regard to their putative impact on human health. An increasing and ageing human population means that the focus on nutrition and nutritional enhancement or optimisation of our foodstuffs is paramount. Using the raspberry as a model, we have shown how modern metabolic profiling approaches can be used to identify the changes in the le...

Anthocyanins, Flavonoids, Chalcone Synthase, Genetic Control, Matthiola incana Chalcone synthase activity was demonstrated in enzyme preparations from flowers of defined genotypes of Matthiola incana (stock). The product formed from 4-coumaroyl-CoA and malonylCoA was naringenin and not the isomeric chalcone, because chalcone isomerase was also present in the reaction mixture. Chalcone synthase ...

Qualitative and quantitative high performance liquid chromatography with diode array detection (HPLC-DAD) was performed to characterize the presence of phenolic compounds in Andean purple corn. Phenolic compounds were analyzed by separating them in two main fractions: a water fraction (WF) and an ethyl acetate fraction (EAF). The WF rich in anthocyanins revealed the presence of cyanidin-3-gluco...

By-products obtained from winemaking processes still contain large amounts of phenolic compounds, especially phenolic acids, flavanols, flavonols, stilbenes, and flavonoids. Enzymatic hydrolysis was used for determination and characterization of phenolic acids, flavanols, flavonols, and stilbenes. Characterization of the flavonoids was achieved using acid hydrolysis with 0.1% hydrochloric acid....

Yan73 is a "teinturier" red wine variety cultivated in China and used in winemaking to strengthen red wine color. Here, the anthocyanin profile in both the skin and pulp of this grape variety was analyzed by HPLC-MS. The results showed that 18 anthocyanins were detected in both the skin and the pulp, and pelargonidin-3-O-glucoside, an anthocyanin compound hardly detected in most other Vitis vin...

Anthocyanins are flavonoid-derived compounds that can reduce blood pressure. This study aims to determine the affinity value of compound bind Angiotensin Converting Enzyme (ACE) and II type 1 Receptor (AT1R) distance shape bond occurs. The results anthocyanin-derived Delphinidin, Petunidin, Malvidin, Cyanidin, Peonidin, Pelargonidin have anti-hypertensive potential through Renin Aldosterone (RA...

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...

A new iridoid glucoside, sesinoside (1), was isolated from the seedlings of Sesamum indicum. The structure of 1 was elucidated by spectroscopic analyses and by methanolysis of 1, which produced the known compounds, phlorigidosides C (2) and (6Z)-foliamenthic acid methyl ester (3). This is the first report of an iridoid glucoside with 3.
