Buckwheat has tremendous nutraceutical potential owing to its rutin and quercetin content. The aim of this study was to optimise and validate an analytical method for separating and quantifying these two flavonoids from it. Factors, such as range, linearity, precision, accuracy, limit of detection and limit of quantification, were evaluated for the two compounds using high performance liquid chromatography. On the basis of resolution and symmetry, mobile phase consisting of methanol and methanol:water:acetic acid in the ratio of (100:150:5), flow rate 1.3 ml/min and column temperature 30 °C were found to be optimal analytical conditions. Calibration curves exhibited good linearity with correlation coefficient of 0.995 & 0.9907 over the range 60-180 μg/ml & 2-10 μg/ml for rutin and quercetin respectively. LOD and LOQ values for rutin and quercetin were 6.36, 0.58 and 19.28, 1.77 μg/ml respectively. Recovery values of 96-100.8% confirmed that the method was accurate for rutin and quercetin analysis. This validated method was successfully used to analyse rutin and quercetin in leaves and seeds of buckwheat plant.

Dried apricots are rich in a variety of polyphenols, which have anti-cancer activity. In this study, 949 phenolic substances were found by means of UPLC-MS/MS, mainly including 2',7-dihydroxy-3',4'-dimethoxyisoflavan, scopoletin, rutin, quercetin-3-O-robinobioside, and elaidolinolenic acid. The results indicated that dried apricot polyphenols (DAPs) could cause cell cycle arrest in the G0/G1 and G2/M phases by decreasing the cyclin D1, CDK4, cyclin B1, CDK1, and CDK6 levels in A549 human lung adenocarcinoma cells.

The study was carried out to assess the effect of the larch wooly adelgid Vallot (Hemiptera: Adelgidae) infestation on its secondary host, the European larch Mill. Morphology and anatomy of adelgid-infested needles, and content of defense phenolic compounds including individual flavonoids isorhamnetin, kaempferol, quercetin, rutin, catechin, epicatechin, apigenin, ampelopsin and taxifolin, were analyzed. The amount of total phenols in needles from adelgid-infested twigs of increased following the development of the population, from the end of April until the end of June.
