In this study, caffeic acid (CA) and its three derivatives including 3-caffeoylquinic acid (3-CQA, neochlorogenic acid), 4-caffeoylquinic acid (4-CQA, cryptochlorogenic acid), and 5-caffeoylquinic acid (5-CQA, chlorogenic acid) were identified in Bupleurum chinense aerial parts using reverse-phase high-performance liquid chromatography (RP-HPLC) with photodiode array (PDA) detector, reference c...

In the present study, models were developed to estimate the altitudinal variation in secondary metabolite contents of Hypericum orientale growing wild in “Güldağı” mountain, Turkey. Aerial parts of flowering 30 individuals were collected at six different altitudes (500, 1150, 1650, 2100, 2720 and 3250 m). Actual secondary metabolite contents of plants were measured by High Performance Liquid Ch...

The present investigation has been carried out to determine the antioxidant activity of the methanolic extracts obtained from four cultivars of cowpea (Vigna unguiculata (L) Walp.) seeds. Phenolic compounds present in the extracts showed the antioxidant and antiradical properties when investigated using a linoleic acid peroxidation model, FRAP, ORAC and TRAP assays, as well as DPPH, hydroxyl, n...

China is an important centre of diversity for Prunus persica. In the present study, 17 Chinese peach cultivars were evaluated for phenolic content and antioxidant activity. Neochlorogenic acid (NCHA), chlorogenic acid (CHA), procyanidin B1 (B1), catechin (CAT), cyanidin-3-O-glucoside (C3G), quercetin-3-O-galactoside (Q3GAL), quercetin-3-O-glucoside (Q3GLU), quercetin-3-O-rutinoside (Q3R), and k...

This study investigated the effects and mechanism of actions neochlorogenic acid (3-caffeoylquinic acid; 3-CQA) on glucose lipid metabolism in rats fed a high fat-high fructose diet (HFFD). Male were HFFD (40 % lard 20 fructose) for 16 weeks. At 10th week, split into 3 groups: receiving distilled water (HFFD control group), 3-CQA 50 mg/kg metformin 200 once daily further 6 end treatment, fastin...

The aim of the experiment was to determine the content of selected phenolic compounds (3,4dihydroxybenzaldehyde, caffeic acid, chlorogenic acid, cryptochlorogenic acid, ferulic acid, gallic acid, neochlorogenic acid, p-coumaric acid, p-hydroxybenzaldehyde , p-hydroxybenzoic acid, protocatechuic acid, salicylic acid, sinapic acid, syringic acid, vanilic acid, vanilin, cinnamic acid) in eight kin...

Phenolic acids are thought to be beneficial for human health and responsible for vegetables' health-promoting properties. Free, conjugated, and bound phenolic acids of seven commonly consumed vegetables, including kidney bean, cow pea, snow pea, hyacinth bean, green soy bean, soybean sprouts and daylily, from the regions of Beijing, Hangzhou, and Guangzhou, were identified and quantified by ult...

To understand the metabolite dynamics and genetic regulatory mechanism of apricot shell, a typical endocarp, before after lignification are unknown, we investigated differences endocarp ‘Youyi,’ popular kernel-using cultivar, using ultra-performance liquid chromatography tandem mass spectrometry strategy. The thickness increased rapidly from 8 to 37 days flowering (DAF) lignin deposition began ...
