Saridas, Mehmet Ali;Ag am, Erdal;Akbas, Furkan Cihad;Akyildiz, Asiye;Paydas Kargi, Sevgi research published 《 Comparison of superior bred strawberry genotypes with popular cultivars in terms of fruit bioactive compounds during the wide harvest dates》, the research content is summarized as follows. Secondary compounds of fruit are among the essential concerns due to their pos. effects on human health. Many studies have attempted to improve these compounds by applying different genotype or cultivation practices such as irrigation and fertilization. This study aimed to find out the effect of different harvest dates on strawberry genotypes in terms of total phenolic (TP), total antioxidant activity (TAA), total monomeric anthocyanin (TMA), and some crucial individual phenolic compounds during the five-month growing season (Jan. – May periods) with one month intervals. Besides, superior bred lines (′33′, ′36′ and ′61′) were compared with widely grown cultivars (′Rubygem′, ′Festival′ and ′Fortuna′) under the Mediterranean climate conditions. Regarding the genotypes, it was observed that TMA, TP, TAA, (-) epicatechin, (-) epicatechin gallate, pelargonidin 3- glucoside (P3G), and pelargonidin 3- rutinoside (P3R) values were the highest values in the 33-bred line, while the 36-bred line standed out in terms of ferulic acid and cyanidin 3- glucoside (C3G). This study also has shown that the chlorogenic acid and sinapic acid contents of the 61-bred line were found in the highest level comparing with the others. Regarding the harvest date, fruit antioxidant activity, total phenolic compounds, and individual phenols such as gallic, syringic, ferulic, (-) epicatechin and ellagic acid were measured the highest in May-harvested fruits, whereas these values were observed at the lowest level in March, except for syringic and (-) epicatechin. On the other hand, rutin, quercetin, sinapic acid, chlorogenic and caffeic acids, and P3G and P3R levels of fruits were the highest in Apr., when it was the most intense harvest period in Mediterranean climate conditions. These observations indicated that these compounds could be increased by choosing the right genotype and suitable environmental conditions.
530-59-6, Sinapinic acid is a chemical compound that is the dihydroxybenzoic acid derivative of sinapic acid. It has been shown to have anti-inflammatory properties in vitro and in vivo. Sinapinic acid inhibits the activity of various enzymes, such as cyclooxygenase (COX), lipoxygenase (LOX), and 5-lipoxygenase-activating protein (FLAP). It also decreases levels of adhesion molecules and downregulates inflammatory response genes. Sinapinic acid has been shown to reduce inflammation by inhibiting the formation of proinflammatory mediators, such as prostaglandin E2 or leukotriene B4, in endothelial cells and mammary epithelial cells.
Sinapic acid is a phenylpropanoid hydroxycinnamic acid with diverse biological activities. Sinapic acid inhibits collagen-induced human platelet aggregation by up to 70% in vitro (IC50 = 1.03 mM). It scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; ) and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) free radicals with IC50 values of 8.3 and 5.4 μg/ml, respectively. Sinapic acid (200 μM) reduces colony formation of SW480 human colon carcinoma cells by 4-fold. It also inhibits colony formation of E. coli, S. enteritidis, and S. aureus on agar (MICs = 2.2, 2, and 1.8 mM, respectively). In vivo, sinapic acid (4 mg/kg, p.o.) increases the time spent in the open arms of the elevated plus maze by approximately 15% in mice, an effect that can be blocked by the GABAA receptor antagonists flumazenil and bicuculline. Sinapic acid is also commonly used as a matrix in protein mass spectrometry.
Sinapic acid analytical standard provided with w/w absolute assay, to be used for quantitative titration.
Sinapic acid is an hydroxycinnamic acid derivative that occurs naturally in Brassicaceae species.
cis-Sinapic acid, also known as cis-sinapate or synapitic acid, belongs to the class of organic compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. cis-Sinapic acid is considered to be a practically insoluble (in water) and relatively neutral molecule. Within the cell, cis-sinapic acid is primarily located in the cytoplasm. Outside of the human body, cis-sinapic acid can be found in common pea and pulses. This makes cis-sinapic acid a potential biomarker for the consumption of these food products.
Cis-sinapic acid is a 3-(4-hydroxy-3,5-dimethoxyphenyl)prop-2-enoic acid in which the double bond has cis-configuration. It has been isolated from the shoots of alfalfa. It has a role as a plant metabolite., Safety of 3,5-Dimethoxy-4-hydroxycinnamic acid
