OBJECTIVE To investigate the protective effect of purple sweet potato flavonoids (PSPF) on CCl4-induced acute liver injury in mice. METHODS Sixty mice were randomly divided into six groups (n=10 in each): blank group, model group, PSPF groups (400 mg*kg(-1), 200 mg*kg-1 and 100 mg*kg(-1)) and

Sweet potato is one of the oldest crops cultivated in Mexico, and Mesoamerica is considered as a region with the greatest diversity of this species. Therefore, the present study focused on the evaluation of biologically active compounds, such as caffeoylquinic acid derivatives and flavonoid

This work reports the development and application of a multi-compound analysis method for the determination of 17 flavonoids and polyphenols in sweet potato leaves. Samples were processed by microwave-enhanced accelerated solvent extraction under low pressure at 120 °C for 10 min. Salting-out

Flavonoid 3'-hydroxylase (F3'H: EC 1.14.13.21) is an important enzyme which determines the hydroxylation pattern of anthocyanins. In this study, the full-length cDNA and genomic DNA of F3'H were isolated and characterized from the purple-fleshed sweet potato (Ipomoea batatas). IbF3''H was 1,789 bp

The potato P locus is required for the production of blue/purple anthocyanin pigments in any tissue of the potato plant such as tubers, flowers, or stems. We have previously reported, based on RFLP mapping in tomato, that the gene coding for the anthocyanin biosynthetic enzyme flavonoid

To study the diversity and cultivar-specific of phytochemicals in sweet potato, Liquid Chromatography-Electrospray Ionization-Mass Spectrometry was used to analyze the metabolic profiles of five sweet potato cultivars exhibiting different flesh colors: purple, yellow/orange, and white. A total of

OBJECTIVE To investigate the effects of purple sweet potato flavonoids (PSPF) on blood glucose and lipids levels in diabetic rats. METHODS Diabetes was induced by intraperitoneal injection of streptozotocin (STZ, 65 mg.kg(-1)) in rats. The changes of fasting blood glucose and lipids levels in serum

Anthocyanin content of potato tubers is a trait that is attracting increasing attention as the potential nutritional benefits of this class of compound become apparent. However, our understanding of potato tuber anthocyanin accumulation is not complete. The aim of this study was to use a potato

In anthocyanin biosynthesis, UDP-glucose: anthocyanidin 3-O-glucosyltransferase (UFGT) catalyzes the transfer of the glucosyl moiety from UDP-glucose to the 3-hydroxyl group of anthocyanidins, producing the first stable anthocyanins. The full-length cDNA of UFGT (designated as StUFGT) was isolated

Late blight caused by Phytophthora infestans is a devastating disease affecting potato production worldwide. The quantitative resistance is durable, but the underlying molecular and biochemical mechanisms are poorly understood, limiting its application in breeding. Integrated transcriptomics and

This paper reports on morphophysiological and biochemical characteristics of control and potato plants (Solarium tuberosum L., Skoroplodnyi cultivar) transformed with the Δ12 acyl-lipid desaturase gene (desA) grown long-term in vitro. The transformed plants showed faster growth and faster

Late blight is a serious economic threat to potato crop, sometimes leading to complete crop loss. The resistance in potato to late blight can be qualitative or quantitative in nature. Qualitative resistance is not durable. Though quantitative resistance is durable, the breeding is challenging due to
