“…Medically, it has been reported that saponin is used in hypercholesterolaemia, hyperglycaemia, antioxidant, anti-cancer, anti-inflammatory and weight loss, etc, [46]. Saponin also has anti carcinogenic agents, immune modulations activity, cholesterol lowering activity and anti-fungal properties [47]. The alkaloid in red soko was lower (4.58±0.03 ppm) than green soko (5.49±0.02 ppm).…”

Medicinal plants are indispensable sources of bioactive compounds and have proved to be stalwart ingredients for a wide range of applications. The potency of five different solvents in extracting bioactive constituents; qualitative and quantitative determination of phytochemicals of red soko and green soko were studied. The plant were cut into smaller pieces, air-dried, ground into powdery sample, sieved with 40 mm mesh size and properly labelled. Each sample was extracted using five different solvents (acetone, chloroform, ethyl acetate, methanol and water) at ratio 1: 10 for 72 h. Each solvent extract was screened for nine phytochemicals (flavonoid, carotenoid, phenol, oxalate, tannin, saponin, alkaloid, phytate and ascorbic acid). It was observed that the plant extract contained seven phytochemicals in both red and green soko. The highest extractive values and qualitative screening of phytochemicals in red soko and green soko were obtained in water and methanol extracts. Quantitative phytochemical analysis showed that there was higher content of saponin, phytate and ascorbic acid in the two vegetables. Red soko contained lower ascorbic acid, saponin, total phenol, total carotenoid, alkaloid and flavonoid than green soko while green soko had lower phytate and tannin than red soko. There was no significant difference (P˂0.05) in flavonoids, total carotenoid and alkaloid contents in red soko and in green soko there was no significant difference (P ˂0.05) in total carotenoid and alkaloid contents.

“…High concentrations of saponin may impart a bitter taste, a major limiting factor to its use. However, saponins have been shown to also possess anticarcinogenic properties, immune modulation activities, active in the regulation of cell proliferation and cholesterol-lowering activity (Seigler, 1998).…”

Purpose Several factors may play critical roles in alterations to product quality during storage of hog plum juice. This study aims to evaluate variations to physicochemical, antioxidant, anti-nutritional properties and microbial stability of hog plum juice during storage. Design/methodology/approach Juice was produced from hog plum fruits and stored for eight weeks at refrigerated and ambient conditions. Physicochemical, antioxidant properties, antinutritional factors and microbial properties of juices were determined using standard procedures Findings Degradation of ascorbic acid was higher in juices stored at ambient conditions (64.4%) compared to those stored by refrigeration (44.4%). Trends were similar for total phenolic, total flavonoid and total carotenoid contents. Total phenolic, total carotenoid and lycopene contents of fresh juice were 3.9 mg GAE/mL, 4.0 mg/mL and 1.3 mg/mL, which were not significantly different (at p = 0.08, 0.07 and 0.08, respectively) from the values at two weeks of storage at refrigerated conditions (3.9 mg GAE/mL, 3.9 mg/mL and 1.3 mg/mL). A sharp decrease of more than 40% (p = 0.02) in lycopene was recorded after four weeks, irrespective of storage temperature. Pasteurized hog plum juice showed no microbial growth until after four weeks of refrigerated storage when 1 CFU/mL each of bacterial and fungal growth were recorded. The juices, however, showed higher susceptibility to fungal growth as storage period increased. Research limitations/implications Other variables not considered in this study such as nature of packaging materials may have significantly contributed to the observed data set. Further studies may, therefore, widen the scope of discussion to evaluate the associated relationship of these variables. Hog plum juice retained a considerable amount of bioactive components during refrigerated storage, which makes it a viable nutraceutical drink with industrial potentials and possible positive health implications for consumers. Practical implications This study provides new information that support the possible classification and use of hog plum juice as a safe functional beverage for human consumption. Originality/value Although the effect of storage temperature was significant in most of the properties studied, storage duration seems to have a greater influence on the stability of quality parameters during the storage of hog plum juice.

“…Anthocyanin is a key pigment in plants and attracting more interest from researchers due to its extensive and wide range of color, prominent beneficial health effect, and higher antioxidant activities. They are also involved in antimicrobial activity and protect the cells from intensive light damage by absorbing blue and ultraviolet light ( Seigler, 1998 ). Insufficient light and nutrient availability decreased the anthocyanin contents in fruits ( Youdim et al, 2002 ; Ohashi-Kaneko et al, 2007 ).…”

Identification and Comprehensive Genome-Wide Analysis of Glutathione S-Transferase Gene Family in Sweet Cherry (Prunus avium) and Their Expression Profiling Reveals a Likely Role in Anthocyanin Accumulation

Glutathione S-transferases (GSTs) in plants are multipurpose enzymes that are involved in growth and development and anthocyanins transportation. However, members of the GST gene family were not identified in sweet cherry (Prunus avium). To identify the GST genes in sweet cherry, a genome-wide analysis was conducted. In this study, we identified 67 GST genes in P. avium genome and nomenclature according to chromosomal distribution. Phylogenetic tree analysis revealed that PavGST genes were classified into seven chief subfamily: TCHQD, Theta, Phi, Zeta, Lambda, DHAR, and Tau. The majority of the PavGST genes had a relatively well-maintained exon–intron and motif arrangement within the same group, according to gene structure and motif analyses. Gene structure (introns-exons) and conserved motif analysis revealed that the majority of the PavGST genes showed a relatively well-maintained motif and exons–introns configuration within the same group. The chromosomal localization, GO enrichment annotation, subcellular localization, syntenic relationship, Ka/Ks analysis, and molecular characteristics were accomplished using various bioinformatics tools. Mode of gene duplication showed that dispersed duplication might play a key role in the expansion of PavGST gene family. Promoter regions of PavGST genes contain numerous cis-regulatory components, which are involved in multiple stress responses, such as abiotic stress and phytohormones responsive factors. Furthermore, the expression profile of sweet cherry PavGSTs showed significant results under LED treatment. Our findings provide the groundwork for future research into induced LED anthocyanin and antioxidants deposition in sweet cherries.
