Age-dependent alteration in metabolism of vitamin B , neurotransmitters, and amino acids after 4'-O-methylpyridoxine administration in rats.

4'-O-methylpyridoxine (MPN), a recognized antivitamin B compound, is a potentially poisonous substance found in Ginkgo biloba L. In this work, the effects of MPN on the metabolism of vitamin B , neurotransmitters, and amino acids were compared in the plasma and brain of young and adult rats under various administration times. Results showed that the contents of MPN residues in the plasma and brain of young rats were 12.

In vivo toxicity assessment of 4'-O-methylpyridoxine from Ginkgo biloba seeds: Growth, hematology, metabolism, and oxidative parameters.

4'-O-methylpyridoxine (MPN), a recognized antivitamin B compound, is a potentially poisonous substance found in Ginkgo biloba seeds and leaves. In this work, the body weights, histopathological changes, plasma vitamin B (VB), biochemical parameters, oxidative stress responses, and amino acids of rats were investigated after intragastric administration of MPN for 15 days. Results showed that intragastric administration of 50 mg/kg BW MPN caused pathological changes in the brain and heart tissues of rats.

4'--methylpyridoxine: Preparation from Seeds and Cytotoxicity in GES-1 Cells.

seeds are wildly used in the food and medicine industry. It has been found that 4'--methylpyridoxine (MPN) is responsible for the poisoning caused by seeds. The objective of this study was to explore and optimize the extraction method of MPN from seeds, and investigate its toxic effect on human gastric epithelial cells (GES-1) and the potential related mechanisms.

Influence of packaging materials on postharvest physiology and texture of garlic cloves during refrigeration storage.

This study aims to investigate the postharvest physiology and texture of garlic cloves packaged in polyethylene terephthalate (PET), polyethylene (PE), aluminized kraft paper (AKP), single kraft paper (SKP), and mesh bag. Germination rate, electrical conductivity, respiration intensity, water content, and texture were determined during 180 d storage at -2 °C. Results showed that the germination of garlic cloves packaged in PET, PE, and AKP was effectively inhibited during storage.

Determination and Comparison of 4'- O-Methylpyridoxine Analogues in Ginkgo biloba Seeds at Different Growth Stages.

The antivitamin B, 4'- O-methylpyridoxine (MPN); its glucoside, 4'- O-methylpyridoxine-5'-glucoside (MPNG); and vitamin B compounds, including pyridoxal (PL), pyridoxamine, pyridoxine, pyridoxal-5'-phosphate (PLP), and pyridoxamine-5'-phosphate, exist in Ginkgo biloba seeds, which are widely used as food and medicine. This work aimed to determine the MPN analogues in G. biloba seeds at different growth stages in terms of cultivars and ages of trees.

Allergic identification for ginkgo kernel protein in guinea pigs.

L. can cause allergic reactions when consumed. In this paper, an allergy test to guinea pig was investigated.

Comparison of Phytochemicals and Antioxidant Capacity in Three Bean Varieties Grown in Central Malawi.

The aims of the current work were: (1) to study the influence of variety and geographical production area on the total phenolic content, total anthocyanin content, total flavonoid content, total carotenoid content and antioxidant activity in bean varieties (Dimeta, Napirira and Nanyati) from different growing areas in central Malawi, and (2) to evaluate the possibility of establishing a classification based on the geographical areas of the growing regions. A total of 47 bean samples were collected from Makowe, Mphathi, Chuma-Chitsala and Khulungira Zone. These four locations were segregated based on altitude, latitude and longitude.

Production of cordycepin and mycelia by submerged fermentation of Cordyceps militaris in mixture natural culture.

The submerged fermentation of Cordyceps militaris for cordycepin production and mycelial growth was investigated in this study. Three natural materials of brown rice paste (BRP), beerwort (B), and soybean meal juice (SMJ) were used for fermentation of C. militaris in shaking flasks.
