Evaluation of -Glucosidase and -Amylase Inhibition in Thai Culinary Vegetables.

Diabetes management through dietary intervention has gained significant interest, particularly in the use of natural plant-based inhibitors of key enzymes involved in carbohydrate digestion. The objective of this study was to assess the inhibitory effects of ten Thai culinary vegetables on -glucosidase and -amylase, including Chinese chive (), holy basil (), star gooseberry (), galangal (), bamboo grass (), Turkey berry (), cassod tree (), dill ( L.), noni (), and pearl wattle ().

Influence of soil amendments on phytostabilization, localization and distribution of zinc and cadmium by marigold varieties.

Marigolds (Tagetes erecta L.) were evaluated for phytoremediation potential of cadmium (Cd) and zinc (Zn) as a function of amendment application to soil. Vermicompost (V), biodigestate (Bi), and combined V + Bi (VBi) were used as soil amendments in Zn and Cd co-contaminated soils.

Wheat bran particle size influence on phytochemical extractability and antioxidant properties.

It is unknown if particle size plays a role in extracting health promoting compounds in wheat bran because the extraction of antioxidant and phenolic compounds with particle size reduction has not been well documented. In this study, unmilled whole bran (coarse treatment) was compared to whole bran milled to medium and fine treatments from the same wheat bran. Antioxidant properties (capacity, ability, power), carotenoids and phenolic compounds (phenolic acids, flavonoids, anthocyanins) were measured and compared.

Phytochemicals and antioxidant activity of different fruit fractions (peel, pulp, aril and seed) of Thai gac (Momordica cochinchinensis Spreng).

Three fractions (peel, pulp and aril) of gac fruit (Momordica cochinchinensis Spreng) were investigated for their phytochemicals (lycopene, beta-carotene, lutein and phenolic compounds) and their antioxidant activity. The results showed that the aril had the highest contents for both lycopene and beta-carotene, whilst peel (yellow) contained the highest amount of lutein. Two major phenolic acid groups: hydroxybenzoic acids and hydroxycinnamic were identified and quantified.

Phenolic contents and antioxidant activities of bitter gourd (Momordica charantia L.) leaf, stem and fruit fraction extracts in vitro.

Bitter gourd (Momordica charantia L.) has long been regarded as a food and medicinal plant. We investigated the antioxidant activity of the water extract of leaf, stem and fruit fractions by several in vitro systems of assay, namely DPPH radical-scavenging activity, hydroxyl radical-scavenging activity, β-carotene-linoleate bleaching assay, ferric reducing/antioxidant power (FRAP) assay and total antioxidant capacity.
