Los metabolitos secundarios se identificaron mediante fitoquímico incluyó la cuantificación fenoles totales (TPC), flavonoides (TFC) antocianinas (TAC). extracto ...

Purpose: Various parts of Moringa oleifera Lam. (Moringaceae) are used in traditional systems medicine. This study investigates the antimicrobial activity crude aqueous extract and polyphenol enriched fractions M. leaves at flowering stage against microbial strains causing oral wound infections. Methods: Polyphenol (hydroalcoholic extract, methanol fresh dry decoction) were prepared using four ...

This study monitored changes in chlorophyll fluorescence (CF), growth parameters, soil moisture content, phytochemical content (proline, ascorbic acid, chlorophyll, total phenol (TPC), and flavonoid (TFC)), antioxidant activities 12-day-old lettuce (Lactuca sativa L.) seedlings grown under drought stress (no irrigation) control (well irrigated) treatments controlled conditions for eight days. M...

Jackfruit (Artocarpus heterophyllus Lam.) is a fruit of tropical and subtropical zones the world, an important source phytochemicals (phenolic acids, flavonoids tannins). Several studies have associated with antioxidant antimicrobial properties. The objective this work was to analyze polyphenolic content, antifungal properties jackfruit extracts on phytopathogenic fungi. Two phenolic different ...

in the present study, we have reported the total phenolic content, total flavonoid content, antioxidant and antimicrobial activity of aerial parts of salvia leriifolia extracts and fractions. methanolic, n-hexane, chloroform, and ethyl acetate extracts were screened to analysis their antioxidant activities by four complementary test systems, namely dpph free radical scavenging activity (rsa), t...

The growing demand for lettuce has prompted the need higher quality standards. Consequently, researchers have focused their efforts on identifying cultural management strategies that can enhance synthesis of antioxidant compounds, leading to improved functional properties lettuce. In this regard, two experiments were conducted hydroponically grown Lollo Bionda ‘Levistro’ and Rosso ‘Carmoli’ let...

Background. Dodonaea angustifolia is a known medicinal plant across East Arica. The flower of D. not well investigated in terms phytochemistry and biological activities. This study aims to investigate the presence flavonoids phenolic acids its antioxidant activity. Methods. Preliminary phytochemical screening was carried out using standard protocols. Antioxidant activity evaluation DPPH assay t...

Pineapple, with its attractive sensorial and nutritional characteristics, is the most traded tropical fruit worldwide. However, due to high-water content (85–92 w.b %), it highly perishable, therefore, postharvest loss of this a global concern. Drying an important preservation technique increase self-life preserve essential vitamins, minerals, fiber, carbohydrate, antioxidant properties. In stu...

This study evaluated unripe fruits of ten apple cultivars removed during fruit thinning for their antioxidant activity and mineral content. The were collected from Chuncheon Jeongseon located at Gangwon-Do Korea. Antioxidant activities such as total phenolic content (TPC), flavonoid (TFC), DPPH (2,2-diphenyl-1-picrylhydrazyl) activity, FRAP (Ferric reducing power), vitamin C contents measured. ...
