Soursop fruit has been used in folklore for the management of type-2 diabetes and hypertension with limited information on the scientific backing. This study investigated the effects of aqueous extracts (1 : 100 w/v) of Soursop fruit part (pericarp, pulp, and seed) on key enzymes linked to type-2 diabetes (α-amylase and α-glucosidase) and hypertension [angiotensin-I converting enzyme (ACE)]. Ra...

Three native Turkish medicinal and aromatic plants (Artemisia absinthum, Artemisia santonicum and Saponaria officinalis) were investigated to analyze their antioxidant activity, total phenolic content and antimicrobial activity. Their total antioxidant activity was determined by using a β-carotene bleaching assay and their antimicrobial activity was determined by utilizing an agar disc diffusio...

Thunbergia laurifolia Lindl. or Rang Chuet (RC) is widely described in Thai traditional medicine for protection against dietary and environmental toxicants with little substantiation. To better access the potential of RC as a medicinal plant, extracts were prepared by infusion with water, ethanol and acetone. Antioxidant activities and total phenolic content of RC extracts were evaluated using ...

The aim of this study was to investigate the antioxidant activity of the methanolic extracts of Filipendula hexapetala Gilib. aerial parts (FHA) and roots (FHR) and their potential in different model systems, as well as antimicrobial activity. According to this, a number of assays were employed to evaluate the antioxidant and antimicrobial potential of F. hexapetala extracts. In addition, the a...

In the present study, phenolic extracts and fractions from Canadian rowanberry (Sorbus aucuparia) and crabapple (Malus baccata) were screened for antioxidant activity using DPPH radical scavenging activity, and β-carotene bleaching assays. Furthermore, rapeseed oil was supplemented with extracts/fractions and performance was assessed during accelerated storage at 65°C, under Rancimat at 120°C, ...

total phenolic contents (tpc) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of artemisia biennis willd were measured in this work. the antioxidant activity was investigated by three different methods: β-carotene bleaching (bcb) test, 2,2-diphenyl-1-picrylhydrazyl (dpph) radical scavenging method and ferrous ion chelating (fic) assay. amo...

Hymenocallis littoralis has allelochemical importance such as defensive compounds, insect repellents, attractants, and their role in ecological balance. Antioxidant activities of Hymenocallis littoralis bulb, anther, flower, stem, leaves and root methanolic extracts were evaluated using Ferric Reducing Antioxdiant Power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH), total phenolic and flavonoid ...

Thirteen Malaysian plants; Artocarpus champeden, Azadirachta indica, Fragaria x ananassa, Garcinia mangostana, Lawsonia inermis, Mangifera indica, Nephelium lappaceum, Nephelium mutobile, Peltophorum pterocarpum, Psidium guajava and Syzygium aqueum, selected for their use in traditional medicine, were subjected to a variety of assays. Antioxidant capability, total phenolic content, elemental co...

   Phenolic extracts of canola (Brassica napuse L.) contains substances that inhibited the germination and seedling growth of soybean (Glycin max L.). These compounds also affect activity of some enzymes. Hear, we investigated the allelopathic effects of various canola plant parts on soybean germination, seedling growth, and biochemical aspects. Phenolic extract of canola shoot (including leaf,...
