This study focused on total phenolic content (TPC) and antioxidant and antibacterial activities of the leaves and stems of Passiflora quadrangularis, P. maliformis, and P. edulis extracted using three solvents: petroleum ether, acetone, and methanol. The maximum extraction yields of antioxidant components from the leaves and stems were isolated using methanol extracts of P. edulis (24.28%) and ...

Natural plant extracts / products have the potential as safe alternatives for chemical fungicides in plant disease management. Methanol and pure methanol: water (50:50 v/v) extracts of peppermint, lavandula, eucalyptus, datura and nettle were screened for their antifungal activity against Alternaria sesami, the causal agent of Alternaria leaf spot of sesame at 5, 10 and 15% concentrations in Sh...

Six different crude extracts were obtained from the skin, pulp and whole fruit freeze-dried samples of Baccaurea angulata, an underutilized tropical fruit from Borneo Island of Malaysia. The effect of solvents on; total phenolic contents, total flavonoid contents, total carotene contents, free radical scavenging activities, phosphatidylcholine peroxidation inhibition activities and qualitative–...

The antioxidant properties of Galium verum L. (Lady’s Bedstraw) and Tragopogon pratensis subsp. pratensis (Goat’s beard) methanol extracts, from localities in Serbia were evaluated, through determination of total phenolics and flavonoids content, as well as DPPH • (1,1-diphenyl-2-picrylhydrazyl) radical scavenging, ABTS •+ (2,2-azinobis-(3ethylbenzthiazoline-6-sulfonic acid) radical cation deco...

objective: dracocephalum kotschyi (lamiaceae family) has been usedin traditional medicine for stomach and liver disorders, headache and congestion. in the present study, we have investigated phytochemical properties and antioxidant activities of dichloromethane, ethyl acetate and methanol extracts of d.kotschyi. material and methods: antioxidant activities of extracts were evaluated using the i...

Total flavonoids contents and antibacterial activity of the extracts from the aerial parts of two Labiateae species, Nepeta menthoides Boiss. & Buhse and Thymus trautvetteri Klokov & Desj.-Shost. were determined. Quantitative determination of flavonoid contents was calculated in terms of quercetin equivalent in various extracts (50% methanol, chloroform and distilled water) by AlCl3 colorimetri...

Many medicinal plants were with a long history of use in folk medicine against a variety of diseases. Recently, many researchers have taken a great interest on medicinal plants for their phytochemical constituents and biological activities including antimicrobial activity. The pet ether, chloroform, ethyl acetate and methanol extracts of Acmella paniculata were tested for antimicrobial activity...

The antioxidative, antimicrobial and antibiofilm potentials of acetone, ethyl acetate and methanol extracts of lichen species Platismatia glauca and Pseudevernia furfuracea were evaluated. The phytochemical analysis by GC, GC/MS and NMR revealed caperatic acid, atraric acid, atranorin and chloroatranorin as the predominant compounds in Platismatia glauca. Atraric acid, olivetoric acid, atranori...

ArisaemajacquemontiiBlume (Araceae) is reputed for its physiological properties in the folk medicine system and used in Chinese herbal medicine as anti-convulsant. Methanolic extracts of roots and fruits, the chloroform extracts of roots and shoots of ArisaemajacquemontiiBlume were investigated for immunomodulatory,antileishmanialand phytotixic activities. Immunomodulatory activitywas investiga...
