BACKGROUND/OBJECTIVES In Asia, various medicinal plants have been used as the primary sources in the health care regimen for thousands of years. In recent decades, various studies have investigated the biological activity and potential medicinal value of the medicinal plants. In this study, 100 methanol extracts from 98 plant species were evaluated for their biological activities. MATERIALS/M...

Indonesia is known as one of the largest medicinal plant user countries in world. There are several plants that have potential medicine, such Jeluak (Microcos tomentosa) plant. The purpose this study was to determine antioxidant activity ethanolic extract Fruit tomentosa). ethanol obtained through maceration method. Antioxidant testing carried out by free radical scavenging method with 2,2-diph...

Lamiaceae herbs known for their culinary properties are a rich source of potentially health-beneficial antioxidant polyphenols. The objective of this investigation was to evaluate and prove the in vitro antioxidant activity of five different extracts of aerial parts of the plant Leucas aspera, belonging to the family Lamiaceae on different models namely the DPPH free radical scavenging assay, F...

Celastrus paniculatus is an Indian medicinal plant which has been used for thousands of years in the traditional Ayurvedic system of medicine. It is fast gaining importance in the primary healthcare systems as well as in herbal drug formulations. Oil obtained from the seeds of the plant is reported to be highly beneficial in stimulating intellect and sharpening the memory. It also acts as a pot...

Garcinia xanthochymus has been widely used in traditional Chinese medicine for expelling worms and removing food toxins. Bioassay-guided fractionation of an EtOAc-soluble extract of G. xanthochymus stem bark led to the isolation of six new xanthones. Their structures were elucidated by spectroscopic methods, especially 2D-NMR techniques. Free-radical-scavenging activities of the isolated compou...

Antioxidant activity of polar methanolic extract of aerial parts of Ocimum sanctum using multiple screens was studied. Various concentrations of the standardized extract were examined for the free radical scavenging activity, superoxide radical scavenging potential and effect on nitric oxide production in RAW 264.7 mouse monocytes cell line. The results indicated that the O. sanctum extract has...

the present study was designed to explore the flavonoid contents and the radical scavenging activities of 50% ethanol extracts of leaves, stems, rachis and roots of dryopteris erythrosora. the total flavonoid contents in various parts were determined as: stems > roots > rachis > leaves. all extracts from different parts of d. erythrosora showed strong bioactivities. the dpph free radical scaven...

Being encouraged by the results of qualitative analysis followed by quantification studies of antioxidants found in various extracts of Cyanotis fasciculata, the present study was designed to assess the free radical scavenging activity of 70% hydro alcoholic (AE) and methanolic extracts (ME) of this plant through DPPH and hydroxyl radical scavenging activities, in addition to ferric reducing as...
