Background: In recent years, plants natural products have gained considerable attention as natural preservers for use in different industries. Due to their free radical scavenging activities, phenolic compounds can prevent a wide range of diseases such as cancers and cardiovascular and neurodegenerative diseases. For a long time, different Ferulago species have been in use as medicina...

The present study was carried out to determine the concentration of some bioactive phytochemicals (ascorbic acid, carotenoids, total phenolics, protein and carbohydrate) and their antioxidant activity in the some medicinal plants. To screen out the plants, as well as their parts having higher antioxidant activities, all main parts of plants were screened. Out of thirteen plant samples, ethanoli...

Bromelia balansae (Family Bromeliaceae) is a medicinal plant commonly used in the central region of Brazil as a cough syrup and also eaten roasted. The methanolic extract of ripe fruits was analyzed by chromatographic methods and spectrometrically. Four glycoside flavonols were isolated: kaempferol-3-O-α-L-rhamnopyranoside (1), kaempferol-3-O-α-L-rhamnopyranosyl-(1-->6)-ß-D-glucopyranoside (2),...

Introduction: The phytochemicals in medicinal plants are defined as bioactive non nutrient plant compounds in fruits, vegetables and grains that have been linked to reducing the risk of major chronic diseases. The medicinal plant are promising to have such have effective medicinal property due to presence of phytochemical compounds like alkaloids, tannins, flavonoids and phenolic compounds. The...

The fruiting body of Inonotus obliquus, a medicinal mushroom called chaga, has been used as a traditional medicine for cancer treatment. Although this mushroom has been known to exhibit potent antioxidant activity, the mechanisms responsible for this activity remain unknown. In our investigation for free radical scavengers from the methanolic extract of this mushroom, inonoblins A (1), B (2), a...

In present study, the comparative in vitro free radical scavenging activities of methanol extracts from three indigenous medicinal plants viz. Amla, Bitter gourd and Neem were evaluated by 1, 1-diphenyl-2-picryl-hydrazil (DPPH) radical scavenging method. Ascorbic acid was used as the reference. All of the plant extracts exhibited promising antiradical effects in a concentration dependent manner...

This study was done to investigate the interaction effect of the mixture of each pair of traditional medicinal plants including: Sage (Salvia officinalis), Hawthorn (Crataegusoxyacantha), Walnut Leaf (Juglansregia L.), Red Cabbage (Brassica oleracea), and Yellow Sweet Clover (Melilotus officinalis) on the antioxidant activities and free radical scavenging by using DPPH (2, 2-diphenyl-1-picrylhy...

The aim of the present study is to determine the antioxidant, carotene and alkaloids content of the selected plant leaves namely spinach oleracea and Annona squamosa. The antioxidant screening was done by DPPH free radical scavenging assay using shade dried leaf extracts. The results showed that IC50 for Annona squamosa and Spinach oleracea was 68.24 (μg/ml), 42.57 μg/ml respectively. Annona sq...

Rutin is a phenolic compound and found in many plant species. Its name is derived from Ruta graveolens a plant that contain this compound. Rutin has many health benefits like it inhibits platelet aggregation, inflammation, hemorrhoid development etc. It is also used in dietary supplements of human beings for its health benefits. Therefore, this study was planned to investigate its other medicin...

The powder samples and methanol extract of 11 medicinal plants were subjected to analysis of proximate composition and measurement of antioxidant activity. Different parameters studied include phenolic contents, moisture, ash, crude fiber, fats and waxes. The assays employed were ferric reducing antioxidant power, trolox equivalent antioxidant capacity and scavenging effect on the 1,1-diphenyl-...
