Phytochemical screening and antioxidant potential of Parthenocissus quinquefolia [L.] planch extracts of bark and stem

The phytochemical screening and antioxidant potential of bark and stem of Parthenocissus quinquefolia [L.]planch was assessed in order to verify its ethnopharmacological significance. All major secondary metabolites e.g. alkaloids, flavonoids, saponins, terpenoids, tannins, reducing sugars, cardiac glycosides and anthraquinones were present. Antioxidant activity was analysed by using five techniques which included DPPH Free Radical Scavenging Activity, FRAP [Ferric Reducing Antioxidant Power], TAA [Total Antioxidant Activity, TPC [Total Phenolic Content and MC [Metal Chelating] Activity. Ethanolic extract of bark showed the highest scavenging effects of 90.01+/-0.01%, with IC50 value of 24.32mg/ml. Aqueous stem extract showed best activity with IC50 value of 13.6+/-0.34mg/ml. The significance antioxidant potential indicates the effectiveness of bark and stem of P. quinquefolia in treatment of many diseases

Phytochemical screening, GC-MS analysis and in vitro antioxidant activity of pollen of Centella asiatica [Linn] urban a traditional medicinal plant

In the present study the crude extracts of pollen of Centella asiatica [Linn.] Urban were explored for their antioxidant potential using Ferric Reducing Power, Metal Chelating Activity and Trolox Equivalent Antioxidant Capacity assays. In crude extracts of pollen antioxidant components were initially extracted in methanol and further fractionated in solvents of different polarity, such as n-Hexane, Chloroform, Ethyl Acetate and Water exhibited reasonable antioxidant activity. The extract was found to contain large amounts of phenolic and flavonoid contents ranged from 143-1155 mg/1 of gallic acid equivalent [GAE] and 911-2488 mg/1 of quercetin [QE] respectively. Moreover, Super oxide Anion Radical Scavenging Activity and GS-MS analysis were also carried out

In vitro antioxidant potential and free radical scavenging activity of various extracts of pollen of Typha domigensis Pers

Antioxidant potential of the pollen of Typha domigensis Pers. using Ferric Reducing ower, Metal Chelating Activity and Trolox Equivalent Antioxidant Capacity [TEAC] assays has been carried out in the current research work. The antioxidant components were initially extracted from the pollen in methanol and were further fractionated in solvents of different polarity such as n-Hexane, Chloroform, Ethyl Acetate and Water. Methanol extract which was found to have high reducing power, total phenolic contents with high metal chelating activity, has considerable prospective to utilize as a natural antioxidant and be capable to link with the total phenolic contents of plant

Comparative Pharmacognostic evaluation of some species of the genera Suaeda and Salsola leaf [Chenopodiaceae]

The genera Suaeda and Salsola are halophytic plants belong to the family Chenopodiaceae. Species of these genera have been extensively used in traditional medicines against many diseases due to their various bioactive compounds such as carotenoids, vitamins, sterol, phenolic compounds etc

The present research was carried out to establish detailed pharmacognosy of Suaeda fruticosa, Suaeda monoica, Salsola imbricata and Salsola tragus, which included macroscopy, microscopy, physico-chemical parameters and qualitative phytochemical screening of leaf samples extracted with methanol and chloroform

It was observed that macroscopic and microscopic characteristics were diagnostic features and can be used for distinction and identification of these closely related plant species

Phytochemically, these plant species are rich in constituents like anthraquinones, alkaloids, carbohydrates, cardiac glycosides, flavonoids, saponins, phenolic compounds and terpenoids. Physico-chemical parameters revealed that in all investigated plant species; methanol extractive values were higher than that of chloroform

Moreover, total ash values were found to be higher than other acid insoluble and water-soluble ash values, while a considerable amount of moisture was present in the species of both genera. On the basis of pharmacognosy, species of Suaeda were found to be more promising than Salsola

Present investigation will contribute towards establishment of pharmacognostic profile of these medicinally effective plants species
