− A method for simultaneously identifying antioxidative compounds was developed using time-based LC-MS coupled with DPPH assay regardless of the time consuming process. The methanolic extract of Polygonum aviculare (Polygonaceae) showed significant DPPH radical scavenging activity. Time-based DPPH assay for simultaneous identification of active compounds from the extracts of P. aviculare was us...

This research aims to investigate the hypoglycemic activity of methanolic extract of Tectona grandis root in alloxan induced diabetic albino rats. A comparison was made between the action of Tectona grandis methanolic extract and a known antidiabetic drug glibenclamide (0.5mg/kg p.o).The methanolic extract of Tectona grandis linn. root was administered orally at different doses to normal rats. ...

The present study has been carried out to investigate the antibacterial activity of molluscan gastropod species Lambis lambis and to find out the possible bioactive compounds present in the body tissue extract of the experimental animal. The antibacterial activity of extracts of body tissue of L.lambis against 8 bacterial pathogens viz., Bacillus subtilis, Escherichia coli, Salmonella typhi, Kl...

Lemna paucicostata Hegelm is traditionally used as healthy feed for fish, broilers and as a source for vitamin A. In the present study, we report the isolation of an aromatic compound and a steroid glycoside from Lemna pauciscostata . The methanolic extract of dried and powdered Lemna paucicostata was fractionated using solid phase extraction (SPE). The compound was collected in a series of fra...

Aims: Hyptis suaveolens (L.) Poit, is one of the natural herbs with several medicinal properties. However, many aspects this herb still need to be explored. Therefore, our aim was examine antioxidant, antimicrobial properties and genoprotective effect H. methanolic extracts (HSME) seed, stem, root.
 Study design: extraction therapeutic suaveolens.
 Place Duration Study: 1) Department ...

In a preliminary screen, Aaptos aaptos showed significant cytotoxic activity towards a panel of cell lines and was thus subjected to bioassay-guided isolation of the bioactive constituents. In addition to the known aaptamine, two new derivatives of the alkaloid were isolated from the bioactive chloroform fraction of the crude methanolic extract. Detailed analysis by NMR and mass spectroscopy en...

The antioxidant activity of Syzygium cumini leaf extracts was investigated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging and ferric-reducing antioxidant power (FRAP) assays. The methanolic extract and its four water, ethyl acetate, chloroform, and n-hexane fractions were prepared and subjected to antioxidant evaluation. The results showed that the ethyl acetate fraction...

We observed that a methanolic whole body extract of uninfected last instar larvae of the housefly, Musca domestica, displayed antifungal and antibacterial activity. We have further purified this extract to a single active fraction using reversed phase high performance liquid chromatography. The pure fraction inhibited growth of the Gram-positive bacteria Bacillus thuringiensis and the yeast Sac...

The HT-29 colon cancer cell line was used in the current work to investigate anti-cancer efficacy of Gymnema sylvestre extracts. viability, apoptosis, flow cytometry, and mode action active fraction were also evaluated. fractions G. caused cycle arrest at S phase G2/M phase, programmed death. alcoholic showed effect cells. By applying methanolic cells, IC50 observed 140.39 μg/mL, whereas for ch...
