Antioxidant and antifungal activities of essential oil of Alpinia calcarata Roscoe rhizomes
Antioxidant and antifungal activity were determined for the essential oil of Alpinia calcarata Roscoe (Zingiberaceae) rhizomes. Its antioxidant properties were investigated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay and thiobarbituric acid reactive substances (TBARS) assay. Butylated hydroxy toluene (BHT) and vitamin E served as positive controls. Antifungal activ...
متن کاملAmylase production by endophytic fungi Cylindrocephalumsp. isolated from medicinal plant Alpinia calcarata (Haw.) Roscoe
Amylases are among the most important enzymes used in modern biotechnology particularly in the process involving starch hydrolysis. Fungal amylase has large applications in food and pharmaceutical industries. Considering these facts, endophytic fungi isolated from the plant Alpinia calcarata (Haw.) Roscoe were screened for amylolytic activity on glucose yeast extract peptone agar (GYP) medium. ...
متن کاملPhytochemical and cytotoxic investigations of Alpinia mutica rhizomes.
The methanol and fractionated extracts (hexane, ethyl acetate and water) of Alpinia mutica (Zingiberaceae) rhizomes were investigated for their cytotoxic effect against six human carcinoma cell lines, namely KB, MCF7, A549, Caski, HCT116, HT29 and non-human fibroblast cell line (MRC 5) using an in vitro cytotoxicity assay. The ethyl acetate extract possessed high inhibitory effect against KB, M...
متن کاملComparative Anatomical and Histochemical Characterization of the Source Plants of the Ayurvedic Drug Rasna

متن کاملAntioxidant properties of crude and fractionated extracts of Alpinia mutica rhizomes and their total phenolic content
In the present study, the antioxidant potential of the crude methanol and its fractionated extracts (hexane, ethyl acetate and water) of the rhizomes of Alpinia mutica was investigated, employing four different assays. The antioxidant assays used were 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, β-carotene bleaching, superoxide dismutase (SOD) and the reducing power assays while th...
