Indian medicinal plants traditionally used for the treatment of viral infections with high fever, arthritis, inflammation were investigated for their in vitro antiviral activity against the Asian and East Central South African lineage of Chikungunya virus. In vitro cytotoxic assay of aqueous, aqueous ethanolic and ethanolic extracts of Alpinia Galanga (L) Willd., Alpinia Officinarum Hance., And...

Labda-8 (17), 12-diene-15, 16-dial and coronarin E were isolated from the chloroform extract of the rhizomes of Alpinia javanica. The structures were elucidated spectroscopically. This is the first report of the isolation of coronarin E from Alpinia species. The distribution of these two labdane diterpenes within the Zingiberaceae is reported.

Present study was conducted to evaluate the effect of aqueous methanolic extract from Saccharum officinarum on the sporulation and morphology of oocysts of four Eimeria species (Eimeria tenella, E. necatrix, E. mitis, E. brunetti) of poultry. Sporulation inhibition bioassay was used to evaluate the activity of Saccharum officinarum extract (SOE) on the sporulation of coccidian oocysts. In this ...

Objective: The objective of the present study was to isolate galangin from methanolic extract of Alpinia officinarum (MEAO) by bioassay guided fractionation using hexane–ethyl acetate as a solvent and evaluated the anti-arthritic effect of galangin and MEAO in complete Freund’s adjuvant (CFA) induced arthritis in wistar rats. Methods: Arthritis was induced by intradermal injection of CFA into t...

The Saccharum sensu stricto (s.s) genus consists of three recognised species: S. spontaneum, S. officinarum and S. robustum, and three subspecies: S. sinense, S. barberi and S. edule. Currently, limited knowledge is available about the precise descent of these species from one another. Modern sugarcane arose through the ‘Nobilization’ process, and it is believed that S. officinarum and S. spont...

1'-Acetoxychavicol acetate (ACA) is a phenylpropanoid present in Alpinia galanga (L) Willd syn. Languas galanga. The objective of this study was to isolate 1'-Acetoxychavicol acetate (ACA) from acetone extract of Alpinia galanga (AEAG) and evaluate anti-arthritic activity of 1'-Acetoxychavicol acetate (ACA) and acetone extract of Alpinia galanga (AEAG) on complete Freund’s Adjuvant-induced arth...

The new compounds 2-methyl-6-isopropyl-7-hydroxymethyl naphthalene (1), oxyphyllenone H (2), epi-oxyphyllenone (6), (E)-labda-12,14-dien-15(16)-olide-17-oic acid (3), and two new natural products 4 and 5 were isolated from the ethyl acetate part of 95% ethanol extract of Alpinia oxyphylla, together with six known compounds 7-12. The inhibitory effects of compounds 1-12 on α-glucosidase were eva...
