preliminary studies on anti inflammatory activity of zingber officinale rosc vitex negundo linn and tinospora cordifolia willid miers in albino rats
Indian Journal of Pharmacology, 1999Co-Authors: U Jana, Rabindra Nath Chattopadhyay, Badri Prasad ShawAbstract:Objectives: To study the anti-inflammatory effect of Zingiber officinale, Vitex negundo and Tinospora cordifolia on carrageenin induced hind paw oedema and cotton pellet granuloma in rats. Methods: Hind paw oedema was produced by subplanter injection of carrageenin and paw volume was measured plethysmometrically at '0' and '3' hours intervals after injection. Cotton pellet granuloma was produced by implantation of 50(1mg sterile cotton in each axilla under ether anaesthesia. The animals were treated with Zingiber officinale, Vitex negundo, Tinospora cordifolia and the standard drugs acetylsalicylic acid and phenylbutazone. Results: Zingiber officinale, Vitex negundo and Tinospora cordifolia produced significant anti-inflammatory effect in both acute and subacute models of inflammation. In acute inflammation, effect of Tinospora cordifolia was more than acetylsalicylic acid. In subacute inflammation, the results of these drugs were less than phenylbutazone. Conclusion: Zingiber officinale, Vitex negundo and Tinospora cordifolia possess anti-inflammatory effects in both acute and subacute inflammation.

Metabolic profiling and phylogenetic analysis of medicinal Zingiber species: Tools for authentication of ginger (Zingiber officinale Rosc).
Phytochemistry, 2005Co-Authors: Hongliang Jiang, Zhengzhi Xie, Hyun Jo Koo, Steven P. Mclaughlin, Barbara N. Timmermann, David R. GangAbstract:Abstract Phylogenetic analysis and metabolic profiling were used to investigate the diversity of plant material within the ginger species and between ginger and closely related species in the genus Zingiber (Zingiberaceae). In addition, anti-inflammatory data were obtained for the investigated species. Phylogenetic analysis demonstrated that all Zingiber officinale samples from different geographical origins were genetically indistinguishable. In contrast, other Zingiber species were significantly divergent, allowing all species to be clearly distinguished using this analysis. In the metabolic profiling analysis, the Z. officinale samples derived from different origins showed no qualitative differences in major volatile compounds, although they did show some significant quantitative differences in non-volatile composition, particularly regarding the content of [6]-, [8]-, and [10]-gingerols, the most active anti-inflammatory components in this species. The differences in gingerol content were verified by HPLC. The metabolic profiles of other Zingiber species were very different, both qualitatively and quantitatively, when compared to Z. officinale and to each other. Comparative DNA sequence/chemotaxonomic phylogenetic trees showed that the chemical characters of the investigated species were able to generate essentially the same phylogenetic relationships as the DNA sequences. This supports the contention that chemical characters can be used effectively to identify relationships between plant species. Anti-inflammatory in vitro assays to evaluate the ability of all extracts from the Zingiber species examined to inhibit LPS-induced PGE 2 and TNF-α production suggested that bioactivity may not be easily predicted by either phylogenetic analysis or gross metabolic profiling. Therefore, identification and quantification of the actual bioactive compounds are required to guarantee the bioactivity of a particular Zingiber sample even after performing authentication by molecular and/or chemical markers.

antioxidant activities total phenolics and flavonoids content in two varieties of malaysia young ginger Zingiber officinale roscoe
Molecules, 2010Co-Authors: Ali Ghasemzadeh, Hawa Z E Jaafar, Asmah RahmatAbstract:Ginger (Zingiber officinale Roscoe) is a well known and widely used herb, especially in Asia, which contains several interesting bioactive constituents and possesses health promoting properties. In this study, the antioxidant activities of methanol extracts from the leaves, stems and rhizomes of two Zingiber officinale varieties (Halia Bentong and Halia Bara) were assessed in an effort to compare and validate the medicinal potential of the subterranean part of the young ginger. The antioxidant activity and phenolic contents of the leaves as determined by the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay and the total amounts of phenolics and flavonoids were higher than those of the rhizomes and stems. On the other hand, the ferric reducing/antioxidant potential (FRAP) activity of the rhizomes was higher than that of the leaves. At low concentration the values of the leaves' inhibition activity in both varieties were significantly higher than or comparable to those of the young rhizomes. Halia Bara had higher antioxidant activities as well as total contents of phenolic and flavonoid in comparison with Halia Bentong. This study validated the medicinal potential of the leaves and young rhizome of Zingiber officinale (Halia Bara) and the positive relationship between total phenolics content and antioxidant activities in Zingiber officinale.

Isolation and molecular analysis of R-gene in resistant Zingiber officinale (ginger) varieties against Fusarium oxysporum f.sp. Zingiberi.
Bioresource technology, 2007Co-Authors: R. Swetha Priya, R. B. SubramanianAbstract:Abstract Marker assisted selection (MAS) of resistant varieties is a reliable and faster method of selecting the right varieties for cultivation. The aim of the present study is to find the genes responsible for resistance in highly resistant varieties. In the present work we report the presence of a Resistance (R) gene of CC–NBS–LRR class of plant resistance genes. Both direct PCR amplification from genomic DNA as well as cDNAs, yielded a 0.6 kb DNA sequence indicating the absence of an intron. Sequence analysis of the PCR amplicon obtained from the genomic DNA showed very high homology to R-genes. An interesting observation from the present study is the presence of the R-gene in only resistant varieties. Neither the partially resistant or susceptible varieties showed the presence of this gene sequence. This in turn raises interesting questions on the evolution of these ginger varieties. The cloned R-genes provide a new resource of molecular markers for rapid identification of fusarium yellows resistant ginger varieties.
