In vitro aqueous and ethanol extracts of Withania somnifera (leaves and fruits) and Curcuma Longa were evaluated for antibacterial activities against Basillus subtillis, Staphylococcus aureus, Escherichia coli and S.epidermitis. The inorganic extract of W. somnifera leaves showed more antibacterial activity as compared to the organic fraction. While both the organic and inorganic phases of frui...

Curcuma oligantha Trimen var. oligantha (Zingiberaceae) is an erect perennial herb with white flowers spotted yellow at the throat of the labellum. It is distributed in Sri Lanka and Karnataka (1, 2). The Curcuma rhizomes are large, tuberous, orangered and aromatic and substituted for turmeric. The rhizomes are prescribed to treat bruises, sprains, skin eruptions, infections and to improve comp...

Curcumin is a natural bioactive compound originated from the rhizomes of turmeric (Curcuma longa L.). This study was performed to investigate formic acid and microwave assisted extraction of curcumin from turmeric (Curcuma longa L.). In order to enhance the curcumin extraction, different parameters such as particle size, effect of pretreatment with water, radiation intensity and type of solvent...

Two new species of Curcuma, C. sattayasaii A. Chaveerach & R. Sudmoon and C. zedoaroides A. Chaveerach & T. Tanee with rhizomes traditionally used for many decades as cobra-bite antidotes are described and illustrated. Curcuma sattayasaii is similar to C. longa L., but differs in rhizome horizontally branching on ground; coma bracts pinkish-white or pinkish-pale green; corolla pale yellow with ...

Bacterial cellulose- Curcuma Longa Linn from acetobacter xylinum has been produced. The aim of research: To isolate Cellulose-Curcuma Acetobacter and to improve activity catalitic bacterial cellulose. Morphology properties was carried out on sample cellulose extract. This characteristic test by Scanning Electron Microscope (SEM).

High-speed counter-current chromatography (HSCCC) was applied to isolate and purify bioactive compounds in the essential oil of the rhizomes of Curcuma wenyujin. Two sesquiterpenes germacrone and curdione were successfully isolated and purified using two-phase solvent system composed of petroleum ether-ethanol-diethyl ether-water (5/4/0.5/1, v/v) in tail to head elution mode. 62 mg of germacron...

Plant density was varied with P, Ca, Mg, and KNO3 in a multifactor experiment to improve Curcuma longa L. micropropagation, biomass and microrhizome development in fed-batch liquid culture. The experiment had two paired D-optimal designs, testing sucrose fed-batch and nutrient sucrose fed-batch techniques. When sucrose became depleted, volume was restored to 5% m/v sucrose in 200 ml of modified...

Crude ethanolic extract and column chromatographic fractions of the Allepey cultivar of Curcuma longa Roxb, commonly called turmeric (tumeric) in commerce, were used as a stain for tissue sections. Staining was carried out under basic, acidic and neutral media conditions. Inorganic and organic dissolution solvents were used. The stain was used as a counterstain after alum and iron haematoxylins...

The Zingiberaceae, the largest family in the Zingiberales, comprises nearly 50 genera and 1,000 species and is pantropical, concentrated mainly in the old world, chiefly in Indomalaysia. Members of the family yield spices, dyes, perfumes, medicines and a number of ornamental species are cultivated for their showy flowers. Recently this plant has acquired great importance in the present-day worl...

Curcuma longa is well known for its use as spice and medicine. The remarkable feature of the plant is the presence of rhizome, which provides an interesting habitat for association by various groups of bacteria. Some of these associated endophytic bacteria can have growth-promoting effects. In the current study, two species of endophytic Paenibacillus has been identified from the rhizome as ind...
