Curcumin, the active molecule present in Curcuma longa is known for its antitumour, antioxidant, antiarthritic, anti-amyloid, anti-ischemic, anti-inflammatory activities. In addition, it may also be effective in treating malaria, prevention of cervical cancer, etc. High-performance thin-layer chromatography (HPTLC) method has been employed for determination of curcumin in four varieties of turm...

The objective of the study was to determine the effect of role of combination of extracts of Curcuma zedoaria and Aloe vera in reducing melanin synthesis. Yarying concentrations of the extracts of the plan ts were tested for melanogenesis and tyrosinase activity in murine melanoma cells. Extract combinations at a concentrati on of 1-5μ1 showed 50J 50% reduction in melanogenesis without altering...

Curcuma longa L. or turmeric of the family Zingiberaceae is widely used in Thai traditional medicines for the treatment of rash, itching, tinea, and ringworm. Previous studies on turmeric oil reported effective antifungal activity against dermatophytes, a group of fungi that causes skin diseases. In this study, turmeric creams containing 6 and 10% w/w turmeric oil were prepared and tested again...

The present investigation was carried out at field trail of Main Experimental Station, Vegetable Science N.D.U.A. & T., Kumarganj, Faizabad (U.P.) during 2011-12 to study the performance of turmeric cultivars. Cultivar NDH-7 and NDH-8 was found superior in growth characteristics such as plant height, yield of rhizome/plant. NDH-8 found tallest (111.2 cm) while, yield of rhizome per plant was re...

A preparative gas chromatography (pGC) method was developed for the separation of volatile components from the methanol extract of Curcuma rhizome. The compounds were separated on a stainless steel column packed with 10% OV-101 (3 m × 6 mm, i.d.), and then, the effluent was split into two gas flows. One percent of the effluent passed to the flame ionization detector (FID) for detection and the ...

Germacrone is a major activity component found in Curcuma zedoaria oil product, which is extracted from Curcuma zedoaria. In the present study, novel germacrone derivatives were first designed based on the theories of bioalkylating agents, synthesized, and then investigated for their inhibition effects on Bel7402, HepG2, A549, and HeLa cells. Moreover, the study also evaluated the inhibition of...
