Aqueous and alcoholic extracts of curcuma amda roxb. rhizomes have been evaluated for its anti tumour activity in Swiss albino mice. Alcoholic extract exhibited more potent anti tumour activity than aqueous extract. In-vitro cytotoxicity studies were confirmed by brine shrimp bioassay method. A significant increase in the life span and a decrease in the cancer cell number and tumour weight were...

Three Curcuma species, Curcuma aeruginosa (pink and blue ginger), Cu. aromatica (aromatic turmeric), and Cu. xanthorrhiza (giant curcuma), were selected for investigation of mosquito repellent activity. In a laboratory study, a 95% ethanol extract of each plant was tested for repellent activity of Aedes togoi on human volunteers. Only Cu. aromatica extract showed repellency against Ae. togoi wi...

BACKGROUND AND AIMS Genome size and chromosome numbers are important cytological characters that significantly influence various organismal traits. However, geographical representation of these data is seriously unbalanced, with tropical and subtropical regions being largely neglected. In the present study, an investigation was made of chromosomal and genome size variation in the majority of Cu...

Eleven species of Geothelphusa have been reported from southwestern Taiwan (Tainan, Kaohsiung and the northern part of Pingtung counties): G. albogilva Shy, Ng, and Yu, 1994; G. ancylophallus Shy, Ng, and Yu, 1994; G. caesia Shy, Ng, and Yu, 1994; G. lili Chen, Cheng, and Shy, 2005; G. nanhsi Shy, Ng, and Yu, 1994; G. neipu Chen, Cheng, and Shy, 1998; G. olea Shy, Ng, and Yu, 1994; G. pingtung ...

We previously found that Curcuma plants and drugs derived from Curcuma longa, C. phaeocaulis, C. zedoaria, and C. aromatica could be identified by the nucleotide differences at two sites and the existence of a 4-base indel on trnK gene. In this paper, based on species-specific nucleotide sequences, the application of a new method, single-nucleotide polymorphism (SNP) analysis was investigated t...

Curcuma phaeocaulis Valeton is a commonly prescribed Chinese medical herb for tumor therapy. In this study, an extract of Curcuma phaeocaulis Valeton referred as Cpv was prepared and its anti-tumor effect was evaluated with MCF-7 and MDA-MB-231 cells. Curcuma phaeocaulis Valeton power was extracted with ethanol and the main components of the extract (Cpv) were analyzed with HPLC. The effect of ...

Oral feeding of 50% EtOH extract of Curcuma longa to male rats at the dose of 1gm/kg body weight caused significant reduction of serum cholesterol, triglycerides and phospholipids (P≤0.01 to 0.001). Whereas the SGOT levels aware not reduced significantly. Fertility test showed 80% negative result. The negative fertility results reflects the arrest of spermatogenesis and depletion of androgen le...
