Effect of camptothecin a potent anti cancer drug from Mappia foetida on breast cancer cell line MDA-MB-231
The anti cancer activity of different parts of Mappia foetida (leaf, bark and root) on breast cell line (MDA-MB-231) was investigated. It was found that the extracts kill the cancer cell MDA-MB-231 in dose and duration dependent manner. The IC50 of the leaf, bark and root extract against MDA-MB-231 cells are 450 and 500 µg/ml respectively. Morphological changes and abnormal nuclear morphology was...

Simultaneous determination of trans-caryophyllene and piperine for detection of exhausted drugs in an ayurvedic formulation
Admixture of exhausted drugs is one of the major menace faced by the herbal industry. This paper presents a new, simple, selective and precise high performance thin-layer chromatographic (HPTLC) method, which is validated to determine the quantities of trans-caryophyllene and piperine content in an Ayurvedic formulation Trikatu churna. The method employed HPTLC aluminum plates precoated with silica-gel 60F-254 as...

Comparative evaluation of antioxidant activity of crude extracts of Commiphora spp and formulated polyherbal tablets
This study is planned to determine the antioxidant activity. Indian medicinal plants were selected to evaluate for free radical scavenging capacities and antioxidant activities using commonly accepted assays. They were extracted with ethanol to show the best antioxidant results. Flavonoids and phenolic were included and used as standards in this study. Each sample under assay condition showed a dose-dependent free...

In vitro plant regeneration from seedling explants of Hedychium coronarium J. Koenig
Although poor seed viability and low seed germination has been reported in Hedychium coronarium but a successful procedure was established in seed germination trials in the present study and about 80% germination has been recorded in Murashige and Skoog (MS) basal medium. Six to eight day old in vitro grown seedlings, cultured on MS medium supplemented with cytokinin Benzylaminopurine (BAP) or...

Influence of harvesting date on some physicochemical properties of nectarine leaf and fruit
The influence of harvesting date were studied on antioxidant activity and some physicochemical properties of nectarine (cultivar, red gold) leaf and fruit including weight, pigments, carbohydrate and total phenolic and flavonoids contents. Leaves and fruit were harvested in four different stages; two weeks after fruit set (AFS), five weeks AFS or pit hardening (PH), three and six weeks after PH. The results showed that...

Population of herbivores insects on different sides of Caryocar brasiliense (Caryocaraceae) trees in the Brazilian Cerrado region
The goal of this work was to study the distribution of lepidopteran, coleopteran, and hymenopteran herbivores and their natural enemies within the canopy of Caryocar brasiliense (Caryocaraceae) trees in the Brazilian cerrado. We observed thirteen rare, two common, and one constant species of herbivores insects; and three rare, eight common, and one constant species of natural enemies on C. brasiliense....

In vitro antitumor and antioxidant activities of Belamcanda chinensis (L.) DC
The in vitro antitumor activities of petroleum ether, ethyl acetate and methanol extracts ofBelamcanda chinensis (L.) DC root were studied against the PC3, Bcap-37, and BGC-823 cell lines. The 1,1-diphenyl-2-picrylhydrazyl free radical (DPPH) free radical scavenging effects of these crude extracts were also tested. The results revealed that ethyl acetate extract and its isolated fractions...

Anti-inflammatory activity of Hyptis albida
Anti-inflammatory activity of chloroform and methanol extracts from aerial parts of Hyptis albida was tested on different pharmacological models in rats and mice. The plant was collected in Guadalcazar San Luis Potosí State, dried and powdered. The extracts were obtained by heating the solvent to its boiling point. The extracts free of solvent were tested in two pharmacological models,...

Evaluation of anti-inflammatory potential of Atropa acuminata in carrageenan induced inflammation in rats
The present study was envisaged to assess the rationality for the use of traditionally in vogue herb Atropa acuminata as an anti-inflammatory agent. The drug, that is, A. acuminata when tested against carrageenan induced paw oedema showed significant anti-inflammatory activity at the dose of 1 g/kg body weight. The effects were analyzed by following the evaluation of various biochemical parameters...

Antibacterial and antioxidant activity of the extracts of Waltheria indica Linn. collected from Capricorn District, Limpopo Province, South Africa
Waltheria indica L., a member of Sterculiaceae family, is widely used traditionally to treat a variety of infections in humans. Roots of W. indica were collected from William Show farm, Blouberg Area-Limpopo Province, South Africa. Water, ethanol, methanol and acetone extracts were tested for antibacterial activity. Zones of inhibition ranged from 8.9 ± 0.79 to 20.2 ± 0.57 and were dose...
