Homonoia riparia Lour (Euphorbiaceae) is a of the oral cavity, is the sixth most common type of cancer known source of herbal medicine in China, and riparsaponin globally (1-3). It has been reported that developing countries (RSP) is an active constituent isolated from H. riparia. The have the highest incidence rates of OSCC and it is expected aim of the present study was to investigate the antitumor that the incidence will continue to increase (4); furthermore, effect of RSP on human oral carcinoma cells and its potential OSCC commonly occurs in middle-aged and elderly males underlying molecular mechanism. RSP was isolated from roots because of tobacco and alcohol use (5). OSCC commonly of H. riparia and identified using nuclear magnetic resonance. occurs in the tissues of the oral cavity, including the gingiva, An MTT assay was used to evaluate the cytotoxicity of RSP tongue, lip, hard palate, buccal mucosa and mouth floor (4,6). on human oral carcinoma cells. Subsequently, DAPI staining OSCC exhibits a marked propensity for invasive growth and was performed to investigate the apoptotic effect of RSP.

It Cancer has been postulated that the immune response to progressive tumors is insufficient due to a deficiency in afferent Phyllanthus amarus/niruri mechanisms responsible for the development of tumor-reactive T cells. Many patients treated for cancer will Phyllanthin have their cancer recurrence, often after a long remission period. This suggests that there are a small number of Hypophyllanthin tumor cells that remain alive after standard treatment(s) – alone or in combination and have been less effective Chemotherapeutic in combating metastasis that represents the most elaborate hurdle to overcome in the cure of the disease. Immunomodulation Therefore, any new effective and safe therapeutic agents will be highly demanded. To circumvent many plant extracts have attributed for their chemoprotective potentials and their influence on the human immune system. It is now well recognized that immunomodulation of immune response could provide an alternative or addition to conventional chemotherapy for a variety of disease conditions. However, many hurdles still exist. In recent years, there has been a tremendous interest either in harnessing the immune system or towards plant-derived immunomodulators as anticancer agents for their efficacy, safety and their targeted drug action and drug de- livery mechanisms. -

Accepted 9 May, 2012 The present study was aimed to investigate the total phenols, flavonoids, carotenoids, antioxidant activity and antimicrobial activity of the bark extract of Mallotus tetracoccus (Roxb.) Kurz. Total phenols, flavonoids and carotenoids in the extract were found to be 55.35 ± 0.13 mg GAE, 260.3053 ± 1.413 mg QE and 0.182 ± 0.005 mg/g, respectively. The reducing power and metal chelating activity of the bark extract was said to be increasing with increasing concentration. The metal chelating activity (IC 50 ) of the M. tetracoccus bark extract was found to be 647.4 ± 0.321 µg/ml, which was higher compared to the standard, ethylenediaminetetraacetic acid (EDTA; 1.89 ± 0.03 µg/ml). Antioxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric thiocyanate (FTC) and thiobarbituric acid (TBA) methods. The antioxidant activity (IC 50 ) of the bark extract was said to be 0.504 ± 0.002 µg/ml by (DPPH) method. The total antioxidant activity of M. tetracoccus ethanolic bark extract was found to be 275.21 ± 0.21 mg equivalent of ascorbic acid/100 g of plant extract as determined by phosphomolybdenum method. -

Bioassay-guided isolation of this fraction resulted in identification of 15 phenolic compounds (1 – 15). These compounds were evaluated in vitro for inhibitory activity against the formation of AGE. The majority of tested compounds, excluding ethyl gallate (15), markedly inhibited AGE formation, with IC50 values of 2.2 – 89.9 µM, compared with that of the positive control, aminoguanidine (IC50 = 962.3 µM). In addition, the effects of active isolates on the dilation of hyaloid-retinal vessels induced by high glucose (HG) in larval zebrafish was investigated; (−)-epigallocatechin-3-O-gallate (6), corilagin (7), and desmanthine-2 (11) significantly decreased HG-induced dilation of hyaloid–retinal vessels compared with the HG-treated control group. -

Eighty percent methanol extracts obtained from seven Phyllanthus sp. were evaluated for antibacterial activity using the broth micro-dilution assay, anti-HIV-1 reverse transcriptase (RT) activity using the HIV-RT assay, antiradical scavenging effects and phenolic contents using the DPPH assay and Folin–Ciocalteau colorimetric method, respectively. Best antibacterial activity as indicated by the minimum inhibitory concentration (MIC) values was obtained by Phyllanthus amarus against Staphylococcus aureus (Gram-positive) with a MIC value of 17.7 μg/ml. Phyllanthus myrtifolius and Phyllanthus urinaria inhibited growth of Pseudomonas stutzeri (Gram-negative) with MIC values of 78 μg/ml and 117 μg/ml, respectively. A strong inhibition of HIV-RT was obtained by Phyllanthus pulcher (IC50 5.9 μg/ml) followed by P. urinaria and P. myrtifolius (IC50 of 10.4 and 12.7 μg/ml, respectively).

The same plants are also studied on the similar line having common names in other Indian languages viz. Marathi and Hindi, and as also in English. The bases of common plant names are then comparatively discussed. Thus as many as 50 plant species are critically studied revealing their commonalities and differences in bases of common names in different languages.

Flying squirrels consumed 4 major plant parts belonging to 9 plant species. Ficus racemosa was the most-eaten species (68.1%) during the period of the study, followed by Cullenia exarillata (9.57%) and Artocarpus heterophyllus (6.38%). The most commonly consumed food item was the fruit of F. racemosa (48.93%). Leaves formed an important component of the diet (32.97%) and the leaves of F. racemosa were consumed more than those of any other species. Flying squirrels proved to be tolerant of disturbance and exploited food resources at the fragment edge, including exotic planted species.
