Leelawat S, Leelawat K
To date, there are no effective chemotherapeutic treatments for cholangiocarcinoma. The anticancer effects of Moringa oleifera extracts have been demonstrated in various kinds of cancers. Therefore, we evaluated the anticancer effects of M. oleifera extracts on cholangiocarcinoma cells. In this study, RMCCA1 and KKU100 human hilar cholangiocarcinoma cell lines were treated with Moringa extracts and examined for cell viability and apoptosis. Factors that contribute to cancer-cell survival in response to stress were assayed, including mitochondrial membrane potential changes and reactive oxygen species (ROS) production. The results showed that Moringa extracts inhibited cell proliferation and induced cell apoptosis. In addition, treatment with Moringa leaf and seed extracts (MLE and MSE) induced a marked decrease in mitochondrial membrane potential and an increase in reactive oxygen species (ROS) production in cholangiocarcinoma cells. Consequently, pretreatment with N-acetylcysteine (NAC), an antioxidative agent, completely inhibited the cytotoxicity of MLE and MSE in both cholangiocarcinoma cell lines. In conclusions, these results indicate that the Moringa extracts induce cytotoxicity in cholangiocarcinoma cells through the induction of ROS accumulation and mitochondria dysfunction. These findings suggest that after future studies, M. oleifera may serve as a potential therapeutic agent for cholangiocarcinoma.

17. A Review: Dye Yielding Sources and their Importance
Yadav Rajesh, Yadav Nita, Kharya Murli Dhar
In India, there are more than 450 plants that can yield dyes. In addition to their dye-yielding characteristics, some of these plants also possess medicinal value. Though there is a large plant resource base, little has been exploited so far. Due to lack of availability of precise technical knowledge on the extracting and dyeing technique, it has not commercially succeeded like the synthetic dyes. This review examines some of the existing methods for colouring the hair and skin using natural material (such as henna) and proposes a parallel technology that exists in the dyeing of wool and fabrics to extend the colour range. One of the major problems is the functional part of the herb (i.e. the colouring dyestuff). The chemistry is not always known by the formulator and therefore the concept of a natural dye is rejected. In reality, many of the dyestuffs in natural materials are identified and can be quantified or standardized in the specification for the raw material. The dyeing of hair has been practiced since the time of earliest Man. When it was impractical to dye the hair, then the wearing of wigs was customary, even as early as the period of the ancient Egyptians. The use of natural dyes on the hair has not made very great progress, and this is due to a number of factors that should not be the reason for despair.

Dr. Sarada. J, Uma Kranthi. S
Development of multidrug resistant pathogenic bacterial strains has become more prevalent. Novel therapeutic approaches to treat drug resistant bacterial infections are gaining momentum. Disruption of quorum sensing (Quorum Quenching) attenuates the pathogenicity without imposing resistance in bacteria. Preliminary evaluation of QSI activity of certain medicinal plants of Indian origin were tested against an established pathogen of Pseudomonas sps. Out of the plant extracts tested Calotropis leaf extract had the potential QSI activity. Calotropis leaf extract could not affect the growth proving that it does not have any antibactericidal activity but at the same time it could reduce two out of three virulence characters like pyocyanin and protease activity. QSI activity was confirmed by a bio-inidicator organism C. Violecium 12472 as violacein inhibition assay. Concentration of AHL molecule were tested in treated cultures of Pseudomonas using CV026 as violacein induction assay. Qualitative tests for phytochemicals of the extract had revealed that it has phenolic compounds, terpenoids, alkaloids and saponins. TLC and HPLC analysis along with fractional separation of phytochemicals proved that it has mixture of saponins, alkaloids, terpenoids and phenolics. Calotropis leaf extract can be further exploited as potential QSI agent as these phytochemicals could decrease the drug resistance of certain clinical bacterial isolates like Enterococcus faecalis and Proteus vulgaris.
29. Hepatoprotective Effect of Zingerone [4-(4-Hydroxy-3-Methoxyphenyl) Butan-2-One] in Lipopolysaccharide Induced Liver Injury Mouse Model through Downregulation of Inflammatory Mediators
Lokender Kumar, Sanjay Chhibber, Kusum Harjai
Lipopolysaccharide (LPS) is responsible for causing inflammation leading to septic shock or organ failure. During treatment of infection, high amount of LPS is released in blood circulation due to immediate lysis of bacteria. Since liver helps in clearing LPS from the body, hence it remains the primary target to be stimulated by LPS releasing vigorous amount of inflammatory molecules leading to liver injury. Available anti-inflammatory chemotherapy fails in such situation because it relies predominantly on specific or non specific inhibitors of cyclooxygenase enzyme activity (COX-2) with broad range of hepatic, renal and cardiovascular side effects. There is a need to replace the potential therapies targeting suppression of LPS induced inflammation with those having no or minimal side effects. Active components from dietary medicinal plants like ginger (Zingiber officinale) are potential source of non toxic antioxidant as well as anti-inflammatory molecules. In the present study, protective effect of zingerone was evaluated against inflammation induced by LPS in terms of liver histology, serum endotoxin levels, liver function markers (AST, ALT, ALP) and inflammatory mediators (malondialdehyde, reactive nitrogen intermediates, myeloperoxidase). Relative mRNA expression of LPS induced inflammatory markers TLR4, TNF-α and iNOS was also evaluated in zingerone treated and untreated groups. Hepatoprotective effect of zingerone was observed leading to significant improvement in liver histology, decreased levels of serum endotoxin levels, liver function markers and MPO, MDA, RNI. It also showed significant down regulation of mRNA expression of TLR4, TNF-α and iNOS suggesting potent anti-inflammatory activity of zingerone against P.aeruginosa LPS induced liver injury.

32. Marker Based Standardization of Extracts and Formulations of Achyranthes aspera
Tatke P. A., Desai S. S., Gabhe S. Y.
There is great demand of herbal medicines in the developed as well as developing countries as they are considered to be effective and safe. Although they are as efficacious as allopathic medicines and safer as compared to allopathic medicines, they are not globally accepted. The major reason behind this fact is that they lack proper standardization technique. The present paper discusses a new, simple, accurate and reproducible analytical method using betaine as marker. This developed and validated method was applied for marker based standardization of extracts and marketed formulations containing Achyranthes aspera. The method employs C18 column as stationary phase and acetonitrile: water (10:90, v/v) as mobile phase. Flow rate of the mobile phase was kept at 1.0 ml/min and detection was carried out at 205 nm. The developed method was validated as per ICH guidelines. Linearity was obtained over the range of 15-70 µg/ml. LOD and LOQ were found to be 5 µg/ml and 15 µg/ml, respectively. The recovery of betaine was between 107.28 % -108.35 %. The method is reproducible and robust. The developed and validated method can be used as quality control tool for the analysis of extract and herbal formulations containing Achyranthes aspera using betaine as marker.

Kanakarajan Vijayakumari Pratheesh, Vijayakumar Jacintha Shine, Jacob Emima, Gopi Lilly Renju, Ramachandran Rajesh
The failure of existing therapeutic interventions and chemotherapy draws the necessity of new and efficient drugs in the treatment of cancer. Plant based drugs always hold pre-eminence owing to the factors like lesser side effects and decreased chances of development of drug resistance. Tylophora indica a plant belonging to Asclepiadaceae is widely used in traditional medicine for the treatment of different aliments as antibacterial, anti-inflammatory and antiviral agents. The lack of scientific evidences regarding the anticancer potential of this plant limits its validation as chemotherapeutic agents. In the current study the anti-proliferative effect of alcoholic extracts of Tylophora indica on HCT-15 colon cancer cell lines was studied in detail. Phytochemical analysis confirms the presence of alkaloids and flavaniods as the major secondary metabolites present in ethanolic extracts. Invitro free radical scavenging assays confirms significant antioxidant activity. Dose dependent invitro studies confirm an IC50 value of 40 mcg/ml with MTT and neutral red uptake assays. Increased LDH leakages shows increased membrane damage in cells treated with ethanol fractions of Tylophora indica. Apoptosis was determined by EtBr/Acridine orange staining methods which confirmed presence of apoptotic/ necrotic cells upon treatment with extracts. The results suggests therapeutic potential of Ethanolic extracts of Tylophora indica against colon cancer.

Suhashini.R, Sindhu.S, Sagadevan.E
Diabetes is a metabolic disorder that occurs due to poor secretion of insulin by pancreas. Insulin helps to metabolize blood sugar. Hence this results in high glucose level in blood. Presently, diabetes is considered as a big killer and is among the most significant diseases in the developed world. The incidence of diabetes is increasing every day and this indicates the increasing need for the treatment of diabetes. The blood glucose level can be regulated by various mechanisms. In vitro antidiabetic assays such as glucose uptake by yeast cells, glucose diffusion assay, alpha amylase inhibition assay and glycosylation of hemoglobin assay are performed. Using these assays, the antidiabetic activity of the plant Psoralea corylifolia is determined. Qualitative and quantitative phytochemical analysis reveals all the bioactive compounds present in the crude extract of the plant. Our results show that methanolic extract has an effective activity when compared to ethyl acetate and hexane extracts. Hence methanolic extract of Psoralea corylifolia possess higher antidiabetic activity. The compounds which contribute to its antidiabetic activity were identified, characterized and separated by thin layer chromatography. MTT assay for L6 cell lines was performed and was found that the plant extract showed a minimum toxicity.
