As many as 70-90% of ulcers are associated with H.pylori a spiral shaped bacterium that lives in the acidic environment of the stomach. Ulcers can also be caused by drugs such as aspirin and other NSAIDS. Naturally occurring the Pytoconstituents like flavanoids, Saponin, tannins gums and mucilage are functioned to cure the peptic ulcer. Phytoconstitents is very cheap with economic and with out side effect produce when compare to allopathic drugs. Phytochemicals produced medicinal herbs also screened.

The two largest genera of the family are Combretum and Terminalia which contains the more no. of species. The members of the family are widely distributed in tropical and subtropical regions of the world. Most members of the trees, shrubs or lianas of the combretaceae family are widely used medicinally. The members of this family contain the different phytoconstituents of medicinal value e.g tannins, flavonoids, terpenoids and alkaloids. Most of the species of this family are used as antimicrobial, antioxidant and antifungal. The biological activities of the some members of this family yet not found. Apart from the medicinal value many members of the Combretaceae are of culinary and ornamental value. Keywords: Combretaceae, Tannins, Flavonoid, Terminalia, Combretum.

Accepted 2 August, 2013 Gastric ulcer generally results from persistent erosions and damage of the stomach wall which become perforated and develops into peritonitis and massive haemorrhage as a result of inhibition of the synthesis of mucus, bicarbonate and prostaglandins. The commercially available antiulcer drugs usually have various side effects. Due to these side effects, there is a need to find new antiulcerogenic compound(s) with potentially less or no side effects and medicinal plants have always been the main source of new drugs for the treatment of gastric ulcer. Several hundred plant genera are used medicinally mainly in the form of herbal preparation in indigenous system of medicine in different countries for the treatment of ulcers. In this review, we have given a detailed description of ulcer and its causative factors along with medicinal plants with antiulcer potency.

Later it has established two Regional Chapters one at Thrissur and another at Kozhikode. One of the objectives of IFK is to undertake studies on topics useful in Forest Management. Accordingly the Project-“A Comprehensive Study on the Socio- economic and Cultural aspects of Sacred Groves in Kerala” was prepared and submitted to Kerala Forest Department in June 2012. This project was examined and discussed by the Kerala Forest Development Fund Research Committee in its meeting held on 18th August 2012 and was approved for implementation. The project envisages a detailed study of Sacred Groves (SGs) in all the districts of Kerala one by one. To start with Thiruvananthapuram District was allotted and IFK completed the study and submitted the report in November 2013.Subsequently districts such as Kollam,Alappuzha,Thrissur and Kozhikode were allotted. The study was completed and all the reports in respect of these five districts have been submitted. This is the sixth report now being submitted.

E-mail: [email protected] Abstract The genus Austrothrips is considered a nomen dubium because the types are lost and the type species description is uninformative. Austrothrips flavitibia Moulton is transferred to the genus Teuchothrips and Austrothrips vanuaensis Moulton is transferred to the genus Solomonthrips. The gall-inducing Austrothrips cochinchinensis Karny is transferred to Ocnothrips as a senior synonym of the type species, O. indicus. The host of cochinchinensis is recognised as a vine-like shrub, Getonia floribunda, that is widespread between western India and southeast China. Key words: Ocnothrips, Teuchothrips, Solomonthrips, leaf-galls, fungus-feeding Introduction The induction of pouch galls by a thrips known as Austrothrips cochinchinensis on the axillary buds of a plant re- ferred to as Calycopteris floribunda was first reported by Rao (1924). This author discovered the galls at Malabar in southwestern India, and he thanked H. Karny for examining the thrips and identifying them as a species previ- ously known only from Thailand (Karny 1922). Multiple references to these galls and their thrips are available (Ananthakrishnan 1978, 1984a,b, 1992; Ananthakrishnan & Raman 1989), and the insect/plant association has been assumed to be an example of host specificity.

  • Cytotoxic and Genotoxic Effect of Biofabricated Zinc Nanoparticles on Mitotic Chromosomes of Drimia Polyantha

ISSN: 2249-9504 INTERNATIONAL JOURNAL OF PHARMACEUTICAL, CHEMICAL AND BIOLOGICAL SCIENCES Available online at www.ijpcbs.com Research Article CYTOTOXIC AND GENOTOXIC EFFECT OF BIOFABRICATED ZINC NANOPARTICLES ON MITOTIC CHROMOSOMES OF DRIMIA POLYANTHA (ROXB.) JESSOP Azharuddin Daphedar and Tarikere C Taranath* Environmental Biology Laboratory, P. G. Department of Studies in Botany, Karnataka University, Dharwad, Karnataka 580 003, India. ABSTRACT Green synthesis of nanoparticles and their diverse applications are grown in various fields of nanoscience. In the present investigation, genotoxic effect of biogenic zinc nanoparticles on the root tip chromosomes of Drimia polyantha was evaluated. Biogenic zinc nanoparticles were characterized by UV-visible, XRD, FT-IR, AFM and HR-TEM analysis. The UV spectrum shows characteristic absorption peak at 374 nm. FTIR data suggested involvement of different functional groups in leaf extract were responsible for the reduction, capping and stabilization of ZnNPs. XRD results confirmed the crystalline nature of zinc nanoparticles with face centered cubic structure. AFM and HR-TEM images reveal the size and shape of nanoparticles. The size of ZnNPs ranges between 5 to 80 nm and are spherical in nature. The effect of zinc nanoparticles on mitotic index (MI) and the chromosomal aberrations (CAs) was determined by the exposing root meristimetic cells of D. polyantha to different concentrations viz. 4, 8, 12 and 16 μg/ml of zinc nanoparticles suspension at the interval of 6, 12, 18 and 24 hrs. The investigation, revealed that the significant decrease (19.43±1.58) in mitotic index and increase in chromosomal aberrations (36.09±3.29), dose and duration dependent, when compared to control.

Email: [email protected] Received: 04 Feb 2014, Revised and Accepted: 14 Mar 2014 ABSTRACT Objective: The aim of the present study was to investigate the in vitro antioxidant potential of various extracts of whole plant of Calycopteris floribunda (Lam.) as well as to establish the best procedure to obtain extracts containing active principles. Methods: In this context, we conducted a bioassay of the extracts using DPPH (α, α -Diphenyl- Β -Picryl Hydrazyl) radical scavenging activity, superoxide anion scavenging activity and iron chelating activity. The results were compared with reference standard antioxidants rutin, quercetin and EDTA respectively. Results: The ethyl acetate extract of Calycopteri floribunda exerted effective DPPH radical scavenging activity. The IC50 Values of ethyl acetate of C. floribunda and Rutin were found to be 510µg/ml and 480µg/ml respectively. The lower the IC50 Value indicates the higher free radical scavenging ability. An IC50 value was found that ethyl acetate extract of C. floribunda is more effective in scavenging superoxide radical when compared to methanol and petroleum ether extracts. But when compared to all the three extracts with Quercetin (standard) the ethyl acetate extract of C. floribunda showed similar result. The Iron Chelating activity of the ethyl acetate extracts of the whole plant of C.
