Neem (Azadirachta indica A. Juss) oil (NO) was assayed against forty-eight isolates of Escherichia coli by standardised disc diffusion test and microdilution test. By molecular biology characterization, fourteen isolates resulted in diarrheagenic E. coli with sixteen primer pairs that specifically amplify unique sequences of virulence genes and of 16S rRNA. The NO showed biological activity aga...

Fruits of Balanites aegyptiaca (L.) Delile syn. B. roxburghii Planch (Family Balanitaceae) is considered as source of Ingudi of Ayurveda. It is a thorny tree with ovoid pulpy drupe type of fruit. In Ayurveda, Ingudi bark, leaf and fruits are said to be beneficial as blood purifier, diuretic, in leprosy, poisoning, ulcers, worm infestation, leucoderma, anorexia and constipation.

The present study elucidates the preliminary phytochemical analysis and High Performance Thin Layer Chromatography (HPTLC) fingerprint analysis of lawsone extract of the leaves of Lawsonia inermis (henna) and evaluates their regions and products based quantitative estimations. The lawsone content has been evaluated quantitatively in two plants samples collected from Rewa and Bhopal and one comm...

The present study was carried out to evaluate in vivo and in vitro anti-inflammatory potential of selected medicinal plants used in Indian traditional medication. The sequentially extracted plant samples as, Cissus quadrangularis, Plumbago zeylanica, Terminalia bellarica and Terminalia chebula in water, ethanol and hexane were evaluated in-vitro for COX-1 and 2 inhibitory and antioxidant activi...

Standardization of herbal drugs is the need of the hour as the use and practice of traditional herbal drugs has increased tremendously. The main objective of the present study is to standardize the root tubers of Aconitum heterophyllum as per pharmacopoeial testing protocol which include powder microscopy, physico-chemical screening, HPTLC fingerprinting and GC-MS analysis. Preliminary phytoche...

842 Journal of Chemical Education • Vol. 84 No. 5 May 2007 • www.JCE.DivCHED.org Thin-layer chromatography (TLC) is often used as a qualitative method. It can determine the number of components in a mixture, verify the identity of substances, monitor the progress of a reaction, or ascertain the effectiveness of a purification. Since TLC is so easy and practical, many chemists frequently use TLC...

Joint Fourier transform correlation is an analog optical signal processing technique capable of comparing several two-dimensional images. We show that selected spectral domain binary thresholds, obtained through simulation, signiicantly improve the performance of an optical implementation of the joint transform correlator. In doing so we establish empirically the existence of well deened optima...

Objective: To evaluate the hepatoprotective potential of methanol extract of roots and rhizomes of Smilax zeylanica L on carbontetrachloride (CCl4) induced hepatotoxicity in Wistar albino rats. Methods: Hepatotoxicity was induced in Wistar albino rats of either sex by administration of CCl4 0.5 ml/kg p.o. once a day for 7 days. The methanol extract of roots and rhizomes of Smilax zeylanica L we...

Mentha piperita and Citrus sinensis was an aromatic plants well known for its fragrance and distinct aroma. In this prospective study to evaluate the chromatogram detection of ethanol extract of Mentha piperita and Citrus sinensis with standard flavonoid marker eriocitrin by HPTLC technique. HPTLC chromatogram was developed in ethanolic extract of Mentha piperita, Citrus sinensis and standard f...
