A SIMPLE METHOD FOR THE CHARACTERIZATION OF ANTIOXIDANT PROPERTY OF DIFFERENT EXTRACTS OF BARK OF GETHI (BOEHMERIA RUGULOSA)

The antioxidant property of methanol, acetone and acidified methanol extracts of the bark with three different concentrations 0.5mg/ml, 5 mg/ml and 10mg/ml was determined by phytochemica[r]

CONCLUSION
The case study presented reveals that mean esti- mators under systematic sampling can remarkably be improved in precision by poststratification when strata comprise a large number of small connected subareas. The larger connected subareas are the<[r]

Plant cell cultures
General
The number of laboratories dealing with plant cell cultures has increased continuously in the some few years. In 1972, 940 scientists from 41 countries belonged to the “international association for plant tissue cultures”. In 1980[r]

The analysis of modular gene co-expression networks is a well-established method commonly used for discovering the systems-level functionality of genes. In addition, these studies provide a basis for the discovery of clinically relevant molecular pathways underlying different diseases and conditions[r]

As plants have substances of medicinal values, they are used to treat number of diseases since long time. They had minimal or less side effect on human beings. In the present study, the antimicrobial and antioxidant properties of the flower extract of Nerium oleander was evaluated as a remedy for pa[r]

The aim of the present study is to determine the in vitro antimicrobial activity of various extracts of Muntingia calabura (Elaeocarpaceae) leaves against a selected panel of microorganisms. Antimicrobial testing was carried out using the agar well diffusion assay method.

We see that the rate of convergence of the iteration process performed by the Newton–Kantorovich method is significantly higher than that performed by the method of successive approximations (see Example 2 in Paragraph 16.5.3-4).
To estimate[r]

Biologically active compounds usually occur in low concentration in plants. An extraction technique is that which is able to obtain extracts with high yield and with minimal changes to the functional properties of the extract required 20 . Extract yi[r]

Some extracts of medicinal plants have been proven to be beneficial in treating a number of diseases for centuries such as treating diabetes, antioxidant, anti-inflammatory, antibacterial, etc. This study aimed to evaluate the effect of extracts from several herbal plants, such as Gymnema sylvestre,[r]

1. INTRODUCTION
Bark beetles are one of the major threats to coniferous forests. These insects use trees as a substrate during their life cycle. During periods of endemic population levels, bark-beetles restrict their attacks to weakened or dying trees.[r]

ABSTRACT
The effect of these factors and solvent extraction of tannin from the bark in water solvent has been studied. The above factors and the solvent is determined by the
