ether and acetone for the separation of extract based on their polarity. The extract was run through Thin Layer Chromatography and the test confirmed the presence of polar and Non-polar compounds based on their mobility. Phytochemical screening was performed and presence of different secondary metabolites and compounds like saponin‚ reducing sugars‚ Steroids and terpenoids were confirmed. Antimicrobial activity was performed on various fractionated extracts against five pathogenic microorganisms (Bacillus

The use of plant extract for medical treatments is enjoying great popularity since 1990s when people realized that the effective life span of antibiotic is limited and over prescription and misuse of traditional antibiotics are causing microbial resistance.

The crude extract was then diluted in minimum amount of chloroform (2ml) and citrinin was estimated by thin layer chromatography (TLC) according to Razak et al.[16] Subsets of citrinin obtained were estimated by High performance Liquid Chromatography (HPLC). The control contained PDB broth and 10 μl of fungal suspension. Briefly‚ different volumes (1 to 5 µl) of sample extracts were applied to precoated

3.6. Conclusion Various solvent extracts from mahua flower and fruits showed varying degrees of antioxidant activity in different test systems in a dose-dependent manner. The antioxidant activity was correlated with the amount of total phenolics present in the respective extracts in each assay. 50% acetone proved to be the most efficient solvent for extraction of antioxidants from mahua as the related extract contained the highest amount of phenolic compounds and also exhibited the strongest antioxidant

tightly closed ready for expression. Preliminary Test for the Determination of Plant Constituent It was done to conduct a phytochemical screening of a particular plant and the identification of plant constituent present in its extract. Preparation of the Plant Extract Place 10g of dried ground plant sample or 20g of fresh sample in an erlenmeyer flask covered with a funnel. To this‚ add 100ml of 80% ethyl alcohol. Place the flask over a hot water bath and reflux for an hour. If exhaustive extraction

Explore the theme of danger in Blood River and Heart of darkness. ‘Abandoned’ ‘blind’ ‘darkness’ ‘challenges’ ‘overwhelmed’. These five words are the best words in both of these extracts do describe what is happening in both texts. The first noticeable thing in both extracts Blood River from page 216 to 218 and heart of darkness 48- 50‚ is the link of the theme of danger to the settings being used in both texts. Evidence of this is in heart of darkness when the text says” the night came suddenly

temperatures. Different solvents provided extracts with different colour values at varying temperatures. At 50⁰C‚ the maximum colour value was found to be in the extract obtained using ethanol as the solvent. As shown in Figure 4.5‚ it could be clearly analyzed that different colour values are obtained on extraction with different solvents. Ethanol gave the maximum colour value i.e. 308.6; chloroform gave a slightly less value of 296.6; followed by methanolic extract giving 249.3

number: 730078 Introduction In this two extracts we going to be analysing the way this two extracts correspond with each other. After reading both the extracts I notice both extracts belong to the same genre‚ how the general tone in both extracts is sad‚ bitter and emotional. This is supported by the writer’s phrases‚ diction and register. Extract 1 describes the ruthless hangings of rebels of German and there use of emotive language it focuses on the victims. Extract 2 the detail on the hanging of a man
