ABSTRACT
Pithecellobium Jiringan (Jack) Prain is one of the medicinal plant sources that consist of Vitamin E. The seeds have many benefits for health due to vitamin E content which can be used as anti-oxidant, anti-high blood pressure and anti-aging. This research was carried out to identify the best parameter in order to obtain the high quality of vitamin E. The Vitamin E was extracted from P.Jiringan seeds by using Soxhlet extraction method. The parameters involved in this research are extraction time (4 to 8 hours) and type of solvents used (hexane, methanol and water). In this research, the highest overall yield was obtained using methanol as a solvent with 31.04% for eight hours extraction time. In order to identify and quantify the vitamin E present in the extracted oil Ultraviolet-Visible Spectrometer (UV-VIS) was used. The result obtained indicated that hexane is the best solvent to extract Vitamin E which has the highest concentration, 93.165 ppm for eight hours extraction time. Besides that, Gas Chromatography Mass Spectrometry (GC-MS) also was used in order to identify and quantify the other interest chemical constituents present in the extracted oil such as medicinal compound, noxious compound and also essential oil. The antioxidant activity from vitamin E that extracted from P.Jiringan seeds will be examined by using DPPH method. The expected result that will be obtain from the analysis is 200, 000 trolox equivalent (TE) per 100g of sample.

CONCLUSIONS
The extraction of Vitamin E from P.Jiringan seeds using Soxhlet Extraction was studied using two parameters which are solvent and time. From this study, the conclusion achieved is that hexane is the most suitable and effective solvent to extract Vitamin E from P.Jiringan seeds using Soxhlet Extraction, and that the longer the contacting time between solvent and the solute, the more yield and Vitamin E will be extracted. Meanwhile the antioxidant activity of vitamin E from P.Jiringan seeds can be determined accurately, conveniently, and rapidly using DPPH and the expected result that will be obtain from the analysis is 200, 000 trolox equivalent (TE) per 100g of sample.
With Egyptian woman being of one aspect of a multi-dimensional look at woman of the ancient times, woman who wrote classical literature in India also played an important part in providing future generations with stories and poems that were skillfully explained with suggestions, compared to the graphic descriptions that were seen in Ancient Egyptian love poems. One of the ancient Indian authors who perfected this technique is Vikatanitamba. Even though Vikatanitamba is similar in evoking passion within her poems, like the ancient Egyptians, she shows her able show her multi-dimensionality, but discretely. One poem where this was skill was shown was “As he came to bed”. Within the first line, she is able to subtly explain her dress falling off
When you buy food and drinks at the store do you really know what you are actually consuming? Have you ever considered how your food is produced and created? Is it healthy for you? I researched one of my favorite drinks, Welch’s grape juice, to see what is actually the content of it, and where it came from.
Anthocyanins, flavanols, flavanones,secoiridoids, phenolic acids, stilbenes, coumarins, and isoflavones form a large class of polyphenols, which are phenolic compounds. This study, however, focuses on one category of these phenolic compounds: phenolic acids. These particular compounds have been classified into two groups, namely hydroxycinnamic acids and hydroxybenzoic acids. The most common hydroxybenzoic acids are protocatechuic acid and gallic acid, while hydroxycinnamic acids include ferulic acid, coumaric acid, caffeic acid, chlorogenic acid, and sinapic acid, (Nigdikar, Williams, Griffin, & Howard). Unlike hydroxycinnamic acids, hydroxybenzoic acids usually occur at very low levels in some black radish, red fruits, and onions, accounting for about 10 ppm on a fresh weight basis. Protocatechuic ac...
WHEN Zhang Yimou made his directorial debut, Zhang Yimou made his directorial debut, Red Sorghum, in 1987, he was better known as a cinematographer whose talent had been crucial to the success of critically acclaimed films like Zhang Junzhao's One and Eight (1984, released 1987) and Chen Kaige's Yellow Earth (1984). Not only did Red Sorghum become a seminal film of the Fifth Generation, it also won the Golden Bear at Berlin in 1988, becoming the first mainland Chinese film ever to be awarded the highest honour at a major international film competition.
In conclusion, E. cava is a very interesting resource, due to the presence of unique phlorotannin derivatives with special bioactivities including ACE inhibitory activity. Ethanol enhances the extraction of phlorotannins specially dieckol from the brown seaweed E. cava. By contrast, in this study phloroglucinol derivative dieckol exhibited the strongest activity against ACE. With the results of this study we can suggest that the brown seaweed E. cava could be used in development of promising and potential functional food products. Moreover, it is expected that these findings will contribute to developing interests in basic research and potential applications of the phlorotannins in the relevant fields.
...tantly making efforts to discover new drugs and design better protocols for this cancer. Synthetic anticancer drugs kill the cancer cells but they are also harmful to the normal cells. Since, increase in the use of these drugs in cancer therapy leads to many side effects and undesirable hazards, there is a worldwide trend to go back to natural resources, i.e., traditional plant preparations which are not only therapeutically effective but are actually acceptable and economically within the reach of even the neediest people. The present study was undertaken to understand the effectiveness of the plants against hepatocarcinogenesis. Any practical solution in combating this dreadful disease is bound to be of paramount importance. Generally speaking, integrated approach to combine western and herbal medicines to treat cancer has proved to be relatively satisfactory.
The purpose of this experiment was to learn and preform an acid-base extraction technique to separate organic compounds successfully and obtaining amounts of each component in the mixture. In this experiment, the separation will be done by separatory funnel preforming on two liquids that are immiscible from two layers when added together. The individual components of Phensuprin (Acetylsalicylic acid, Acetanilide, and Sucrose as a filler) was separated based upon their solubility and reactivity, and the amount of each component in the mixture was obtained. Also, the purity of each component will be determined by the melting point of the component.
Determining the Concentration of the Cell Sap in Potato Storage Tissue Aim: To determine the concentration of the cell sap in potato storage tissue. By using Osmosis, determine what the sugar concentration of cell sap is. Prediction I predict that the potato segment in the distilled water will definitely gain in weight because the solution outside it has a much higher concentration of water then in the cell sap meaning Osmosis will occur and the potato segment take in water. I predict that 0.2M sugar solution will also gain weight because it still has quite a high concentration of water outside the potato. The potato in the 0.4M solution will gain weight but the potato in the 0.6M and 0.8M solutions will lose weight.
Performing this experiment, we used the technique called Acid-Base extraction to isolate Eugenol, which is one of the main ingredients of clove oil. Acid-Base extraction is the most efficient method for isolating organic component; it is efficient because it purifies the acid and base mixture based on their chemical identities. We have seen throughout this experiment that acid and base play an important role, when it comes to solubility in water. Our basic knowledge of acid and base is acid is a proton donor and base is a proton acceptor. This ideology helps us to understand why organic compounds are not soluble in water. When compounds tend to be insoluble, we have to use acid and base reaction, to change its solubility. The changes that occurred
Most people know about antioxidants and belive in them as preventers against cell damage, which in the most severe case can cause cancer. Almost all nutritions contain a certain amount of antioxidant – both chemical and/or biological. To measure the activity and amount of the antioxidants present in a sample, some distinctive but easy assays have been established. This paper will give a short overview of the ORAC (oxygen radical absorbance cacpacity) assay and compare it with other antioxidant assays.
Purpose: This lab gives the idea about the enzyme. We will do two different experiments. Enzyme is a protein that made of strings of amino acids and it is helping to produce chemical reactions in the quickest way. In the first experiment, we are testing water, sucrose solution, salt solution, and hydrogen peroxide to see which can increase the bubbles. So we can understand that enzyme producing chemical reactions in the speed. In the second experiment, we are using temperature of room, boiling water, refrigerator, and freezer to see what will effect the enzyme.
In this experiment, lipids from ground nutmeg are extracted using a combination of solvents and identify the lipids through chromatography. The purpose of using solvent combinations is to elute the lipids based on their polarity to binding of the silica gel. The chromatography is performed on a silica gel plate and the use of iodine to visualize the lipids. By calculating the Rf values for each compound and comparing them to the known lipids, we are able to distinguish the lipids within the grounded nutmeg.
...ls and soybean oils. But, in other research, it said that coconut oils have the highest concentration of active alpha tocopherol. Nevertheless, the goal of anti oxidants is to minimize free radicals damage because uncontrolled free radicals reactions can cause damage to cells structures and functions and Vitamin E posses the ability.

This clearly shows that the fruits and vegetables play a vital role in maintaining our good health. Fruits and vegetables are seasonal and grown in different parts of our country. They need to be stored for longer period and transported to different places. It makes necessary for us to find out whether there is any damage to the useful contents of the fruits and vegetable during the storage and transportation or due to some preservatives or other factors and what kind of nutrients, minerals, etc. are present in their juices. With this idea in mind, the project has been undertaken.
