Scientific Study from the year 2017 in the subject Agrarian Studies, grade: 1.5, Mar Augusthinose College, language: English, abstract: In our society cholesterol related diseases are increasing day by day. The major reason for this is our eating habit or food habit. Eating foods containing trans fats, which are often found in fast food and commercially baked breads, cookies, and snack foods. It was observed that while peoples taking the fruits of Garcinia gummi-gutta in their food preparations have low cholesterol level. Some peoples are eating boiled fruits and drinking water in which the fruits peels are boiled in order to reduce the cholesterol level. This study was carried out to explore the phytochemical constituents of the solvent extracts of Garcinia gummi-gutta fruit and in vitro analysis of its cholesterol lowering effect. The cholesterol lowering effect was carried out in vitro using common fatty food materials like ghee, fats of pork and chicken, hen egg and cod liver oil. Each food materials were treated with extract and incubated for a number of days and each day the cholesterol level was estimated by Zak's method. From the data, pork and chicken fat, egg yolk and ghee shows significant reduction in the cholesterol level. From the present study it can be concluded that the constituents present in the extracts may be responsible for the cholesterol lowering activity.

Scientific Study from the year 2016 in the subject Biology - Micro- and Molecular Biology, grade: 1.5, Mar Augusthinose College, language: English, abstract: Citrus, one of the major genes of Rutaceae family and most economically important fruit tree and widely cultivated throughout the country. The Citrus have high nutritional value and medicinal value. Honey and lemon-honey are traditional remedies in the Middle East and China and for many centuries and have been used in the treatment and prevention of the common cold and various upper respiratory tract infections. Three types of honey were collected; 'Cheruthen'-produced by bees belongs to the Trigona irridipennis species; Vanthen'- produced by bees belongs to the Apis indica species; 'Kattutthen'- produced by bees belongs to the Apis dorsata species. The antibacterial activites of honey samples and lime juice were tested aganist Bacillus, Klebsiella, E.coli, Staphylococcus and Micrococcus. The result showed that the samples have differnt antimicrobial activity. Antimicrobial activity of Cheruthen against Klebsiella species showed a zone of inhibition of 10.1 0.73 mm, when 100 l of Cheruthen is applied. When 200 l of Cheruthen is applied the zone of inhibition was 30.1 0.23 mm. Antimicrobial activity of Cheruthen against E.coli showed a zone of inhibition of 10.1 0.13 mm, when 100 l of cheruthen is applied. When 200 l of cheruthen is applied the zone of inhibition was 30.2 0.23 mm. Also the phytochemical examination of lime juice and honey samples showed that different types of phytochemical substances are present in both lime juice and different types of honey samples. Further studies are required to reveal the role of each phytochemical and its contribution to the antimicrobial properties of the samples included in this study.

Scientific Study from the year 2017 in the subject Agrarian Studies, grade: 1.5, Mar Augusthinose College, course: Biochemistry, language: English, abstract: Aqueous extract of the fruit pulp of Averrhoa carambola (star fruit) were evaluated for cholesterol lowering effect, in vitro, against various fatty food materials. Peoples are consuming food items made out of chicken, beef, mutton, egg and fish which contains large amount of fat. This study aims to analyze the effect of Averrhoa carambola in reducing the cholesterol level in this fat compound using water extract of the pulp. For this fatty food samples like egg yolk, pork fat, chicken fat , ghee and cod liver oil were treated with the extract and cholesterol level was estimated by Zak s method for a period of time. Phytochemical constituents present in water extract of Averrhoa carambola Linn. pulp includes alkaloids, saponins, steroids, phlobatannins, carbohydrate, terpenoids, phenols, coumarins, flavonoids and leucoanthocyanins. The in vitro cholesterol lowering effect of Averrhoa carambola pulp extract shows a positive result on reducing chicken fat, ghee and egg yolk. But in case of cod liver oil no beneficial change was observed.

Scientific Study from the year 2016 in the subject Biology - Micro- and Molecular Biology, grade: 1.5, Mar Augusthinose College, language: English, abstract: Citrus, one of the major genes of Rutaceae family and most economically important fruit tree and widely cultivated throughout the country. The Citrus have high nutritional value and medicinal value. The three varieties obtained from various districts in Kerala were used in this study. The phylogenetics is the study of the evolutionary relationships among different species which have common ancestor. These relationships are shown in the form of phylogenetic trees composed of branches which indicate the descendents and nodes which represent the most recent common ancestors. In order to assess the phylogenetic relationships among the 6 samples belongs to the 3 Citrus species (Citrus aurantifolia, Citrus maxima, Citrus limon) a chloroplast gene rbcL and matK was successfully amplified and sequenced. For this study DNA was extracted by using CTAB method. This extracted DNA was analysed by spectrophotometry method for checking purity of DNA.The samples were gel electrophoresed by 1% agarose gel electrophoresis at 80 volts. After electrophoresis the gel is examined in gel documentation system. The DNA band was observed under UV light looking florescent Orangish red colour. The extracted DNA was amplified by PCR method and PCR sample was applied for electrophoresis for checking DNA bands. PCR sample were purified sent for sequencing. Sequences obtained were subjected to editing and alignment using ClustalW programme of Bio Edit and phylogenetic analysis was performed using MEGA software. High similarity observed between selected verities. The locally collected gene sequence-based phylogeny presented here provides support for the early studies of speciation within the Rutaceae. An understanding of the main phylogenetic relationships between Citrus species will help to fine-tune the taxonomy of Rutaceae.

Scientific Study from the year 2016 in the subject Biology - Micro- and Molecular Biology, grade: 1,5, Mar Augusthinose College, language: English, abstract: The classification of the Musaceae (banana) family species and their phylogenetic inter-relationships remain controversial, in part due to limited nucleotide information to complement the morphological and physiological characters. In this work the phylogenetic relationships within the Musaceae family were studied locally using 3 species. DNA sequences obtained from nine unlinked nuclear genes. Musa species grow in a wide range of environments and have varied human uses, ranging from the edible bananas and plantains of the tropics to cold-hardy fibre and ornamental plants. There are five taxonomic sections in the genus Musa, two of which contain edible bananas. For studying phylogeny of locally collected Musaceae (banana) family varieties using rbcL gene and matK gene. For this study DNA was extracted by using CTAB method. This extracted DNA was analysed by spectrophotometry method for checking purity of DNA. The samples were gel electrophoresed by 1% agarose gel electrophoresis at 80 volts. After electrophoresis the gel is examined in gel documentation system. The DNA band was observed under UV light looking florescent orange red colour. The extracted DNA was amplified by PCR method and PCR sample was applied for electrophoresis for checking DNA bands. After all this analysis PCR sample send for DNA sequencing for checking the nucleotide. Comparing the sequenced nucleotide for checking phylogeny of locally collected banana varieties. The locally collected gene sequence-based phylogeny presented here provides support for the early studies of speciation within the Musaceae. An understanding of the main phylogenetic relationships between banana species will help to fine-tune the taxonomy of Musaceae.
