Mukia Maderaspatana Antioxidant Properties

Mukia Maderaspatana Antioxidant PropertiesPlants turn over the ability to synthesize a wide variety of chemical compounds that be recitationd to perform important biologic functions and to defend against attack from predators. Mukia maderaspatana (L.)M. Romer, is an one-year monoecious climber, belonging to Cucurbitaceae family. This plant specify many medicinal properties much(prenominal) as constipation, cough, vertigo, ardent sensation, dyspepsia and dental pain.. In this larn, ascorbic point means from fresh leaves and fruits were carried appear. Also, the phytochemical analysis such as Total flavonoid, center phenolics substances of the plant were characterized, and found that leaves of M.maderaspatana is rich in ascorbic dosage, an antioxidant than that of fruits and also contains equal measurement of phenolics and flavonoid contents in leaves as comp ard to fruits.Keywords Mukia maderaspatana, Phytochemical activity, Antioxidant activity.IntroductionPlants (fru its, vegetables, medicinal herbs, etc.) whitethorn contain a wide variety of free radical scavenging molecules, such as phenolic compounds (e.g. phenolic acids, flavonoids, lignans, tannins), nitrogen compounds, vitamins, terpenoids (including carotenoids), and some other endogenetic metabolites, which ar rich in antioxidant activity ( Zheng and Wang, 2001 Cai et al., 2003). Phytochemicals ease up in plants surrender been shown to have diverse biological activities like cardioprotective, cancer legal profession and inhibiton of fig out resorption. One of the most common activities of the phytochemicals is the antioxidant .(B.R.Srilatha and S.Ananda., 2012). The join antioxidant activity of plant foods is the go forth of individual activities of each of the antioxidant compounds present such as vitamin C, carotenoids, and phenolic compounds, the latter(prenominal) being the major phytochemicals responsible for antioxidant activity of plant corporeals (Javanmardi, Stushnoff, Locke, Vivanco, 2003)Plants are the earthy source for many biochemicals, fragrance, food coloures ,flavors and medicines with less side affects. Most rich phytochemicals are the products of secondary metabolism .The use of plants as medicines predates written tender history. All the plants produce chemical compounds as a part of their blueprint metabolic activity. The scientific interest in identifying novel natural antioxidants for use in foods has considerably increased in recent years, because the use of unreal antioxidants as food additives is limited by specific regulations in variant countries, established on the basis of their safety.(Spiridon Kintzios et al.2010). many a(prenominal) plants synthesize substances that are reclaimable to the maintenance of health in humans and other animals. Compounds like flavonoids, phenolics are widely distributed in plants fulfilling many functions. They are most common grouping of polyphenolic compounds in human diet, and are k nown for their antioxidant activities. Pharmaceuticals and food manufactures have go away interested in these compounds for their medicinal properties especially their putatitive role in inhibiting cancer or cardiovascular diseases. Antioxidant plays an important role in the living establishment and it prevents the oxidative damage that may result in cancer, cardiovascular diseases and diabetes. (Sangilimuthu Alagar Yadav et al.,2012) Ascorbic acid , which is commonly known as vitamin C is common antioxidant . Ascorbic acid present in medicinal plants has attracted the attention of many researchers because of the wide range of their biological activities. (Mallika Jainu et al., 2008). Many studies have correlated high intakes of vitamin c, with low rates of cancer, specially cancers of mouth, larynx and esophagus. Use of plants to treat diseases is almost universal among non industrialized societies, and are often more affordable than purchasing expensive modern pharmaceuticals. Many of the pharmaceuticals currently available to physicians have long history of use as herbal remedies including aspirin, digitalis, quinine and opium.Leaves and Fruits of Mukia maderasapatanaMelothria madraspatana (Syn. Mukia maderaspatana L.) is an annual climber with hair shoots. It is an edible plant typically low in calories, low in fat, high in dietary fibre, high in iron and calcium and very high in phytochemicals such as Vitamin C, vitaminK, carotenoids, lutein, folate and polyphenolics compounds such as flavonoid etc. The all plant is useful as it has valuable medicinal properties, cough, dental pain, burning sensation, and ayurvedic properties such as Rasa, Guna,Virya, vata, pita. In scientific literature M. maderaspatana has been shown to be anti- insurgent, anti arthiritic Immunomodulatory, anti platelet ,hepato protective and antimicrobial. (B.R.Srilatha and S.Ananda., 2012). So the present study was carried out to evaluate the total phenolics, flavonoid and ascorbi c acid contents in the leaves and the fruits of the plant.Materials and methodsPlant material M.maderaspatana were collected from vellore institute of technology (VIT) garden, vellore, Tamilnadu, State of India.ChemicalsAscorbate, Trichloroacetic acid, DNPH (2,4 Dinitro phenylhydrazine) reagent, Thiourea solution, FC ( Folin ciocalteau)reagent, Catechol, Sodium change, Ethanol, Quercetin, Aluminium Chloride, grand ethanoate. mind of Ascorbic acidThe amount of ascorbic acid present in leaves and fruits of M.maderaspatana was estimated by method of (Roe and Keuther1943).Fresh leaves and fruits (1gm) were homogenized with 10ml of 4% TCA and centrifuged at 2000 rpm. The supernatant obtained was treated with relish of activated charcoal for 10 min. Centrifugation was repeated and clear supernatant was obtained. two diametric aliquots of supernatant (0.5 and 1.0ml) were taken as test sample . The gaudiness was made upto 2.0ml with 4% TCA ,0.5ml of DNPH, 2drop of 10% thiourea soluti on was added and incubated for 3 hour at 37c . 2.5ml of 85% sulphuric acid was added and absorbance was read at 540 nm against blank . Ascorbate was used as standard. The ascorbic acid was expressed as mg uniform per gram of deplume.Preparation of ethanolic extract for phenolicsThe leaves and the fruits of the plant were fill in dried and powdered in the grinder. The powder leaves and fruits (25gm) was extracted with 85% ethanol (100ml) and unploughed overnight. The ethanol was evaporated next day using water bath and the symmetry was dried and used for further analysis.Estimation of phenolicsThe total phenolic content present in leaves and fruits were assayed by (Mallick and Singh 1980). 10mg of plant extract was dissolved in 1ml of 80% ethanol. Further dilution were made up to 1mg /ml and different concentrations ( 10l,50l,100l and 250l) were taken and made up to 3ml with distilled water. 0.5ml of Folin ciocalteau reagent was added and incubated for 3min at RT. 2ml of sodium carbonate was added and kept in boiling water bath for 1min, cooled and absorbance was measurable at 650 nm against blank .Catechol was used as standard. The total phenolic content was expressed as Catechol equivalent in mg per gram of extract.Estimation of flavonoidsThe total flavonoids contents present in leaves and fruits were assayed by (Chang et al.,2002).10mg of plant extract was dissolved in 1ml of 80% ethanol, further dilution were made upto 1mg/ml and different concentrations ( 10 l,50l,100l and 250l )were taken, 0.1ml of 10% aluminium chloride and 0.1ml of 1M potassium acetate and reaction mixture were made upto 3ml with distilled water. After 30min incubation at RT, the absorbance was measured at 415nm, against blank. Quercetin was used as standard. The flavonoid content was expressed as Quercetin equivalent in mg per gm of extract.ResultsStandard graphs of Ascorbate, Catechol and Quercetin for Ascorbic acid, Phenolics and Flavonoid respectively are shown below, and The total content of these phytochemicals, present in M.maderaspatana were assayed using these standard graphThe amount of Ascorbic acid, Total Phenolics and Flavonoids present in the leaves and fruits were investigated. The amount of Ascorbic acid is expressed as mg ascorbate /g. graphical record1 (Standard curve compare Y= 0.007 x, r2 = 0.992), The total amount of phenolics is expressed as mg Catechol/g. Graph 2 ( Standard curve equation Y = 0.029 x, , r2 = 0.995) and The total amount of Flavonoid is expressed as mg Quercetin /g. Graph 3 (Standard curve equation Y = 0.012 x, r2 = 0.993) is tabulated below.DiscussionMedicinal plants are reported to be rich in antioxidants, namely polyphenols, flavonoids, vitamin A, C, E and several(prenominal) other constituents, which are necessary for maintaining good health and useful for redress purposes against various diseases (Scalbert, Johnson, Saltmarsh, 2005) Medicinal plants are gaining a lot of importance as an alternate medicine against therapy and prevention from various diseases.(Raj Kumar Dutta et al.,2012). The result of present study in quantitative analysis of Ascorbic acid in leaves of Mukia maderaspatana were high (99.046 1.413 g/g) comparatively to that of fruits, (24.52 1.43 g/g) and various studies have revealed that ascorbic acid is an antioxidant vitamin that acts synergistically with tocopherol to relate antioxidant function in chronic disease states (Bruno et al.,2006 Traber Stevens, 2011, Nuri Andarwulan et al .,2012). And Total Phenolics (31.08 0.5291 g/g) and Flavonoid (25.388 0.0174 g/g) contents were also high in leaves to that of fruits (14.97 1.127 g/g ),( 6.47 0.012 g/g ) respectively .In the whole, leaves showed the higher amount of contents as compared to that of the fruits, and the antioxidant property of ascorbic acid were high when compared to phenolics an flavonoid contents in M.maderaspatana plant.ConclusionsThe data presented in the study showed that Mukia maderaspatana is ri ch in antioxidant properties, especially Ascorbic acid, which is necessary for the treatment and prevention of scurvy and reduce neurological defects. The plant also contain comely amount of flavonoid and phenolic content, which have anti-germ activities, anti tumor and anti inflammatory properties with reduced risk of heart diseaseand many chronical diseases. Thus find out the antioxidant activities from M. maderaspatana could be valuable for pharmaceuticals and even for the food industries as they are abundantly found.
