ARTICLE INFO Article history Received 13/05/2013 Available online 30/05/2013 ABSTRACT India is sitting on a gold mine of well-recorded and traditionally well practiced knowledge of herbal medicine. General phytochemical screening of Citrus sinensis (Orange) belonging Rutaceae family revealed the presence of flavones glycoside. The aim of this study is to identify and characterize the bioactive principle compound (Hesperidin) from the peel of C. sinensis fruit. It has wide folk medicinal uses. The isolation and characterization of phytoconstituents was done from the alkaline (KOH) extract of peels.

2 INTRODUCTION Throughout the ages, plants have been used by humans as a source of food, cosmetics, medicine, clothing and even shelter. Plant products also play an important role in the health care systems of the remaining 20% of the population who mainly reside in developed countries [1]. The plants of the genus citrus (Rutaceae) are widely distributed in most tropical and subtropical countries. Hesperidin, a flavanone-type polyphenolic bioflavonoid, is found abundant in the peel and membraneous parts of orange peel and other citrus fruits. Hesperidin is an antioxidant that enhances the action of vitamin C (ascorbic acid) to lower cholesterol levels. Hesperidin is comprised of the flavanone hesperitin and the disaccharide rutinose and has been reported to have many biologically important properties, including anti-inflammatory, antimicrobial, anticarcinogenic, antioxidant and capillary strengthening effects it is also known to have pharmacological action as an antiinflammatory, antihistaminic, and antiviral agent [2-5] as well as flavoring agent. MATERIAL AND METHOD 1) Collection of Plant Material: - The fruits of Citrus sinensis (Orange) were purchased from local market of Jabalpur, M.P and they were peeled off and peels were dried under shade. 2) Isolation of Hesperidin: - Hesperidin was isolated by the method given in literature and reference book with little modification. 2.1) Conventional Method: - The dried orange peels (250gm) were macerated with 800ml of aq. alkaline solution (10% KOH) ph 8-9 for overnight (fig. 1), After complete maceration the mixture was filtered by large Buchner funnel and filtrate was evaporated to make it syrupy mass [6]. Fig. 1 Maceration of orange peel 2.2) Modern Method: ml petroleum ether (40 60 C) is filled in a 250 ml round bottom flask with magnetic stir bar. 250g dried and powdered orange peel are placed in the extraction sleeve of a Soxhlet extractor and covered with a little glass wool. A reflux condenser is put on the Soxhlet extraction unit, and then the reaction mixture is stirred and heated for 4 hours under strong reflux (fig. 2). The petroleum ether extract is discarded. In order to remove the adherent petroleum ether, the content of the extraction sleeve is laid out in an extensive crystallisation dish. Afterwards the substance is placed again in an extraction sleeve and, like before, Page3893

3 but with 800 ml methanol, extracted unless the solvent leaving the extraction sleeve is color less (1 to 2 hours) [7]. Fig. 1 Soxhlation of orange peel After complete Soxhlet extraction and maceration the filtrate was then acidifying (ph 3-4) with 6% acetic acid, Keep the concentrated residual liquid in refrigerator (4-6 C) over night when a solid crystalline substance appears (fig. 3 and 4). It was again filtered and the crude hesperidin was separated out on Buchner funnel as amorphous powder. The hesperidin was further characterized and identified according to various physicochemical parameters [8]. The compound was characterized according to various factors. The yield of hesperidin was analyzed by graphical representation (fig. 5) Fig. 3 Hesperidin by conventional method fig. 4 Hesperidin by modern method Page3894

4 Yield 2.35 gm 1.8 gm conventional method modern method Fig. 5 Graphical representation of yield of hesperidin RESULT AND DISCUSSION The compound was isolated from maceration and Soxhlation shows a positive ferric chloride and Shinoda test for flavonoids, indicating that the compound may be a flavonoid [9-10]. It is yellow brown in color, characteristic aromatic in odor, with melting point 257 C. There are two spots were observed in thin layer chromatography of crystal using n-butanol: Acetic Acid: Water (3:1:1) as mobile phase at 0.20 and 0.62 (fig. 6), physical and analytical characters are listed in table 1 and 2 respectively. The yield of hesperidin from two different methods is 1.80 gm and 2.35 gm respectively.
