INTRODUCTION: India has one of the oldest, richest, and most diverse traditions associated with the use of medicinal plants 1. Plants have been used extensively for the treatment of various ailments. According to the World Health Organization (WHO), around 85-90% of the world’s population uses herbal medicines 2. Plants used in traditional herbal medicines may not be as useful as asserted or may have therapeutic properties in addition.
Therefore, proper scientific understanding is requiredto explore the medicinal plants for curative purpose 3. Due to the lack of inadequate synthetic drugs WHO has recommended the evaluation of physicochemical and phytochemical parameters of medicinal plants for its efficacy. These parameters help in identification and authentication of the plant material 4.
Flacourtia jangomas (Lour.) Raeusch (family Salicaceae) is commonly known as Paniala or Indian plum. Leaves are alternate, spirally arranged, rarely ovate-lanceolate, and pale pink when young. The fruits are dark-red when ripe. Traditionally, various parts of the plant are used for the treatment of numerous ailments. Sasi et al. reported that the leaves are astringent and stomachic. The fruits are used to overcome various disorders such as quench thirst, biliousness, fevers, stomach upset, and diarrhea 5. Therefore, the aim of the present work was to ascertain chemical standards like physicochemical and phytochemical testing of the leaves and fruits of Flacourtia jangomas (Lour.) Raeusch.
MATERIALS AND METHODS:
Plant Material: Flacourtia jangomas (Lour.) Raeusch was collected from Bellikoth, Kasargod District of Kerala, India. It was taxonomically identified and authenticated by Dr. T. S. Swapna, Professor, and Head, Department of Botany, University of Kerala, Kariavattom, Thir-uvananthapuram, and the voucher specimen was deposited with Accession number KUBH10169. The voucher specimen of the plant F. jangomas (Lour.) Raeusch was preserved in the Herbarium of Department of Botany, University of Kerala, Kariavattom.
Physicochemical Analysis: The leaves and fruits of F. jangomas were collected, cleaned and shade dried for about 3 weeks and 7 weeks, respectively. Dried leaves and fruits were then homogenized to obtain coarse powder and stored in an airtight container for further use.
The various physicochemical parameters such as moisture content, ash values including total ash, acid insoluble and soluble ash, water-soluble and insoluble ash and sulphated ash, water-soluble extractive value, alcohol soluble extractive value, foaming index, swelling index, and pH of powdered plant material were determined by the methods described in Indian Pharmacopoeia 6 and WHO guidelines 7.
Fluorescence analysis: The leaf and fruit powder of F. jangomas was subjected to fluorescence analysis, after treating with various chemical reagents like methanol, chloroform, ethanol, diethyl ether, petroleum ether, acetone, benzene, glacial acetic acid, sulphuric acid, hydrochloric acid, nitric acid, 1N sodium hydroxide and distilled water against visible and UV light (312 nm) 8.
Phytochemical Screening:
Qualitative Analysis: For preliminary phyto-chemical screening, the powdered leaf and fruit material were extracted with methanol in Soxhlet apparatus, and the solvent extract was concentrated using a rotary vacuum evaporator and stored at 4ºC until further use. The extract thus obtained was subjected to different qualitative analyses to discern the bioactive components. The presence of alkaloids, glycosides, tannins, flavonoids, fat and fixed oils, steroids, phenol, quinones, lignin, resins, saponins, coumarins, chalcones, proteins, and carbohydrates were determined according to the Harborne method described by Joshi et al., 9 and Irum et al.,10.
Quantitative Analysis:
Determination of Total Phenolic Content: The total phenolic content was determined by the method of Jose and Anilkumar 11 with slight modifications. Gallic acid was used as a standard, and the total phenolics were expressed as mg/g gallic acid equivalents (GAE). Briefly, 1 ml of a standard solution of different concentrations (10-100 µg/ml) of gallic acid and 1 mg/ml of plant extract were prepared in methanol. 0.5 ml of sample mixed with 2.5 ml of a 10% Folin-Ciocalteu’s reagent and 2ml of 7.5% sodium carbonate. The tubes were covered and allowed to stand for 30 min at room temperature, and the absorbance was read at 760 nm spectrometrically.
Determination of the Total Flavonoid Content: Total flavonoid content was determined using the Aluminum chloride method of Jose and Anilkumar 11 with slight modifications. In this method quercetin was used as standard, and flavonoid contents were measured as quercetin equivalent (QE). Briefly, 1 ml of standard solution (100-500µg/ml) and 1mg/ml extract were prepared in methanol. 0.5 ml of sample was taken into a test tube containing 4ml of distilled water. 0.3 ml of 5% NaNO2 added to the test tube. After 5 min, 0.3 ml 10% AlCl3 and 2 ml of 1M NaOH were added to the mixture and made up the volume to 10 ml with distilled water. The absorbance was noted at 510 nm using a UV-Visible spectrophotometer. Standard was prepared in the same manner.
Determination of the Total Tannin Content: The total tannin content was determined by Folin-Ciocalteu method of Chandran and Indira 12 with slight modifications. Tannic acid was used as standard, and tannin content was expressed as mg/g of tannic acid equivalents (TAE). Briefly, 1 ml of standard solution (10-150 µg/ml) was prepared in distilled water, and 1mg/ml extract was prepared in methanol. 0.5 ml of sample was taken into a test tube; containing 7.5 ml of distilled water.0.5 ml of Folin-Ciocalteu’s phenol reagent and 1 ml of 35% sodium carbonate solution were added to the test tube and diluted to 10 ml with distilled water. The mixture was shaken well and kept at room temperature for 30 min. Standard was prepared in the same manner as described earlier. Absorbance for test and standard solutions were measured against the blank at 700 nm with an UV/ Visible spectrophotometer.
Determination of Alkaloid Content: Alkaloid content was determined gravimetrically by the method of Roghini and Vijayalakshmi 13. One gram of the sample was taken in a beaker. 200 ml of 10% acetic acid in ethanol was added to it and left as such for 4 h. It was then filtered and the extract was concentrated on a water bath to one quarter of the original volume. Concentrated NH4OH was added drop wise to the extract until the precipitation was complete. The whole solution was left to settle and the precipitate was collected and washed with dilute NH4OH and then filtered. The residue is the alkaloid, which was dried and weighed.
GC-MS analysis: The phytochemical investigation of methanolic extract of both leaf and fruit of F. jangomas was performed on Shimadzu GC-MS (Model Number: QP2010S) instrument and GC-MS Software - GCMS Solutions was used for analysis. Experimental conditions of the GC-MS system were as follows: Rxi-5Sil MS column, dimension: 30 Mts, ID: 0.25 mm, film thickness: 0.25 μm. A flow rate of mobile phase (carrier gas: He) was set at 1.0 ml/min. In the gas chromatography part, the temperature program (oven temperature) was 80 °C raised to 280 °C at 5 °C / min, and injection volume was 1 μl. Samples dissolved in methanol were run fully at a range of 50-500 m/z and the results were compared by using Wiley Spectral library search program (Wiley 8) and NIST mass spectral database (NIST 11).
EDS Analysis: The semi-quantification elemental analysis of leaf and fruit of F. jangomas was performed using Scanning Electron Microscope- Energy Dispersive Spectrometer (SEM-EDS) equipment. OXFORD INCA software was used for Digital Imaging and Spectral Collection.
Statistical Analysis: Values have been expressed as mean ± standard deviation (n=3). Statistical comparisons of physicochemical and phyto-chemical parameters F. jangomas leaf and fruit were made with Student t-test
RESULTS AND DISCUSSION:
Physicochemical Analysis: Evaluation of physicochemical parameters is important in identifying adulteration or inappropriate handling of drugs 4. The physicochemical profile of leaf and fruit of F. jangomas is shown in Table 1.
