RESEARCH DESIGN AD METHODOLOGY
Laboratory Procedure:1. Collection and. Preparation of the Sample Fresh radish were bought in Biñan, Laguna Public Market. The
radish were washed with running water and drained immediately after collection and then air dry for two days then cut into small pieces as possible and reserved it for the next procedure.
1.1 Moisture Determination A clean and dry crucible was weighed and placed with ____ g of Radish and
weighed again. The porcelain crucible with radish sample was heated for about thirty minutes. After heating, the crucible with the radish sample was allowed to cool in the desiccators for l5 minutes. After cooling the crucible with the radish sample was weighed again and then the moisture content was computed.
1.2 Ash Determination The accurately weigh quantity of the ground drug representing
from ___ g of dried radish sample in tarred plain crucible and incinerate at low temperature, not exceed very dull redness, until free from carbon. Cool and determine the weight of
the ash. If the carbon free ash cannot be obtained in this way, the charged mass was exhausted with hot water, and then the insoluble residue was collected on the ashless filter paper. The residue was incinerated and filtered until the ash is nearly so, then the filtrate was added and evaporated to dryness and was heated a whole to a dull redness. If again the carbon free ash cannot be obtained by this manner the crucible was cooled. Fifteen milliliters of alcohol was added to break up the ash with a glass rod, burned of the alcohol, and again was heated with the whole to a dull redness. The ash was cooled, weighed and calculated the percentage of the total ash from the weight of the plant sample taken.
2. Method of Extraction The Researcher use the Maceration method using 80% ethyl alcohol
and continuous extraction using the rotavap apparatus. From those extractions, the researcher computed the
glycoside extract.
3. Preliminary Screening for Glycosides
Five grams of the weighed plant extract is added with three milliliter (3 ml) of lead acetate T.S., and was filtered to remove the precipitate. The first procedure was repeated until no precipitate is formed. Five drops (5 gtts.) of basic lead acetate was added to the
final filtrate. Formation of white precipitates indicates the presence of glycosides.
4. Partial Purification of Glycosides The alcoholic extract obtained from the continuous extraction was
placed in a tarred evaporating dish and was heated in a water bath until dried. The dried extractive was treated with hot water, stirred and then transferred in a beaker. More hot water was added into a beaker to completely dissolve the extractive and then filtered. The filtrate was treated again with lead acetate solution to remove any unwanted constituents and filtered. This process was repeated several times until it no longer gives precipitate when treated with one to two drops (1-2 gtts.) of ferric chloride T.S. and the filtrate obtained was placed in a tarred evaporating dish and heated in a water bath until dried to obtain the glycoside extractive.
4.1Percentage Yield of the Semi-purified Glycoside Extract. A portion was computed for the percentage yield. The weight of the
evaporating dish with the residues was subtracted to the weight of the evaporating dish alone to get the weight of the residues alone. The weight of the residues was then divided to the weight of the plant sample used then multiplied by 100 for the purpose of determining the percentage yield of the plant extract.
4.2 Physical test4.2.1 Organoleptic Test.
After obtaining the glycosides, color, odor and the appearance or texture was observed and noted. 4.2.2 Solubility Test. A small amount of the semi-purified glycosides extracts were
divided into four test tubes labeled each as “A, B, C, D”. Each test tube contains five milliliters (5ml) of water, petroleum ether, ethanol and chloroform. The degree of solubility of glycosides was observed and recorded
4.3 Chemical Test.
4.3.1Screening of Anthraquinone Glycosides
A)Borntrager Test B)Modified Borntrager Test4.3.2 Screening for Flavonoids A)Bate-Smith and Metcalf Test for Leucoanthocyanins
B)Wilstatter “Cyanidin” Test.
5. Microbiological Test for determining the Antifungal Property of Radish extract
The following are the culture media, microorganism, standards and apparatus used in the microbiological screening: Saboraud Dextrose Agar (SDA) is the culture media; the fungi Trichophyton mentagrophtes; the standard antibiotic Canesten and the apparatus used are the Petri dishes, pipette cork borer and vernier caliper.
5.1Test Organism: Fungi (yeast): Candida albicans and Trichophyton mentagrophytes5.2 Preparation of inoculums - Preparatory to the assay, the
surface of agar slants contained in the test tubes are inoculated from a recently grown slant. After incubation at room temperature for eighteen to twenty-four hours, a stock suspension is prepared by collecting the surface growth in about 10 ml of sterile distilled water.
A portion of this stock suspension is diluted with the volume of sterile distilled water and the inoculum density of this trial dilution is compared by the addition of Antifungal standard. This suspension corresponds to an approximate bacterial density of 300 ml million per milliliter.
5.3 Preparation of assay plates. Melted SDA is poured into each sterile petri dish.The agar is distributed evenly in the plate and allowed to solidify. After the agar solidified the inoculums was transferred to the petri dish by a cotton swab. To spread the organism evenly in the petri dish multiple method of streaking was used.
5.4 Preparation of filter paper disc. Several pieces of ashless paper was cut into disc with the aid of a puncher. Then wrap with clean sheet of bond paper in lots of four. They are then sterilized in an autoclave together with the media for 15 minutes and dried in oven.
5.5 Microbiological Assay Method. Dip forceps in methanol, drain excess solvent, flame and allow to cool. Pick the sterile filter paper discs from the solution of alcohol (control), the extract and/ or the final product and the standard antifungal. Sterilize the forceps every time you pick the discs from each solution. Drain off excess solution by letting the disc touch the lip of the container. Gently press down the discs with the tip of the flamed forceps to ensure contact with the agar. Follow the pattern on the trace paper. Indicate the starting point on the plate. Allow three readings for alcohol, radish root extract and final product and standard antifungal. Incubate the plates at 37ºC for 24 hours. After incubation measure the zone of inhibition in mm. using vernier caliper. Get the average of the three measurements and record the results.
5.6 Ash determination - The ___ g of dried Radish roots were placed in tared porcelain casserole. Then it was heated until it was free of carbon and placed in a desiccators and the weight of the ash and% total ash was computed 5.7 Percentage Yield Determination The extract obtained from 80% ethyl alcohol was weighed and
measured for the determination of the percentage yield6. Physical and Chemical Methods of Analysis: 6.1 Physical Test 6.1.1 Organoleptic Test. By observation the odor, color, appearance, taste and the
physical state of the tannin was determined.
6.1.2 Solubility test About ___ g of the tannin was dissolved in 3ml of alcohol,
water, ether, chloroform, benzene and glycerin to determine its solubility.
6.2 Chemical Test About ____ g of the tannin extract was dissolved in l2 ml of
water and divided in four test tubes and treated with 1 ml of Ferric chloride T.S., Lead acetate T.S. ,Gelatin T.S., and Copper sulfate T.S.

4. Partial Purification
The alcohol filtrate is then treated with 1 ml of Sodium hydroxide T.S., and 1 ml of Calcium chloride T.S. The researcher repeated filtration and again, obtained filtrate and residue. The filtrate is now treated with Lead acetate T.S. and proceeded to filtration, this time, the filtrate was discarded and the residue was first added with hot water and then Hydrogen sulfide. Again, filtration was done until it turned to crystals. The crystals obtained are now the tannins.
