It produces about 93\% water; hence name "water" melon \hyperref[b0]{[1]}. C. lanatus is a prostrate animal plant with several herbaceous, firm and stout stems. The leaves are herbaceous but rigid, becoming rough on both sides. The leaf stalks are somewhat having and up to 150 mm long. The tendrils are rather robust and usually divided in the upper part. They are monoecious with the flower stalk up to 4mm long and to 20mm in diameter; the fruit still is up to 50mm long \hyperref[b1]{[2]}.\par C. lanatus seeds are increasingly used for their oil in semi-arid regions and also the use of the oil in the cosmetic and pharmaceutical industry is increasing. There are also prospects for use of the seeds in the improvement of infant nutrition in review of their high protein and fat content \hyperref[b2]{[3]}. In Chinese traditional medicine, watermelon rind is extensively applied to clear away heat to eliminate toxic substances and its extracts are available in powdered form \hyperref[b3]{[4]}. In Nigeria, watermelon rind is fermented, blended and consumed as juice. High antioxidant activities have been reported on food products in microbial fermentation \hyperref[b4]{[5]}.\par One generous slice of watermelon (about 1/16th of a melon) contains large amounts of vitamin C and Beta-carotene which may help against various forms of cancer due to their antioxidant properties. Watermelon is also high in potassium which helps regulate heart function and normalize blood pressure. It is a good source of fiber also which helps maintain bowed regularity and works to prevent colon and renal cancer \hyperref[b4]{[5]}. Emulsion obtained from the seed water extract of watermelon is used to cure catarrhal infections, disorders of the bowel, urinary passage and fever \hyperref[b5]{[6]}. The plant contains large amount of betacarotene and it is a natural source of lycopene. It is also rich in citrulline, an effective precursor of L-arginine \hyperref[b5]{[6]}. Phenolic compounds are constituents of both edible and non-edible parts of the plant. The seeds are sources of protein, tannins and minerals \hyperref[b6]{[7]}.\par The antimicrobial compounds found in pants are of interest because antibiotic resistance is becoming a worldwide public health concern in terms of food borne illness and nosocomial infections \hyperref[b7]{[8]}. The plane kingdom has proven to be the most useful in the world's pharmaceuticals \hyperref[b8]{[9]}. The most important of these bioactive constituents of plants includes phenol, tannin, saponin, alkaloid, flavonoid, steroids, carotenoids, and cyanogenic glycosides \hyperref[b9]{[10]}. These phytochemicals constitute the antibiotic principals of plants \hyperref[b8]{[9]}. They are found to be distributed in plants \hyperref[b10]{[11]}. Leaves, roots, flowers, whole plants, seeds and stems have being examined in many research projects, few reports refers to seeds as sources for pharmaceutical \hyperref[b11]{[12]}. Chemical compounds including alkaloids, lectins and phenolic compounds such as lactones, tannins and flavonoids are present in seeds and seed coat \hyperref[b11]{[12]}, and they probably function in the protection of seeds from microbial degradation until conditions are favorable for germination \hyperref[b12]{[13]} \hyperref[b9]{[10]}.\par Many studies suggest that endogenous antioxidant or exogenous antioxidants supplied by diet can function as free radical scavengers and improve human health \hyperref[b13]{[14]} [15] \hyperref[b15]{[16]}. Thus consumption of a variety of plant foods including watermelon seeds may provide additional health benefits \hyperref[b16]{[17]}. Amongst all the amino acids which the body requires, there are some known as essential amino acids which the body cannot produce C. lanatus seeds supply some of these acids including tryptophan and glutamic acids.\par Effective health cannot be achieved in Africa, unless orthodox medicine is complemented with traditional medicine. At least, 80\% Africans depend on plant medicine for their healthcare \hyperref[b17]{[18]}. Fruits and vegetables have been recognized as natural sources of various bioactive compounds \hyperref[b18]{[19]} which could be attributed to their phyto-constituent such as flavonoids, fiber and phenolic compounds.\par One of such medicinal plant is Citrullus lanatus.\par Although several of its uses in traditional medicine have been documented, many of these claims are yet to be validated by scientific researchers. Therefore a review of some investigated phytochemical components and therapeutic activities of the plant are highlighted in this present study. each (with filter paper imbedded) then 60ml of hot water, cold water, ethanol and methanol were added respectively and allowed to settle for some time. The filtrate of the extracts was obtained by separation of the suspension in the filter paper. Ethanolic and methanolic extracts were allowed to evaporate and stored in an airtight conical flask. The hot and cold water extracts were then neatly separated and also stored. \section[{II.}]{II.} \section[{Materials and Methods}]{Materials and Methods} \section[{c) Phytochemical Analysis}]{c) Phytochemical Analysis}\par The phytochemical analysis was performed using universal laboratory techniques for qualitative determination \hyperref[b19]{[20]} \hyperref[b21]{[21]}. The phytochemical analyzed includes phenols, saponin, flavonoid, alkaloids, tannin and cyanogenic glycoside. i.\par Phenol Analysis 2g of the sample was emerged in 20ml of methanol, extracted by filtration through filter paper. 1ml of the filtrate was testes by adding 1ml of Folinconcalteon plus 1ml of 20\% NaCO3, the presence of dark blue color shows the presence of phenol.\par ii. \section[{Saponin Analysis}]{Saponin Analysis}\par About 20ml of water was added to 10.25g of the specimen in 100ml beaker and boiled gently on a hot water bath for 2 minutes. The mixture was filtered hot and allowed to cool and the filtrate used for frothing test. Frothing Test About 5ml of the filtrate was diluted with 20ml of water and shaken vigorously. A stable froth (foam) upon standing indicates the presence of saponins.\par iii. Flavonoid Analysis 10ml of ethylacetate was added to about 10g of the sample and heated in a water bath for 3 minutes. The mixture was cooled, filtered and the filtrate used for ammonium test. Ammonium Test About 5ml of filtrate was shaken with1ml of solute ammonia solution. The layers were allowed to separate and the yellow colour in the ammonical layer indicates the presences of flavonoids. iv. Tannin Analysis About 5g of the specimen was boiled with 40ml of water, filtered and used for the ferric chloride test.\par Ferric Chloride Test: About 3ml of the filtrate was added to few drops of ferric chloride solution. A greenish black precipitate indicates the presence of tannin. \section[{v. Cyanogenic Glycoside Analysis}]{v. Cyanogenic Glycoside Analysis}\par Fehling's Test: About 5ml of mixture of equal parts of Fehling's solution I and II were added to about 3ml of the filtrate and boiled for 5minutes. A more dense brick red precipitate indicates the presence of glycoside. The isolates were screened to confirm their identities. They were sub-cultured on nutrient agar and stored on slant before use \hyperref[b22]{[22]}. \section[{e) Sensitivity Test}]{e) Sensitivity Test}\par The antibacterial activity of the four (4) extracts of the C. lanatus seeds were tested using the Agar well diffusion techniques standardized inocula culture of the respective test organisms was spread evenly on the surface of nutrient agar plates. Wells of 6mm were aseptically punched on the agar using a sterile cork borer allowing at least 30mm between adjacent wells and the Petri dish. Different concentrations of the 4 different extracts (1000, 500, 125 and 62.5mg) of C. lanatus seeds were then introduced into the wells. Each extract was screened separately. The plates were incubated at 37 0 C for 24hours \hyperref[b23]{[23]}. Activity was determined by measuring the diameter of the zone of inhibition produced by the extracts against the test organisms.\par The different concentrations were used for determine the minimum inhibitory concentration using Mueller Hinton Agar. \section[{III.}]{III.} \section[{Results}]{Results}\par Table \hyperref[tab_0]{1} shows the phytochemical components of watermelon seed extracts. The presence of phenol, saponin, tannin, flavonoid and cyanogenic glycosides were observed. Amongst the observed phyto-components, only cyanogenic glycoside was not present in the ethanol extracts. \section[{Discussion}]{Discussion}\par The phytochemical analysis showed the presence of phenol, saponin, flavonoid, alkaloid and cyanogenic glycoside. The presence of these phytocomponents has been linked with the antibacterial activity of plants and plants that contain them in higher amount are considered to be superior in their antimicrobial activity \hyperref[b24]{[24]} [25] \hyperref[b21]{[21]}.\par The result of antibacterial activity of the extract against selected human pathogens indicated that the plant sample was active against a wide variety of human pathogenic bacteria. Ethanol extracts exhibited the highest inhibitory effect followed by methanol, hot water and cold water in that trend. This result agrees with the findings made by \hyperref[b26]{[26]} where ethanol extract proved active in inhibition of the tested organisms than other extraction solvents. The low inhibition effect shown by the aqueous extracts as compared to ethanol and methanol could be due to the fact that these phytocomponents are more soluble in ethanol and methanol than in water or that the hot water could have caused the denaturing of the active components.\par However, most of the Gram negative organism e.g. E. coli showed high susceptibility than most of the Gram positive. The higher susceptibility of the Gram negative bacteria is difficult to explain in the study considering the observation of [27] that the Gram negative bacteria appear to be more resistant to antimicrobial agents than the Gram positive bacteria. This resistance has been observed to reside in the complex cell wall and cell membrane structure. More so, more antibacterial activities were observed with high concentration of the extracts than at lower concentrations. Activity even at low concentration indicates high potency of the extract against the microorganism.\par V. \section[{Conclusion}]{Conclusion}\par These results gotten from the phytochemical analysis and antibacterial activity of the watermelon seed extracts supports the application of the extracts in ethno-medicine and will serve as a good source in pharmaceutical productions against some pathogenic microorganisms.
