![Page 2: 1st project](https://reader033.vdocuments.net/reader033/viewer/2022061219/5483baf9b4af9f80568b45dc/html5/thumbnails/2.jpg)
IT is genarally found in farms as a weed means there is no use of this climber.

SEED
The Seeds are rich in fatty acids such as myristic, palmitic, stearic, oleic, linoleic and linolenic acids.
Citrullus oil has a good potential use as cooking oil.
The Investigation revealed that seed extract have an insulin tropic effect which show anti diabetic activities.

FRUIT AND FRUIT PULP
The fruit is pungent, a cooling purgative, antihelmetic, antipyretic and carminative.
The fruit pulp is purgative, diuretic and is used against gonorrhea.
A fruit of Citrullus colocynthis is traditionally used for the treatment of diabetes, microbial diseases, ulcer, inflammation, jaundice and urinary diseases in Asian and African countries.

LEAVES The leaves exhibit anti-inflammatory
activity and are diuretic.

INSECTICIDAL PROPERTIES
Cucurbitacin E Glycoside Isolated from Citrullus colocynthis show insecticidal effect against Aphis craccivora.
Aphis craccivora can spread viruses. After NMR and IR spectrophotometer analysis
we confirmed that the compound which isolated from Citrullus colocynthis and has insecticidal effect against Aphis craccivora was 2-O-β-D-glucopyranosylcucurbitacin E. (Torkey.H.M and Abou-Yousef,H.M.,2009)

ANTIMICROBIAL ACTIVITY
METHODS - In this procedure we can use either 1st
or 2nd methods to examine antimicrobial activity
AGAR- WELL DIFFUSION METHOD. DISC DIFFUSION METHOD.
![Page 10: 1st project](https://reader033.vdocuments.net/reader033/viewer/2022061219/5483baf9b4af9f80568b45dc/html5/thumbnails/10.jpg)
AGAR- WELL DIFFUSION METHOD
Petriplates -- 20ml medium -- 24hr culture of bacterial strains.
Wells -- 20 µl of the plant extracts added.
Incubated at 37°C for 24 hours. Measure diameter of obtained
antimicrobial activity.

DISC DIFFUSION METHOD
Prepare agar plates Inoculation of test microorganisms with
spread plate method Filter paper discs -- 6mm in diameter --
soaked with 15µl of the plant extract Place (and press) in agar plate but no closer
than 24 mm from each other, center to center
Incubate -- 37ºC -- 16 to 18 hours. Measure diameter of obtained antimicrobial
activity.

PROCEDURE
Collection and identification of plant material
Collect fresh climbing plant. Confermed by botany teacher. Expose to air till it completely dried. Preparation of extract Leaf(Citrullus colocynthis) – Dried –
Powdered – extract by soxhlate (aqueous) – concentrated by Rota evaporator – Extract prepared.
![Page 15: 1st project](https://reader033.vdocuments.net/reader033/viewer/2022061219/5483baf9b4af9f80568b45dc/html5/thumbnails/15.jpg)
Leaf(Citrullus colocynthis) – Dried – Powdered – extract by socslate (Ethanol) – concentrated by rota evaporator – Extract pripared.
Seed = Dried–powdered- extract by socslate (aqueous) – concentrated by rota evaporator – Extract pripared.
Root = Dried–powdered- extract by socslate (aqueous) – concentrated by rota evaporator – Extract pripared.

Material - 15 Petri plates – Conical flask containing
nutrient agar – 15 suspension tubes containing saline were sterilized for further use.
Bacterial Strains – E.coli Bacillus megaterium Bacillus cereus Pseudomonas aeruginosa Streptococcus mutans
![Page 18: 1st project](https://reader033.vdocuments.net/reader033/viewer/2022061219/5483baf9b4af9f80568b45dc/html5/thumbnails/18.jpg)
Actual Method – Pour agar (20ml) in each Petri plate Bacterial strains were poured and
spread Make well (about 6mm) in Petri plate at
center Fill the well with respective extract. Finally incubate the plates for 24 - 48
hrs

RESULT –
The bitter water melon (Citrullus colocynthis) has antimicrobial (bacteria) activity.
CONCLUSION - There is a great promise for development of
novel drugs from the plant Citrullus colocynthis for dreadful human diseases.
They affects the growth of insect and degrade them so it can use in several insecticide, pesticide etc.

They have some medicinal properties i.e antidiabetic activity,
They shows the antibacterial activity which helps to inhibit the growth of bacteria which affects the plants.
