*ABSTRACT*

-
Chrysophyllum cainito is a tropical tree of the family Sapotaceae, native to the lowlands of Central America and the West Indies. It grows rapidly and reaches 20 m in height.It has numerous common names including cainito, caimito, star apple, golden leaf tree, abiaba, pomme de lait, estrella, and aguay. It is also known by the synonym Achras caimito.

The leaves are evergreen, alternate, simple oval, entire, 5-15 cm long; the underside shines with a golden color when seen from a distance. The tiny flowers are purplish white and have a sweet fragrant smell. The tree is also hermaphroditic (self-fertile).

It has round, purple-skinned fruit that is often green around the calyx, with a star pattern in the pulp. Sometimes there is a greenish-white variety of the fruit. The skin is rich in latex, and both it and the rind are not edible. The flattened seeds are light brown and hard. It bears fruit year around after it reaches about seven years of age.

The fruits are delicious as a fresh dessert fruit; it is sweet and best served chilled. The flattened seeds are light brown and hard. Infusions of the leaves have been used against diabetes and articular rheumatism. The bark is considered a tonic and stimulant, and a bark decoction is used as an antitussive.

STATEMENT OF THE PROBLEM*

-
Does the extract of a star apple(chrysophyllum cainito)leaves can be made as paste?

*HYPOTHESIS*

-
If I use the extract of a star apple leaves as paste,it can be useful to our community cause contain an alkaloid,resin,resinic acid and a bitter substances that can be use as paste.

*SIGNIFICANCE OF THE STUDY*

-
It makes my study important cause it can be used in many ways, such as pasting works,decorating,painting & other things.Also its not expensive but it can give us low price.Like other paste or glue, it also useful in our economic......

*
SCOPE AND LIMITATIONS*

-
I want to include in my study the other parts of a star apple that has extract so that I will determine which part have more extract than the leaves.And also I will statistical test used to determine the possible limitations of the finding.

>STAR APPLE( CHRYSOPHYLLUM CAINITO)
-
a tropical American tree of the Sapodilla family.

=>CLOSE CONTAINER

-a receptacle, designed to contain goods or substance; a standardized receptacle used to transport commodities.

*RESULT AND DISCUSSION*

-
the researcher observe that the extract of a star apple leaves can be use as paste, it is also useful in our community because it contains alkaloid,resin,resinic acid and a bitter substances that can be use as paste. I use the paste from the extract of star apple leaves in paper ,illustration boards and many others.

*CONCLUSION*

-
There fore i conclude that the extract of Star Apple leaves can be used as paste and it is environment friendly.Like other paste it is also very effective.
