TOXICITY OF EUGENOL
Eugenol is hepatotouix, meaning it may cause damage to the liver.
Overdose is possible, causing a wide range of symptoms from blood in the
patient’s urine to convulsions, diarrhea, nausea, unconsciousness,
dizziness or rapid heartbeat. According to a published 1993 report, a 2
year old boy nearly died after taking between 5 and 10ml eugenol is
subject to restrictions on its use in perfumery as some people may
become sensitized to it, however, the degree to which eugenol can cause
an allergic reaction in humans is disputed.
ALLERGY OF EUGENOL
Eugenol
is a component of Balsam of Peru to which some people are allergic.
When eugenol is used in dental preparations such as surgical pastes,
dental packing, and dental cement, it may cause contact stomatitis and
allergic cheilitis. The allergy can be discovered via patch test.
1.7.9 Terpenes
Terpene,
any of a class of hydrocarbons occurring widely in plants and animals
and empirically regarded as built up from isoprene a hydrocarbon
consisting of five carbon atoms, (C5 H8). The term is often extended to
the terpeniods, which are oxygenated derivatives of these
hydrocarbons.COCONUT WATER
Biological formation of the terpenes
occurs by the combination of two molecules of acetic acid to give
mevalonic acid (C6 H12 04) and conversion of the latter to isopentenyl
pyrophosphate, which contains the five carbon isoprene skeleton.
Further transformation of the isopentenyl compound yield the true
terpenes and the terpenoids.COCONUT WATER
The true terpenes are
usually grouped according to the number of isoprene (C5 H8) units in the
molecule: monoterpenes (C10 H16) contains two such units;
sesquisterpenes (C15 H24), three; diterpenes (C20 H32), four;
triterpenes (C30 H48), six; and tetraterpenes (C40 H64), eight. Rubber
and gutta-percha are polyterpenes in which 1,000-5,000 isoprene units
are joined in a long chain. Monoterpenes, sesquiterpenes, and diterpenes
are abundant in essential oils of plants: turpentine containe contains
several monoterpenes. Vitamin A is another important diterpene. The
triterpene squalene obtainable from shark-liver oil, may be converted
to cholesterol and many other steroids. The carotenoid pigments are the
best known tetraterpenes.COCONUT WATER
1.10 AIM
The aim of this work is to identify the phytochemicals present in cocos nucifera water extract.
1.11 Specific Objective
The specific objectives are to carry out phytochemical analysis on coconut water and also:
Collecting drying and pulverisationof coconut water.
Extraction of coconut water using distilled water by maceration method.
Determination of phytochemicals present in extract of the plant.

ABSRACT - [ Total Page(s): 1 ]Medicinal plants are the local heritage with global importance plants and plant based medicaments are the basis of many of the modern pharmaceuticals we use today for our various ailments. The research investigated the photochemical screening of coconut water. Coconut water was obtained fresh from coconut fruit and photochemical analysis was carried out according to standard procedures. The preliminary phytochemical analysis showed the presence of alkaloids, flavonoids, phenolics, steroids and t ... Continue reading---
