1.7.5 Phonolics
Phenol
Test: When 0.5ml of fecl3 (W/V) solutions was added to 2ml of test
solutions, formation of an intense colour indicated the presence of
phenols.
1.7.6 Tannins
Ferric Chlodride Test: Small
quantity of extract was boiled in 20ml of water in a test tube and then
filtered. A few drop of 0.1% ferric chloride was added and observed for
brownish green or blue-black coloration which indicate the presence of
tannis.
1.7.7 Steriods
Salkowski Test: To 2ml of extract, add 2ml
chloroform and 2ml concentrated H2S054 and was shaken well chloroform
layer appeared red and acid layer showed greenish yellow fluorescence
indicated the presence of steriols.
Liberman-Burchard’s Test: Mix 2ml
extract with chloroform acid, 1-2ml acetic anhydride and 2 drops
concentrated H2S054 from the side of the test tube. First red, then blue
and finally green colour indicated the presence of sterols.COCONUT
WATER
Bioactive constituents which have been reported include
stigmastane type saponnins (vernoniosides) steroidal saponins,
sesquiterpene lactones vernomygdin, hydroxy vernolide), phenolics acids
lignans, xanthones, anthraquinanes, terpenese, coumarins and peptides
edoties). Nutrient composition of coconut water are vitamins, glucose,
potassium minerals, electrolytes, enzymes, amino acids, cytokine, and
phyto-hormones.
1.7.8 Eugenols
H0
Eugenol
is a phenypropene, on allyl chain-substituted guaiacol. Eugenol is a
member of the phenylpropaniods class of chemical compounds, it is a
colourless to pale yellow oily liquid extracted from certain essential
oils especially from clove oil, nutmeg, cinnamon, basil and bay leaf. It
is present in concentrations of 80-90% in clove bud oil and at 82-88%
in clove leaf oil.COCONUT WATER
Modern Uses of Eugenol
Eugenol is
used in perfumeries, flavorings, essential oils and in medicine as a
local antiseptic and anesthetic. Eugenol can be combine with zinc oxide
to form a materials known as zinc oxide engonel which has restorative
and prosthodontic applications in dentistry for example, zinc oxide
eugenol is used for root canal sealing it can be used to reduce the
presence of listeria monocytogenes and lactobacillus sakei in food. Thet
are also used in manufacturing stabilizer and antioxidants for plastics
and rubbers. Attempts have been made to develop eugenol derivatives for
intravenous injection, such as propanidid and G.29.505. the latter
produced unacceptable side effects around the site of injection in many
patients it is one of many compound that is attractive to makes of
various species of orchid bees, which apparently gather the chemical to
synthesize pheromones, it is commonly used as bait to attract and
collect these bees for study. It also attract male cucumber beetle it is
recently discovered that eugenol and isoeugenol, flora volatile scent
compound, are catalyzed by single type of enzyme in gymnadenia species
and gene encoding for this enzyme is first functionally characterized
gene in this species so far.
It is commonly used in wisdom tooth
extraction surgeries complicated by dry socket. Clove oil is growing in
popularity as an anesthetic for use on aquarium fish as well as a wild
fish when sampled for research and management purposes. Where readily
available, it presents a humane method to euthanize sick and diseased
fish either by direct over dose or to induce sleep before and overdose
of ethanol; it is used in some mousetraps and skills certain human colon
cancer cell lines in vitro and in vivo. Eugenol may have potential
therapeutic effects against diseases characterized by excessive
osterclast activity.COCONUT WATER

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---
