To determine the biochemical compounds, carbohydrates, proteins, total fat and crude fiber, free amino
elements, thiamine, niacin, riboflavin, vitamin-E, vitamin- C, and heavy metals lead (Pb), copper (Cu),
cadmium (Cd), molybdenum (Mo), aluminium (Al), and zinc (Zn) in a two tropical medicinal plants
Syzygium jambos and Syzygium travancoricum. UV spectrophotometer, Atomic absorption
spectrophotometer these instruments are used to determine the elements. These elements contents in the
medicinal plants of Syzygium species are at different levels. Plants are rich in some essential elements,
which is very useful in human beings and very least in heavy metals.

Nutraceuticals are "naturally derived bioactive compounds that are found in foods, dietary
supplements and herbal products, and have health promoting, disease preventing and
medicinal properties." Plant derived Nutraceuticals/functional foods have received
considerable attention because of their presumed safety and potential nutritional and
about more than 2000 species and has a vast geographical area with high potential abilities for
Ayurveda, Unani, Siddha traditional medicines but only very few have been studied
chemically and pharmacologically for their potential medicinal value. Starting from the ancient
time, medicinal plants have been used to prevent and treat various health problems. Plants are
still an independent source of medication in the contemporary health care delivery system.
Their role is twofold in the development of medicines and served as a natural blue print for the
development of new drugs.
belong to the family Myrtaceae, S. jambos is commonly known as rose apple
, which is
used for a variety of ailments and is known for its antipyretic and anti-inflammatory
properties. All parts of the plant are reported to have medicinal value. The leaf decoction is
used as a diuretic, a remedy for sore eyes and for rheumatism. Seeds and bark is administrated
to relieve asthma, bronchitis diabetes dysentery, diarrhea and catarrh
is longitudinally fissured and greyish brown in colour. Leaves are simple, petiolate and large
in size. Flowers are small, bisexual and white in colour. Fruit is berry type of deep purple
colour containing single seed. S. travancoricum is known for its medicinal value. Traditionally
this plant species has been used for curing diabetes and arthritis by local people. The species is

One main strategy in the bioactivity-guided isolation, in
the isolation of the work described in this dissertation is an
attempt to isolate and characterize the nutritional profile of
Syzygium sp. (Fam. Myrtaceae).
2. Materials and Methods
2. Plant materials
Leaves of S. jambos and S. travancoricum were collected
from Nadugani village Gudalur, The Nilgiris, India. The plant
materials were properly authenticated by Botanical Survey of
India, TNAU, Coimbatore, Tamil Nadu. The collected plant
species, under shade dried and grounded into powdered in 1
mm particle size using a lab mill.

carbonate. It was then centrifuged and the supernatant was
collected for analysis. The analysis was carried out following

The data on the nutritional parameters of the leaf samples

All values are mean of triplicate determinations expressed on dry
high levels of nutritional values than the S. travancoricum
leaves. A poor diet may have an injurious impact on health,
causing various alments.
The data on mineral composition of leaf samples are
presented in table-2. In both the plant samples, the S.
travancoricum has registered highest mineral content of the
composition. Minerals an increase in skeletal mass and blood
volume, The body needs calcium, phosphorus, and iron.
Calcium intake needs to be increased to prevent osteoporosis
in later life. It is present in milk and milk products, lack of
iron in the diet result in anemia.
Vitamins are recognized as essential nutriens, necessary in the
diet for good health. (Viamin D is the exception it can be
synthesized in the skin, in the presence of UVB radiation.)
Vitamin deficiencies may result in disease conditions,
including goiter, scurvy, osteoporosis, impaired immune
system, disorders of cell metabolism, certain forms of cancer,
symptoms of premature aging and poor psychological health
(including eating disorders), among many others (Shils,
Present study, among this samples, S. travancoricum has
registered the highest levels of vitamin content, (Table-3).

were present in the sample in low detectable level.
Syzygium species are more medicinally important. Hence
determination of elements in these plants is also important.
This is the first report on nutritional profile, minerals,
vitamins amd trace elements in Syzygium travancorium
leaves. More advanced pharmacological and clinical studies
would be required to investigate in vivo mechanism of
nutraceuticals effects of this important tropical medicinal
