ozone (O3) [16].
Free radicals are also generated through cigarette smoke, automobile exhaust,
radiation, pesticides and air pollution etc [17].
Free radicals play a crucial role in normal aging and
neurodegenerative disorders [18].
Free radicals damage the cell membranes, proteins, fats and cause
heavy damage to the genetic material in the cell, this oxidative damage increase with age. Damaged
protein and enzymes can result in premature wrinkling, aging and even cancerous growths on the
damaged skin. [19],
Natural oxidants namely phenols in medicinal and dietary plants can prevent the
Oxidative damage caused by free radicals. Plants produce a variety of antioxidants Compounds to
control the oxidative stress caused by sunbeam and oxygen, so they represent a source of
compounds with antioxidant activity.
GEOGRAPHICAL AREAS:
The Achyranthes splendens are invasive part of:

ANTIOXIDANT ACTIVITY:
Oxidation is essential to many living organisms for the production of energy for Biological
process. However, oxygen centered free radicals and other reactive oxygen species (ROS), which
are continuously, produced in vivo, result in cell death and tissue damage. Antioxidants, free radical
scavengers prevent pathological conditions of human body namely ischemia, anemia, asthma,
arthritis inflammation, neuron degeneration, ageing process [20].
Some natural antioxidants are
ginger Root, gingko leaf, grape skin extract, guar gum seed, kudzu root, rosemary leaf, turmeric
root etc. Many synthetic antioxidants such as butylated hydroxyl anisole (BHA) and butylated
hydroxyl toluene (BHT) are very effective and are used for industrial process but they possess
potential health risk and toxic properties to human health. Literature survey revealed that chemical
constituents like flavanoids, triterpenoids, polyphenolic compounds and steroids are responsible for

plant in the pigweed family, Amarantheacea, Its natural habitatare dry forest, low shrublands,
and sandy shores. It is threatened by habitat loss [29].
A. splendens are following species:
Achyranthes aspera: which is commonly known as Latjeera (Hindi) & Rough Chaff tree (English).
It is the erect, annual or perennial herb, 1-2m in height, often with a woody base, commonly found
as a weed of waysides, on roadsides [30, 31, and 32].
A.aspera contains a triterpenoids saponin which
possesses oleanolic acid as the aglycon, an insect moulting hormone, and long chain alcohols,
which are also found in the A. aspera[33].
This plant is used for the liver complaints, rheumatoid
arthritis, scabies and other skin diseases. It also possesses tranquillizer properties [34, 35].
Achyranthes atollensis:It belongs to to the family Amarantheous. It is a natural habitat was sandy
shores. It was become extinct due to habitats (residential, commercial and military) and it was last
seen in 1964 [36].
Achyranthes arborescence: It is the commonly called a Chaff. Chaff Tree is a branched soft-
wooded tree growing to 9m tall. The leaves are like yellow-green to dark green, elliptic to slightly
lance-shaped, 5–8 cm long and 2–3.5 cm broad. The flowers are like white or pale yellow, with a
pale amber colour, and 20–90 flowers per inflorescence [37].
The flowers are enclosed by shining
pink colour, sharp-pointed bracts [38].
Achyranthes bidentata: English name: ox knee) [39]
is a species of flowering plant in the amaranth
family, Amarantheceae. It was found in India, Nepal, China, and Japan. Anti-inflammatory activity
is involved. In Nepal, root juice is used for toothache. Its seeds have been used for substitute for
cereal grains in famine years [40].
In Mizoram, the plant is used externally in the treatment of leech
bites, India and a decoction as a diuretic [41].
Achyranthes bidentata is used in Traditional Chinese
medicines. It inhibits collagen-induced arthritis and acute oedema. Most significantly, two novel
triterpene glycosides separated from the plant have been shown to be 1,000 times more potent. An
important blood group antigen that inhibits excess recruitment of neutrophils to injured tissues. This
property has made it useful for treating arthritis; when too many white blood cells are recruited to
an injured joint the neutrophils attack and destroy healthy tissues, leading to conditions such as
septic shock and rheumatoid arthritis [42].
Achyranthes mutica:It is also known as Blunt chaff flower is a species of Amarantheceae family. It
is endemic shrubs. Natural habitat is dry forest and subtropical or tropical dry shrubland. It is also

4. Wagner’s reagent test: Wagner’s reagent (solution of iodine in KI) was added to the extract,
reddish brown precipitates confirm the presence of alkaloids.
Test for sterols
1. Moleschott’s test: A few mg of the extract was heated with 1mL mixture of sulphuric acid
and water (5:1) red violet color confirms the presence of sterols.
2. Hess’s test: A few mg of the extract was dissolved in 1mL of chloroform and equal volume
of sulphuric acid, a blood red color confirms the presence of sterols.
Test for flavanoids
1. Aqueous sodium hydroxide test: Aqueous sodium hydroxide was added to the extract, a red
or purple color confirms the presence of flavanoids.
2. Concentrated nitric acid test: Concentrated nitric acid was added to the extract, crimson or
magenta color confirms the presence of flavanoids.
Test for tannins
Ferric chloride test: A few mg of the extract was dissolved in 2ml of distilled water and filtered. To
the filtrate ferric chloride solution was added. A bluish green/brownish green color confirms the
presence of tannins.
Test for carbohydrates
Molish test: A few mg of the extract was taken in 50% v/w ethanol. Two drops of 20% solution of
β-naphtha in ethanol was added and about 1mL of concentrated sulphuric acid was allowed to flow
down the sides of the test tube. A red or violet colored ring at the junction of two layers confirms
the presence of carbohydrates.
Test for anthraquinone glycosides
Brontrager’s test: A small amount of the extract was mixed in ether and after filtration aqueous
ammonia or caustic soda was added. Appearance of pink, red or violet color in aqueous layer after
shaking, confirms the presence of the anthraquinone glycoside.
Hydrogen peroxide (H2O2) free radical scavenging method:
Hydrogen peroxide (H2O2) free radical activity was determined according to the particular method
[47].The methanol fruit extract of Achyranthes splendens (MEAS) solution (1.0 ml in various
concentrations (100-200 μg mL-1
) was mixed with 2.4 ml of 0.1 M phosphate buffer (pH 7.4), and
then 0.6 ml of a 43 mm solution of H2O2 in the same buffer were added. After 10 min the
absorbance values of the reaction mixtures were recorded against a blank solution containing
phosphate buffer without H2O2 at 230 nm using a spectrophotometer. For each concentration, a
separate blank sample was used for background subtraction. Ascorbic acid was used as a standard
