Specification

Some disorders in which free radicals implicated are Alzheimer's disease, arthritis, hemorrhoids, Parkinsonism, rheumatism, heart attack, AIDS, cataract, stroke, cancer and many degenerative diseases including aging. The oxidant/free radicals are species with very short half-life, high reactivity and damaging activity towards macromolecules like protein, DNA and lipid. These species may be either oxygen derived ROS (Reactive oxygen species) or nitrogen derived RNS (reactive nitrogen species). The oxygen derived species include O2" (Superoxide), H02 (Hydroperoxyl), ROO (Peroxyl), RO (Alkoxyl) as free radicals whereas H2O2 (Hydrogen Peroxide), HOC1 (Hypochlorous acid), O3 (Ozone) and O2 (Single oxygen) as non-radical. Similarly, nitrogen derived oxidant species are mainly NO (Nitric oxide), ONOO (Peroxy nitrite), N02 (Nitrogen dioxide) and N2O3 (Dinitrogen trioxide). The exogenous sources of ROS include electromagnetic radiation, cosmic radiation, cigarette smoke, car exhaust, UV light, ozone and low wave length electromagnetic radiation. Similarly, the endogenous sources of ROS are mitochondria electron transport chain, respiratory burst by phagocytes, β-oxidation of fat in peroxisome, auto-oxidation of amino acid, catecholamine's, hemoglobin and ischemia injury. Out of reactive nitrogen species (RNS), nitric oxide is the most important nitrogen derived physiological free radical. It was once considered as a mere toxic pollutant. Later studies reported NO to relax smooth muscles and involved either in the causation or recovery of several diseases, when overall generation of ROS and RNS exceeds the total antioxidants activity in the body, the resulting condition is called oxidative stress.
Antioxidants are the molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged. These are the substances that, when present at low concentrations compared to those of the oxidizable substrate, significantly delays, or inhibits, oxidation of that substrate. Some antioxidants are proteins and enzymes, while others are small molecules. From the viewpoint of mechanistic functions, the antioxidants may be classified into three types; preventing antioxidants, scavenging antioxidants and repair de novo antioxidants. Antioxidants (also known as free radical scavengers) function

by offering easy electron target for free radicals. In absorbing a free radical, antioxidant "trap" (de-energize or stabilize) the lone free radical electron and make it stable enough to be transported to an enzyme which combines two stabilizes free radicals together to neutralize.
Albizia lebbeck is a deciduous Tree with an open, large, spreading crown; it usually reaches a height of 15 - 20 meters, with exceptional specimens growing up to 30 meters. The straight, cylindrical bole can be 50 - 100cm in diameter, with exceptional specimens. In India plantation-grown siris yields a high quality hardwood that is traded in Europe as 'Indian walnut' or 'koko'. The tree has been widely planted in agro-forestry schemes in the drier parts of the Tropics. Plants are used to provide shade for coffee and cocoa plantations as well as to provide a valuable timber and fuel. It is a popular amenity tree throughout the dry tropics because of its shady spreading habit, although the copious litter produced beneath it is often regarded as a disadvantage. Synonyms:

A. lebbeck is indigenous to the Indian subcontinent and to those areas of South-East Asia with a marked dry season, such as northeastern Thailand, parts of Malaysia and in the eastern islands of Indonesia. This plant is common in Andaman & Nicobar Island, Andhra Pradesh Assam, Kerala, Madhya Pradesh, Maharastra, Meghalaya, Odisha, Rajasthan, Uttar Pradesh. Traditional uses
Albizia lebbeck has many medicinal properties like Antiseptic, antibacterial, anti¬allergic, antidermatosis, antidysenteric etc. Used in the treatment of Bronchitis, piles, hemicranias, cough, tropical pulmonary eosinophilia, asthma etc. Albizia lebbeck is used as an astringent, to treat boils, cough, to treat the eye, flu, gingivitis, lung problems, pectoral problems, to treat abdominal tumors and it is

also used as a tonic. The bark is used medicinally to treat inflammation. Albizia lebbeck is also psychoactive. The wood of Albizia lebbeck is suitable for construction, furniture and veneer. The flower emollient is used as a poultice to be applied to boils. The bark and seed astringent are used against diarrhea, dysentery and hemorrhoids. The seed yields oil used as a cure for leprosy. Albizia lebbeck used in Indian traditional medicine, particularly for asthma and allergic disorders.

SILYMARIN is a C25 containing flavonoid mixture, extracted from the Silybum marianum (milk thistle) plant. Today's standardized (according to its silibinin, often called silybin, content) SM extract contains approximately 65% to 80% flavonolignans (silybin A and silybin B, isosilybin A, isosilybin B, silychristin and silydianin), with small amounts of flavonoids, and approximately 20% to 35% of fatty acids and polyphenols compounds possessing a range of metabolic regulatory effects. Silybin was discovered as the first member of a new family of natural compounds called flavonolignans in 1959 and it is known as the predominant and primary active ingredient in SM. That is why compounds containing milk thistle ingredients showing silybin content and silybin antioxidant, as well as other activities in various model systems, are used to explain the biological activity of SM. In particular, SM has been the gold standard drug to treat liver disorders of different etiologies and milk thistle extracts have been used as traditional herbal remedies ("liver tonics") for almost 2000 years. Therefore, SM is most well known for its antioxidant and chemoprotective effects on the liver and it is often prescribed and self-prescribed as a complementary and alternative hepatoprotective medicine [Ref Antioxidants 2015, 4, 204-247; doi:10.3390/antiox4010204].

The present disclosure is further described in light of the following experiments which are set forth for illustration purpose only and not to be construed for limiting the scope of the disclosure. The following experiments can be scaled up to industrial/commercial scale and the results obtained can be extrapolated to industrial scale.
EXAMPLES
EXAMPLE 1: Antioxidant activity DPPH (2,2-diphenyl-l-picrylhydrazyl)
Assay
The method is based on the scavenging of DPPH by antioxidants, which upon a reduction reaction decolorizes the DPPH methanol solution. The assay measures the reducing ability of antioxidants toward the DPPH radical.
200 l of the test sample solution was added to 4ml of 100 mM methanolic
DPPH. The sample tubes were wrapped with aluminum foil and kept in dark for
30 min at room temperature and the absorbance was measured at 517nm using
UV-Vis spectrophotometer with solvent and DPPH as blank. Ascorbic acid (100
mg/ml) was used as reference. The percentage inhibition of DPPH activity was
estimated using the formula:
Acontrol — Asample
Percent inhibition of DPPH = X 100
Acontrol
where Acontrol is the absorbance of DPPH in methanol without an antioxidant and Asample is the absorbance of DPPH in the presence of an antioxidant
The antioxidant activity data of the selected test compounds are listed in Table 1. The DPPH radical was scavenged by antioxidants via donation of hydrogen resulting in the formation of DPPH. The colour of the DPPH changed from purple to yellow after reduction, which was quantified by the decline of absorbance at a wavelength of 517 nm. Among the tested compounds, the combination showed
