The free radical scavenging activity of Thespesia populnea bark (TPBE) and leaves (TPLE) has been studied using the methanolic extracts. In vitro antioxidant potential of leaves and stem bark were evaluated in three different models viz superoxide radical scavenging activity, lipid peroxide radical scavenging activity and hydroxyl radical scavenging activity. The two methanolic extract were prepared with different concentration from a maximum of 400μg to minimum of 50μg. All extract have different level of antioxidant property. In comparison, the antioxidant scavenging activity in hydroxyl radical was higher, In super oxide radical was moderate and lesser in lipid peroxide radical. These observations confirm that methanolic extract of Thespesia populnea bark and leaf have different polyphenolic constituent and its importance in antioxidant activity.Keywords

It is well known and all the parts are used in traditional system of medicine. The plant has been used as astringent, antibacterial, hepatoprotective, haemostatic, anti-diarroheal and anti-inflammatory. The scientific parameter is necessary to identify the exact plant material and to find its quality and purity. The present study deals with various pharmacognostical examinations like organoleptic or macroscopical characters, microscopical or anatomical studies, physical evaluation and preliminary phytochemical screening of various successive extracts were carried out and the parameters were reported.

Tulsi has got the great medicinal value. Studies have also shown Tulsi to be effective for diabetes, by reducing blood glucose levels. The same study showed significant reduction in total cholesterol levels with Tulsi. Another study showed that Tulsi's beneficial effect on blood glucose levels is due to its antioxidant properties. The Rama Tulsi is the effective remedy for the severe acute Respiratory Syndrome. Juice of its leaves gives relief in cold, fever, bronchitis and cough. Tulsi oil is also used as the ear drop.

For over the centuries Tulsi (the queen of herbs) has been known for its remarkable healing properties. Modern scientific research offers impressive evidence that Tulsi reduces stress, enhances stamina, relieves inflammation, lowers cholesterol, eliminates toxins, protects against radiation, prevents gastric ulcers, lowers fevers, improves digestion and provides a rich supply of antioxidants and other nutrients. Tulsi is especially effective in supporting the heart, blood vessels, liver and lungs and also regulates blood pressure and blood sugar. Recent studies suggest that Tulsi may be a COX-2 inhibitor, like many modern painkillers, due to its high concentration of eugenol (1-hydroxy-2- methoxy-4-allylbenzene). Tulsi also shows some promise for protection from poisoning and cataracts. The oil extracted from the Karpoora Tulsi is mostly used in the herbal toiletry. Its oil is also used against the insects and bacteria. Tulsi can not only keep the dreaded Swine flu or H1N1 flu at bay but also help in fast recovery of an afflicted person, Ayurvedic practitioners claim.

Ginger is a perennial herb, with underground branching stems (rhizomes) which are swollen and tough. The leaves and rhizomes of ginger have a characteristic fragrance when cut or bruised. Rhizomes are dug out after the leafy parts are dried. Ginger, the underground stem, or rhizome, of the plant Zingiber officinale has been used as a medicine in Asian, Indian, and Arabic herbal traditions since ancient times. Ginger is considered an herbal remedy in many cultures. Over the years, it has been used to reduce inflammation, help with digestion, improve cardiovascular health and even historically to ward off diseases like the plague. The rhizome can be sliced, chopped, minced or served fresh but will always carry the trademark "heat" that has made it a medicinal mystery. Historically, people used ginger to fight disease and cure a fever since people would sweat when they would eat the ischolar_main. Although that helps, since it gets the metabolism racing and warms the body, we now realize that ginger offers additional medicinal benefits. Consumption of ginger helps with blood circulation and has antiinflammatory qualities that ease arthritis and other body aches and pains. It increases the body's production of saliva and other digestive fluids, which relieves an upset stomach and supports healthy digestion. Speeding up digestion helps clean the kidneys and bowels to remove toxins from the body. It also helps ease morning sickness, nausea and motion sickness. Ginger is said to improve digestion and has been known to pep up the appetite, promote saliva production, combat dyspepsia and relieve flatulent colic. It is also thought to be helpful for stomach cramps, alcoholic gastritis and hangover. The shogaol content in Ginger increases the activity of the digestive tract and is particularly helpful in digesting rich, fatty foods. Ginger has been used to cleanse the body of toxins through the skin by stimulating and increasing perspiration and has also been useful in breaking fevers. It is slightly diuretic and further cleanses the body by strengthening kidney function and increasing kidney filtration.
