Annona squamosa is most widely distributed in tropical and subtropical region native to tropical America comes under the Annonaceae family. It is a widely used tree having edible fruits called as custard apple which is eatable. Annona squamosa plant also contains 35-42 mg/100 g of vitamin C and significant value of nutrient like thiamine, amino acid, riboflavin, niacin, calcium, potassium and dietary fibers. It also contains the phytoconstituents like diterpenes, alkaloids, cyclopeptides and annonaceous acetogenins proved by phytochemistry investigations. The plant Annona squamosa show a number of pharmacological activities like insecticidal, anticancer, hypoglycemic, antioxidant, antimalarial, analgesic and wound healing activity. The vermicidal effect of leaves is responsible for the treatment of tumors, wounds and other skin infections. A number of alkaloids were isolated from the leaves of plant. Most of them belong to aporphine group of alkaloids. Among all the phytoconstituents an alkaloid Annonaine, plays a vital role for its biological activity. The present review represents the phytochemical constituents, biological action, traditional as well as medicinal uses of Annona squamosa. Sugar apple might be the better explored plant part used in treatment of many disorders and the present critical study will hopefully provide a disease free and healthy life to the human society.

The chemical diversity within the natural products is an immensely rich source of new pharmaceuticals, cosmetics and other economically important chemicals. Presently, numerous pure compounds are being isolated from plant sources having very promising therapeutic profiles. Now, the synthetic drugs are gradually sidelined by phytomedicines due to their adverse effects and the inability to provide complete cure in certain diseases and disorders in a cost effective manner. The present study was done to evaluate the therapeutic potential of the plant leaves of Abies webbiana. The anti-inflammatory activity of benzene extract of Abies webbiena leaves was investigated by carrageenan-induced rat hind paw edema method using mercury displacement technique with the help of travelling microscope. The benzene extract showed significant activity in a dose dependent manner as compared with standard drug diclofenac sodium. The extract containing tannins which have significant role of free radical scavenging may have the ability to produce anti-inflammatory activity.

Many efforts have been made through publication of traditional studies on plants to increase the interest and improve on natural remedy since past few years. Eleusine indica is a diploid species of genus Eleusine belongs to family Poaceae. More than 20 diseases are traditionally treated by this plant around the different tropical and subtropical region of world. Phytochemically many inorganic and organic active constituents have been isolated from the plant. Many secondary metabolites has been isolated and identified such as vitexin, isovitexin, orientin, isoorientin, lutein, β-sitosterol, stigmasterol and derivatives of sterol glucosides belongs to categories of flavonoids, caretenoid and sterols. Plant possesses active constituents attributes several pharmacological actions like antimicrobial, anti-inflammatory, diuretic, anticonvulsant, antiobesity, anticancer, antihypertensive, antioxidant, hepatoprotective, etc. Further investigations are essential to fulfil many research gaps which were identified and still many bioactive constituents have to be discover in respect to traditional and pharmacological use.
