Anti- inflammatory

Garcinia pedunculata is a medicinal plant commonly known as Amlavetasa, belonging to the family Clusiaceae. The fruit of Garcinia pedunculata were used in the diet as a spice. It has been used as folk remedy in different ailments such as chronic catarrh, asthma, cough, bronchitis, cardiotonicand fever. The present study has been carried out to evaluate the anti inflammatory activity of aqueous extract of fruits of Garcinea pedunculata by carrageenan induced paw edema method. Eighteen healthy wistar albino rats were divided into three different groups of six rats each. Group I administered with normal tap water (5ml/kg) served as normal control. Group II administered with Ibuprofen 100mg/kg served as reference standard and group III administered with aqueous extract of fruits of Garcinea pedunculata(400mg/kg). In Acute oral toxicity study there was no mortality in any dose up to 2000mg/kg. The aqueous extract of fruits of Garcinea pedunculata has shown significant anti inflammatory activity by significantly decrease in the paw volume recorded at three different time interval compared with control group (**p< 0.01). It can be concluded that aqueous extract of fruits of Garcinea pedunculatahas potent anti inflammatory activity and there is a need for further scientific investigation to explore its anti inflammatory activity.

  Isatin is an important class of heterocyclic compounds. Recently, heterocyclic compounds analogues and their derivatives have attracted strong interest in medicinal chemistry due to their biological and pharmacological properties. The small and simple isatin nucleus possesses numerous biological properties like -antitumor, antimicrobial, anti-inflammatory, anticonvulsant, antiviral, anti HIV, antioxidant, CNS depressant activities. These activities are also possessed by its substituted derivatives as well. The present review outlines some commonly used procedures to synthesize the isatin moiety and its derivatives, with different biological activities.
