ABSTRACT:Drug abuse is the willful misuse of either licit or illicit drugs for the purpose of recreation, perceived necessity or convenience. Drug abuse is a more intense and often willful misuse of drugs often to the point of addiction. In the eastern world the incidence shows a decline or a static pattern but the number of drug addicts is still enormous.. The major drug of abuse are heroin and marijuana but designer drugs are shown to be on the increase. The aim of the study is to determine the ratio of the drug abuse in student. For this purpose we selected different institutions including “the university of Lahore”, “Forman Christian college”(private sector) and Punjab university(Govt sector) and conducted survey in 500 student. High proportion of students was found abusing drugs. From this study, we came across multiple factors which are the main cause of drug abuse in medical student including depression, anxiety, schizophrenia, as well as personality disorder like antisocial personality disorder. The most commonly abused drugs include stimulants, opioids, and benzodiazepines, antihistamines. Although survey have indicated high rate of illicit and prescription drugs misuse among college students, few have assessed the negative consequences, personel concerns, or interest in intervention for drugs use. Drug abuse although regarded as a personality disorder, may also be seen as worldwide epidemic with evolutionary genetic, physiology and environmental influences Controlling and affecting human behavior. Globally, the use has reached all time high. The study showed males are more drug abusers as compared to females. The drug abuse ratio in students of private sector is more as compared to Govt sector.

This study evaluates the antioxidant activity of Ranunculus muricatus and isolation and structure elucidation of the active constituents. The aerial parts of the plants were shade dried at room temperature and powdered and extracted with methanol. The free radical scavenging activity was evaluated by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay. The percentage scavenging activity was determined based on the percentage of DPPH radical scavenged. Column chromatography was used in order to isolate the active compounds. Spectral techniques UV, IR, 1H NMR, 13CNMR and HREI-MS were used for the structure elucidation of the isolated compounds. Two isolated compounds, A (caffeoyl-β-d-glucopyranoside) and B (1,3-dihydroxy-2-tetracosanoylamino-4-(E)-nonadecene), exibited a significant antioxidant activity as showed by DPPH radical scavenging method. Percentage inhibition for compound A (at 0.5 mM) was 82.67 ± 0.19 with IC50 of 93.25 ± 0.12 (μM), and for compound B (at 0.5 mM) was 69.23 ± 0.19 with IC50 of 183.34 ± 0.13 (μM). Quercetin was used as standard control. It was conclued from the present study that caffeoyl-β-d-glucopyranoside and 1,3-dihydroxy-2-tetracosanoylamino-4-(E)-nonadecene isolated from methanol extract of aerial parts of Ranunculus muricatus posses antioxidant activity.
