Investigation on Antimicrobial Activities of Essential Oil and Extract from Fresh Peel of Citrus hystrix DC. (shauk-nu)

Citrus hystrix DC. locally known as shauk-nu belonging to Rutaceae family has been chosen to investigate some chemical analysis and antimicrobial activity on its fresh fruit peel. Phytochemical investigation reveals the presence of alkaloids, α-amino acids, carbohydrates, flavonoids, glycoside, phenolic compounds, reducing sugars, saponins, steroids, tannins and terpenoids. However, cyanogenic glycosides were absent by using the standard methods. In addition, 5.6 % of the essential oil content was extracted from fresh fruit peel of shauk-nu by steam distillation method.
