Abstract: Vitex pseudo-negundo, as a medicinal plant, grows naturally in several regions of Asia. Several pharmaceutical and medicinal properties of this species prompted us to investigate constituents and quantity of essential oils in different parts of this species. According to our findings, limonene, myrcene, and caryophyllene oxide were the major constituents of oil extracted from leaf, flower, and gramineous stipes, respectively, of Vitex pseudo-negundo collected from Sabzevar province at the north of Iran.
