Artemisia annua L. cultivar jwarharti (Asteraceae) is an aromatic annual herb up to 2 m in height found in temperate Asia, especially China and naturalized in many countries of the world. The plant is prescribed against fever, malaria, skin diseases, jaundice, malignant ulcers and haemorrhoids. Phytochemical investigation of the methanolic extract of the shoots of A. annua var. jwarharti led to the isolation of three new chemical constituents characterized as 5, 7, 4′- trimethoxy-8,3′'-dihydroxyflavone (2), 3,4-dihydroxybenzyl 2′,3′,4′-trihydroxybenzoate (3) and 3,4-dihydroxybenzyl 2′,3′,4′-trihydroxybenzoate 4,4′-β-D-dixylopyranoside (4) along with the known compound stigmasterol. The structures of all these phytoconstituents have been identified on the basis of spectral data analysis and chemical reactions.
