Abstract: A new linoleic acid derivative, was isolated from the lichen Sulcaria virens together with 12 known compounds. The structure of the new compound was determined as 9, 10-O-isopropyllidene -(12 Z)- en-octadecaoic acid (1) by spectroscopic analysis. Other 12 known compounds were ( 9 Z, 12 Z ) -octadecadienoic acid (2), evernic acid (3 ), ( R )- usnic acid (4), vulpinic acid (5), atranorin (6), virensic acid (7), abieslactone (8), 3α-hydroxylanosta-7, 24-dien-26, 23 R-olide (9), taraxerol (10), taraxerone (11), 5α, 8α-epidioxy -( 22 E, 24 R )-ergosta-6, 22-dien-3β-ol (12 ), 2, 2′-tetrahydrosqualene (13).
