The investigation of EtOAC of branches and leaves of Glycosmis parva Craib [1, 2] (Rutaceae) collected in Thailand led to the isolation of a new acridone alkaloid, glycosparvarine (1), three new sulfur-containing propanamide derivatives, (+)-S-deoxydihydroglyparvin (2), (+)-S-deoxytetrahydroglyparvin (3) [3] and (+)-tetrahydroglyparvin (4), together with nine known compounds (N-methylatalaphylline, N-methylcyclo-atalaphylline-A, glycofolinine, citramine, arborinine, limonin, a mixture of limonexic acid and isolimonexic acid, glyparvin-A and dihydroglyparvin). Antiviral activity evaluation of isolated compounds against herpes simplex virus (HSV) type 1 and 2 disclosed that glycosparvarine (1), (+)-tetrahydroglyparvin (4) and glycofolinine, showed moderate inhibitory activities with EC50 of 348, 229 and 151 µM, respectively. In addition, (+)-S-deoxydihydroglyparvin (2) exhibited activities with EC50 of 29.8 and 44.6 µM against HSV-1 and HSV-2, respectively.
