A phytochemical reinvestigation of the whole plant of Euphorbia segetalis yielded five tetracyclic triterpenes: 3beta-hydroxy-cycloart-25-en-24-one (1), cycloart-25-ene-3beta,24-diol (2), cycloart-23-ene-3beta,25-diol (3), lanosta-7,9(11),24-trien-3beta-ol (4) and lanosta-7,9(11),24(31)-trien-3beta-ol (5). beta-acetoxy-cycloart-25-en-24-one (1a) and glutinol (6), lupenone (7), dammaranodienol (9), cycloartenol acetate (10), 24-methylenecycloartanol acetate (11) and beta-sitosterol (12), isolated previously, were evaluated for their antiviral activities against Herpes simplex virus (HSV) and African swine fever virus (ASFV). Lupenone exhibited strong viral plaque inhibitory effect against HSV-1 and HSV-2. The in vitro antifungal and antibacterial activities of la, cycloart-23-ene-3beta,25-diol, 3-acetate (3a) and 6-12 were also investigated.
