A novel aziridine compound N -acetyl-1,2-azacyclo- p -menthane d was synthesised using turpentine as raw material and characterised by FT-IR, 1 H NMR, 13 C NMR, ESI + -MS and HRMS. The pre-emergence herbicidal activities of d and its synthetic intermediates cis- and trans- N , N ′-diacetyl- p -menthane-1,8-diamine ( b2 and b1 ) were determined. The result showed that d exhibited much higher herbicidal activities against annual ryegrass, Digitaria sanguinalis and Ixeris denticulate than b2 and b1 . The IC 50 of d against the root and shoot growth of these three plants were lower than 1 mmol L −1 . In contrast, the IC 50 of b1 and b2 against the root and shoot growth of these plants were more than 10 mmol L −1 . Transformition of turpentine into N -acetyl-1,2-azacyclo- p -menthane ( d ).
