    Product Description

    α-Terpinene is a terpenoid that has been found in Cannabis and has diverse biological activities, including acaricidal, antiprotozoal, and antioxidant properties.1,2 α-Terpinene induces 99 and 46% mortality of male and female T. putrescentiae larvae, respectively, when administered at a dose of 32.3 µl/L via inhalation.3 In mice infected with T. evansi, it increases longevity when used alone and decreases mortality when used in combination with diminazene aceturate (Item No. 18678).4 It also scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; Item No. 14805) radicals when used at a concentration of 10 mM.5
