The biosynthesis of andrographolide begins with the addition of IPP to DMAPP, which forms geranyl pyrophosphate. Another molecule of IPP is then added, yielding farnesyl pyrophosphate (FPP). The final IPP molecule is added to the FPP to complete the backbone of the diterpene. The double bond originating from DMAPP is oxidized to an epoxide prior to the ring closing cascade that forms two six-membered rings. A series of oxidations form a five-membered lactone in addition to adding on the alcohol groups. The order of these post-synthetic modifications is not entirely known.<ref name=Srivastava/>
