5,6,8,13-Tetrahydro-2,3-dimethoxy-9,10-(methylenedioxy)-13aH-dibenzo[a,g]quinolizine

A berberine type alkaloid, first isolated from Sinorneniurn acuturn Rehd. and Wits and also present in both the (-)- and (±)-forms in Fagara officinalis L., crystallizes from EtOH in colourless prisms. It has [α]_D - 312° (CHC1₃ ) and yields a sparingly soluble hydrochloride, m.p. 272°C (dec.) and a platinichloride, m.p. 245-7°C. On oxidation with iodine in EtOH it forms an iodide as orangeyellow needles, m.p. 300°C (dec.) which, on treatment with silver chloride in H₂ 0 gives dehydrosinactine chloride, identical with epiberberinium chloride.

ChEBI: Sinactine is an alkaloid.
