Description
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° (CHC1
3 ) 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 H
2 0 gives dehydrosinactine chloride, identical with epiberberinium chloride.
