• 개요

  This base occurs in the fruit of Capparis torrnentosa, Citrus grandis and in Stachys tubi/era Naudin. It normally crystallizes as the monohydrate which has m.p. 116-8°C. The specific rotation is [α]>_D- 40.25° (c 4.0, H20). It is soluble in EtOH and H20, insoluble in CHC13 and Et20. The free base is unstable in air and decomposes quite rapidly. The hydrochloride yields colourless crystals from EtOH with m.p. 222°C; [α]²⁰_D - 28.1° (c 4.83, H20); aurichloride, m.p. 232°C; platinichloride, decomposing at 200°C; oxalate, colourless needles, m.p. 105- 7°C and the picrate, m.p. 199-2000 C. The structure is that of the methylbetaine of hygric acid.
