As a cardiac principle of aconite root, Yokonoside had been reported by us in previous meeting, but synthesized Yokonoside did not have any biological activities. Then, separating procedure had been reinvestigated to obtain the true cardiac principle. In order to remove the inactive glycoside, the fractn. III was subjected to counter current distribution of n-buthanol-0.1N-HCl solvent system. And a crystalline matter (mp.260°), was obtained as colorless plate from the active fractn. IV as HCl-salt. The principle stimulates flog's heart even in ten billionth dilution, thus it was designated as Higenamine. Higenamine was identified as dl-demethyl coclaurine [V] from the spectral data and in comparison with synthesized authentic sample.

Aconite root (Bushi in Japanese) from Aconitum japonicum THUMB. has long been used as one of the most important herbs as a heart stimulant, diuretic agent ; and anodyne in Chinese medichine. Isolation and identification of the cardiac principle predicted by Yakazu are described. In the isolation process, the Yagi-Hartung method using frog heart was found to be useful for pharmacological measurement of cardiac activity of the material. The material was water soluble and was fairly unstable, especilly in a basic medium, and was tightly adsorbed on charcoal, alumina, silica gel, and cellulose powder, indicating that these agents are not useful for the separation. Isolation of the material was finally achieved by the limited combination of gel filtration through Sephadex LH-20 and counter current distribution, and colorless plates, mp 260°, were obtained as HCl salt. This principle stimulates frog heart even 1 : 10-9 dilution, and it was designated as Higenamine. Higenamine was identified as dl-demethylcoclaurine (II) from the spectral data and by comparison with synthesized authentic sample.

A Coryneform bacterium, isolated from the digestive gland of the Japanese ivory shell, Babylonia japonica, was shown to produce neosurugatoxin and prosurugatoxin, the causative toxins of a food poisoning outbreak in 1965 following ingestion of the shellfish. This is the first evidence that marine toxins may be produced by bacteria.
