Abstract:

An extract of Ryania speciosa, which assayed about 30 ryanodine, showed very high enzyme inhibitory activity. Two other varieties of Ryania examined, namely R. tormentosa and R. subuliflora, which had much lower inhibitory values, contained little or no ryanodine. This lends support to the idea that the hydrophilic inhibitory factor, which occurs in the ryanodine fraction and which still shows the ryanodine spectrum in the ultraviolet region, is a ryanodine-like substance.
