✦ Synopsis

Recently, much attention has been focused on the existence of spectrally characteristic W-absorbing substance in algae. There are, however, few reports concerning their chemical and physiological properties. Now we have isolated an optically active and water-soluble compound with a sharp absorption maximum at 320 nm from the red alga Chondrus yendoi which was collected at the shore of Zenikamezawa, Hakodate, Japan. More recently, three mycosporines having a absorption maximum at 310 nm have been isolated, from Stereum hirsutum, Botrytis cinera, and Palythoa tuberculosa, and named mycosporine 1, mycosporine 2 11

, and mycosporine-Gly 1, , respectively. The present communication describes isolation and structure of a new mvcosoorine iminomycosporine-Gly designated as palythine <*.
