Cassaide

In addition to eight known compounds three new alkaloids were isolated from the bark of this tree. They are cassamide (77), erythro-phlamide (78), and cassaide (79) (94). 

Cassaidine, C24H41O4N 4), on acid hydrolysis also provides j8-di-methylaminoethanol and the acid, cassaidic acid, C20H32O4. Adihydroxy-cassanic acid and a diketocassanic acid can be obtained from cassaidic acid which are identical with samples prepared from cassaic acid. Thus the relationship between cassaic acid and cassaidic acid (consequently cassaine and cassaidine) is that the keto group in the former is found as a hydroxy function in the latter.
