been obtained containing up to 43 [ig. of this substance per g. of fruit. 

 The last material in this series reported by Porter and Lincoln ^*« is 

 tetrahydrophytoene (i.e., eicosahydrolycopene). Little information about 

 this highly saturated carotenoid is available at present but it apparently 

 absorbs light at 220 m(x.
