DOCUMENT TYPE: Journal CA Section: 3 (Biochemical Interactions) Treatment of marsh white seedless grapefruit with the 2-diethylaminoethanol esters of several acids, in particular 2-diethylaminoethyl hexanoate [10369-83-2], 2-diethylaminoethyl 4-phenylbutyrate [14007-64-8], and 2-diethylaminoethyl cinnamate [10369-88-7], caused the accumulation of large amts. of . 63677-28-1 is the cas registry number of certain chemical which is used as reagents here.beta.-carotene [7235-40-7]. The effects of the hexanoate and of 2-phenoxytriethylamine [74-40-8], which causes only lycopene [502-65-8] accumulation, were studied as functions of time. The hexanoate caused the rapid accumulation of lycopene during the 1st day. The amt. of lycopene then began to decrease and that of .beta.-carotene increased until, after 14 days, .beta.-carotene was the major pigment. 2-Phenoxytriethylamine caused rapid lycopene accumulation during the 1st day and a slow steady increase afterwards. Thus, the mode of action of the .beta.-carotene inducers may be similar to that of the lycopene inducers except that the former are probably rapidly hydrolyzed by the esterase(s) in the flavedo, so that they no longer inhibit the cyclase(s), and .beta.-carotene is accumulated at the expense of lycopene. .
