摘要本文综述了杨桃C13 <$norisoprenoid香气物质形成的研究。杨桃中的大多数降异戊二烯挥发物来自糖苷结合的祖细胞，这一发现刺激了对果实糖苷部分的更深入研究。本文报道了杨桃中几种新的C13-和C15-降异戊二烯结构的分离和结构鉴定，并讨论了杨桃中形成有效香气化合物的降解途径。在最后一部分中，注意力集中在杨桃中类胡萝卜素分解的可能途径上，从而合理化C13-和C15-norisoprenoids与显然来自类胡萝卜素链中心部分的挥发物的共存。
Abstract This paper summarizes our studies on the formation of C13‐noriso‐prenoid aroma substances in starfruit (Averrhoa carambola L.). The finding that the majority of norisoprenoid volatiles in starfruit are derived from glycosidically bound progenitors stimulated more intense studies into the glycosidic fraction of the fruit. In this paper the isolation and structural elucidation of several novel C13‐ and C15‐norisoprenoid structures in starfruit is reported and the degradative pathways giving rise to the formation of potent starfruit aroma compounds are discussed. In the last part, attention is focused on possible pathways of carotenoid breakdown in starfruit, thus rationalizing the co‐occurrence of C13‐ and C15‐norisoprenoids with volatiles apparently derived from the central portion of the carotenoid chain.
