Sudachiin A was isolated from the green peels of Citrus sudachi Hort. ex Shirai. This structure was deduced to be sudachitin 4′-β-d-glucoside by means of its spectra and degradation; this was confirmed by the synthesis of the one from sudachitin 7-benzyl ether and α-acetobromoglucose via several steps. 4′,5,7-Trihydroxy-3′,6,8-trimethoxyflavone 7-glucoside (sudachitin 7-β-d-glucoside), which was isolated from Sideritis leucantha Cavanilles, was also synthesized from sudachitin and α-acetobromoglucose in a similar manner.
从Citrus sudachi Hort.通过光谱和降解推断其结构为须达吉苷 4′-β-d-葡萄糖苷,并由须达吉苷 7-苄基醚和α-乙酰溴葡萄糖经多个步骤合成证实了这一结构。4′,5,7-Trihydroxy-3′,6,8-trimethoxyflavone 7-glucoside (sudachitin 7-β-d-glucoside) 也是从 Sideritis leucantha Cavanilles 中分离出来的,也是用类似的方法从胭脂树素和α-乙酰溴葡萄糖中合成的。
