octadecanoyl moiety, and by an ester linkage between the C-2 hydroxy group of the glucose moiety and the carboxyl group of the oxygenated octadecanoic acid. The structures of the cyclic fatty acyl glycosides were further distinguished from one another by acetylation and/or malonylation on the glucose moiety. Of these compounds, the 1,2'-cyclic ester of 12(R)-(6-O-acetyl-3-O-malonyl-beta-D-glucopyranosyloxy)octadecanoic
Silene gallica L.(石竹科)的腺毛状体渗出液的化学研究导致分离出 10 种环状脂肪酰基糖苷(gallicasides AJ)。环状结构的特征在于葡萄糖部分与十八酰基部分的 C-12 或 C-13 位的糖苷键,以及葡萄糖部分的 C-2 羟基与羧基之间的酯键含氧十八烷酸。环状脂肪酰基糖苷的结构通过葡萄糖部分的乙酰化和/或丙二酰化进一步相互区分。在这些化合物中,12(R)-(6-O-乙酰基-3-O-丙二酰-β-D-吡喃葡萄糖基氧基)十八烷酸的 1,2'-环酯 (gallicaside J) 含量最高 (30.7%) )。
