The jalapin-like chloroform-soluble material from the dried tubers of I. batatas was subjected to successive column chromatography over silica gel and HPLC to yield batatosides J-L (55-57) with the oligosaccharide core based on operculinic acid E. The lactonization site was placed at C-2 of the first rhamnose unit. Cinnamic acid was present as the esterifying residue at the C-2 position of the third rhamnose unit. These resin glycosides also contain esterifying residues composed of n-dodecanoic or (25)-methylbutyric acids at the C-2 or C-3 positions on the second rhamnose unit of the oligosaccharide core as well as n-decanoic or n-dodecanoic acids at C-4 on the third rhamnose (40). 

As reported for all pentasaccharides from sweet potato (64, 86), pure compounds 232 and 233 were also submitted to sapoiufication yielding simonic acid B (87). The liberated fatty acids were identified as isobutyric, (25)-methyIbutanoic, -decanoic, -dodecanoic, and cinnamic acids. The site of lactonization by the aglycone in the macrocyclic unit was placed at C-2 of the second saccharide. The position of the ester linkage on the macrocyclic unit was C-2 of the terminal rhamnose. The acylations were identified as follows for the macrocyclic unit at C-2 of the third saccharide (n-dodecanoic acid), and at C-3 and C-4 of the branched... 

Palmitic and stearic acids are the major saturated fatty acid constituents of most animal and plant tissues. Much smaller amounts of other saturated fatty acids are present in most natural sources. Low concentrations of myristic acid (n-tetradecanoic acid 14 0) and lauric acid (n-dodecanoic acid 12 0) have been detected in certain tissues.

Acids Originally Linked to Oligosaccharide Moieties of Resin Glycosides (yielded by alkaline hydrolysis). The vast majority of the stmcturally elucidated resin glycosides show acyl residues 0-linked to certain positions of one or more monosaccharide units. There are three types of acids which may contribute to the stracture (i) short-chain aliphatic acids (C -C for the most part volatile in steam), normally saturated, e.g. (25)-methylbutyric acid, except 2-butenoic acid (only found once) and tighc acid (ii) straight-chain saturated fatty acids (not volatile in steam), e.g. n-hexanoic acid (caproic acid), n-dodecanoic acid (lauric acid) (iii) arylalkyl acids, to date only represented by one example tra 5-cinnamic acid. Occurring acids are completely listed in Table 8.2.
