  Three fatty acid glycosides, designated pescaprosides A, B, and E, have been isolated from Ipomoea pescaprae (family Convolvulaceae). Chemical studies on pescaproside E, the major product, led to its characterisation as a pentaglycoside of 11-hydroxyhexadecanoic acid. Its sugar chain was esterified with 2-methylbutanoic and lauric acids. The structure of the pentaglycoside has been established as O-α-l-rhamnopyranosyl-(1→3)-O-[α-l-rhamnopyranosyl-(1→4)]-O-α-l-rhamnopyranosyl-(1→4)-O-β-d-fucopyranosyl-(1→2)-O-α-l-rhamnopyranosyl-(1→11)-oxyhexadecanoic acid.

  Four fatty acid glycosides, designated dichrosides A, B, C, and D, have been isolated from Ipomoea dichroa (family, Convolvulaceae). On chemical investigation, dichroside D was found to be a pentaglycoside of 11-hydroxyhexadecanoic acid, and the sugar chain is highly esterified with other fatty acids. The structure of the pentaglycoside has been established as 11-{O-β-d-glucopyranosyl-(1→4)-O-[β-d-fucopyranosyl-(1→3)]-O-α-l-rhamnopyranosyl-(1→4)-O-α-l- rhamnopyranosyl-(1→2)-α-l-rhamnopyranosyl)oxy}hexadecanoic acid.
