Two new resin glycosides, muricatins XII and XIII, from the seeds of .

Two new resin glycosides, muricatins XII () and XIII (), were isolated from the crude resin glycoside fraction of the seeds of (L.) Jacq. (Convolvulaceae), along with three known ones, muricatins V (), VI (), and IX ().

A New Glycosidic Acid, Muricatic Acid D, and Resin Glycosides, Muricatins X and XI, from the Crude Resin Glycoside Fraction of the Seeds of Ipomoea muricata.

Alkaline hydrolysis of crude resin glycoside fraction of the seeds of Ipomoea muricata (L.) Jacq. (Convolvulaceae) yielded a new glycosidic acid, muricatic acid D; three known glycosidic acids, namely, muricatic acids A, B, and C; and three known organic acids, namely, isobutyric, 2S-methylbutyric, and 2S-methyl-3S-hydroxybutyric acid.

A New Resin Glycoside, Muricatin IX, from the Seeds of Ipomoea muricata.

A new resin glycoside, named muricatin IX (1), was isolated from the seeds of Ipomoea muricata (L.) JACQ. (Convolvulaceae).
