Four new resin glycosides, namely, ipomotaosides A−D (14), were isolated from the dried aerial parts of Ipomoea batatas. The structures of 14 were elucidated by analysis of their spectroscopic data and by chemical derivatization and were tested for their anti-inflammatory activity against cyclooxygenase (COX)-1 and -2.
