Triterpenoid cinnamate, acetate and palmitate from Hoya kerrii leaves

Publication date: October 2018Source: Phytochemistry Letters, Volume 27Author(s): Sudarat Kruakaew, Suriphon Singha, Chonticha Seeka, Wantana Mongkolvisut, Somyote SutthivaiyakitAbstractTwo new triterpenoid cinnamates, namely, 3β-O-D-friedours-11α,12α-epoxy-14-enyl cinnamate and 3β-O-29-nor-20-oxolupanyl cinnamate, as well as thirteen known compounds were isolated from hexanes extract of the leaves of Hoya kerrii. The structural elucidation of the compounds was performed using spectroscopic methods. Among several isolated triterpenoid cinnamates, lupeol cinnamate is known to possess strong anti-inflammatory properties. The presence of 3β-O-D-friedours-11α,12α-epoxy-14-enyl and 3β-O-D-friedoolean-11α,12α-epoxy-14-enyl esters has only been reported in a few species of Apocynaceae.Graphical abstract
