Abstract

Chemical investigation of the dichloromethane extracts of the flowers of Dendranthema grandiflora cv. Yoko Ono afforded a new sesquiterpene lactone, grandiflorolide (1), 1,2-dilinoleoyl-3-linolenoylglycerol (2), a mixture of pseudotaraxasterol (3a), taraxasterol (3b), β-amyrin (3c), α-amyrin (3d), and lupeol (3e) in about 2:1:1:0.5:0.5 ratio, and another mixture of β-sitosterol (4a) and stigmasterol (4b) in about 2:1 ratio. The structure of 1 was elucidated by extensive 1D and 2D NMR spectroscopy, while those of 2–4b were identified by comparison of their NMR data with literature data. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
