TL;DR: In this paper, the stereostructures and molecular conformations of six diterpene lactones, gelomulides A-F, isolated from the leaves of Gelonium multiflorum were established on the basis of NMR, mass spectral and chemical evidence.

TL;DR: In this article, the structures of lagerenyl acetate and Lagerenol with the cycloartane skeleton were established as 3β-acetoxycycloart-24-one and 3 β-hydroxymethylcarboxylate 24-one, respectively, on the basis of spectral and chemical evidence.

TL;DR: Defuscin, a new phenolic ester shown to be n -triacontyl p -coumarate, and (−)-shikimic acid have been isolated from the whole plant of Dendrobium fuscescens Griff as mentioned in this paper.

TL;DR: The structure of murrangatin, a monomeric coumarin isolated from the leaves of Murraya elongata, has been elucidated by spectroscopic and chemical evidence, and confirmed by its chemical correlation with phebalosin this article.
