Isolation and Identification of -Clerodane Diterpenes from Makino
Natural Product Communications, 2006 An extract of the aerial parts of Ajuga nipponensis Makino was examined by HPLC for neo-clerodane diterpenes. The suitability of reversed-phase HPLC for the semi-preparative fractionation of this extract was explored, resulting in the isolation of two ...

Eperua oleifera Ducke (Fabaceae) Oilresin Chemical Composition and the Isolation of a Natural Diterpenic Acid Methyl Ester. [PDF]
Chem BiodiversEperua oleifera (Fabaceae) oilresin presents not only diterpenic acids, but also diterpenic acid methyl ester. ABSTRACT Eperua oleifera Ducke, commonly known as “copaíba‐jacaré,” produces oilresins traditionally used in folk medicine for wound healing and as antifungal and antibacterial agents, similar to those of Copaifera species.

Consequences of interspecific plant hybridization on metabolic diversity in naturally occurring hybrid swarms. [PDF]
Plant JSignificance Statement Studies on the effect of hybridization on plant chemistry have mainly been conducted with crop plants and artificially created hybrids, and the few studies that have analyzed naturally occurring hybrids have either examined only a small number of plants and/or only a small number of metabolites.
