Other claims from this paper (9)
- Observation Thirty-five lipophilic phenolic compounds were isolated and identified.
- Observation Chalcones were the largest constituent group, with 10 compounds.
- Observation Seven flavanones were found.
- Observation Four flavones were found.
- Observation Three benzophenones were found.
- Observation Three phloroglucinol derivatives were found.
- Observation Many flavonoids had unsubstituted B-rings or prenyl or neryl substituents.
- Observation The studied Helichrysum species had very similar lipophilic phenolics to African species.
- Mechanism The authors interpret these phenolics as conservative characters retained during the origin of Madagascar endemic taxa.
