Phloroglucinols from Myrtaceae: attractive targets for structural characterization, biological properties and synthetic procedures

Myrtaceae Juss. is a very large family of flowering plants, that are a valuable source of bioactive compounds. From the phytochemical point of view, apart from ubiquitous tannins, flavonoid derivatives and volatile oils, Myrtaceae plants are very rich in phloroglucinol derivatives, divided in two principal subclasses: oligomeric acylphloroglucinols and phloroglucinol-terpene adducts. Despite this large structural variability, many studies on...
