Alkyl‐and alkenylresorcinols inRapanea laetevirens seed lipids
Lipids, 1977AbstractThe seed lipids ofRapanea laetevirens (Myrsinacea) were found to contain a series of 5‐alkylresorcinols. Some of these alkylresorcinols have been reported previously in other plant families, but never before in the Myrsinaceae. The various homologs were shown by mass spectrometry to have alkyl side chains that included C11 and C13 saturated as ...

Sub-acute toxicity of the chloroformic extract of Rapanea melanophloeos (L.) Mez in rats
Journal of Ethnopharmacology, 2014Cape beech (Rapanea melanophloeos) is an important medicinal plant that is widely used in most of Africa. Currently, little toxicological information is available on its safety following prolonged use.In this study, we sought to evaluate the oral sub-acute toxicity of Rapanea melanophloeos stem bark chloroformic extract using Sprague Dawley rats.Six ...

—The already known benzoquinone, embelin (mixed with rapanone), and two new benzoquinones, myrsinone and myrsinaquinone, were isolated from the Myrsinaceae plant, Rapanea melanphloes (L), Mez. All the three compounds showed antifeedant activity when bioassayed on nymphs of the desert locust, Schistocerca gregaria (Forsk).

Perforated ray cells are reported for the first time in stern and root wood of two neotropical species, Rapanea laetevirens Mez and Rapanea lorentziana Mez (Myrsinaceae). Two types of ray splitting were observed. One of them is correlated with the presence of perforated ray cells.

This study was conducted to generate a toxicological profile of Rapanea melanophloeos, a medicinal plant widely utilized in traditional medicine to treat helminthiasis,using brine shrimp (Artemia salina) and Sprague Dawley (SD) rats. The aqueous extract showed potent in vitro toxicity to brine shrimp with a median lethal concentration (LC50) of 59.37μg/
