Lichens are an important source of phenolic compounds and have been intensively investigated for their biological and pharmacological activities. Lecanoric acid (1), a lichen depside, was isolated from a Parmotrema tinctorum specimen and treated with alcohols to produce orsellinic acid (2) and orsellinates (3) to (9) (2,4-dihydroxy-6-n-methyl benzoates).(More)
UNLABELLED PREMISE OF THE STUDY Nine microsatellite (simple sequence repeat [SSR]) loci were characterized for natural populations of Piper solmsianum, a potential source of bioactive secondary metabolites, and analyzed to assess the levels of genetic diversity in this species. • METHODS AND RESULTS Based on an enriched library using the(More)

Piper L. is one of the largest genera of the Piperaceae family and abundant in the Neotropics, the South Pacifi c, and Asia ( Jaramillo et al., 2008 ). Some species are well known for their medicinal and commercial uses, such as P. nigrum L. (black pepper) and P. methysticum G. Forst. (kava-kava). Piper solmsianum C. DC. is a medium-sized shrub and(More)
