Genetic diversity and mating system of Copaifera langsdorffii (Leguminosae/Caesalpinioideae)

Abstract

ABSTRACT. Copaifera langsdorffii, locally known as copaíba, is a valuable tropical tree with medicinal properties of its oil. We studied the genetic variation, genetic structure, and the mating system of trees in stands of C. langsdorffii (Leguminosae/Caesalpinioideae) located in an extensive area between the Pardo and Mogi-Guaçu basins in São Paulo State, Brazil, and their offspring, conserved in an ex situ germplasm bank at the University of São Paulo in Ribeirão Preto, SP, Brazil, using six microsatellite loci. Leaves were collected from 80 seed trees and from 259 offspring and their DNA extracted. A total of 140 and 175 alleles were found in the seed trees and their offspring, respectively. Low genetic differentiation was observed between stands, indicating intense gene flow due to efficient pollen dispersion vectors. An estimation of the outcrossing rate showed that these stands are outcrossed (t m = 0.98, P > 0.05). The mean variance of the effective population size of each family in two of the stands was 3.69 and 3.43, while the total effective population size retained in the germplasm bank was between 81 and 96. The paternity correlation was low, ranging from 0.052 to 0.148, demonstrating that the families implanted in this germplasm bank are composed predominantly of half-sibs.

Antigenotoxicity properties of Copaifera multijuga oleoresin and its chemical marker, the diterpene (−)-copalic acid

“…Plants, vegetables, and spices used in folk and traditional medicine have gained wide acceptance as one of the main sources for discovery and development of chemopreventive drugs (Aruoma et al 2006;Farombi and Owoeye 2011;Niwa et al 2016). Copaiba oil, extracted from trees of the genus Copaifera (family Leguminosae-Caesalpinoideae), has become important in Brazilian herbal medicine (Gonela et al 2013). Different ethnopharmacological properties of the oil, such as anti-inflammatory, wound healing, antitumor (Leandro et al 2012), trypanocidal (Izumi et al 2013), and antimicrobial activity (Bardají et al 2016), have been documented.…”

Effects of the topical administration of copaiba oil ointment (Copaifera langsdorffii) in skin flaps viability of rats

“…Copaiba oil, extracted from trees of the genus Copaifera, from the family legumonosa-caesalpinioideae is a substance which has become very important in Brazilian Natural Medicine 15,16 . Its effects as a healing substance and as an anti-inflammatory agent have been studied in many experimental models.…”

Study of copaiba oil on behavioral testing in rodent models by inducing neuropathic and inflammatory pain

“…The oil-resin of this plant is a popular remedy, in its natural form. Copaifera officinalis was the first species in the genus Copaifera to be described [6][7][8]. Many studies using experimental pharmacological models have established the anti-inflammatory, gastroprotective, wound healing and others activities of copaiba oil [9][10][11][12][13].…”
