The infraspecific taxonomy of wild Anacardium occidentale is little studied. We investigated whether wild populations on coastal dunes in Piauí, Brazil differed from non‐wild populations. Ten populations were sampled and twenty one morphological variables were measured. Variation within and between populations was investigated with univariate and multivariate statistics. Dune populations were mostly more similar to one another than to domesticated ones. There was significant correlation between inter‐population geographical distance and morphological dissimilarity. Classification methods showed 96.4% successful assignment to the dune category and 86% to 100% to dune populations individually, but dune and non‐dune populations overlap morphologically. Dune populations had shorter, broader leaves, shorter drupes and fewer secondary veins. Non‐dune coastal populations showed strongest similarity to dune populations. Populations distant from the coast were most divergent. The population from the cerrado region was most distinct, with thicker leaf blades and narrower petioles. The dune populations are recognised as the “restinga ecotype” of A. occidentale. Correlation of dissimilarity and distance may result from gene flow and/or non‐inherited environmental effects. Ecology and nomenclature (including the vernacular “cajuí”) of the restinga ecotype are reviewed. Further comparison of restinga populations is needed along the Brazilian coastline and with natural cerrado populations.

“…The anacardic acid content of the CNSL sample was 52.8%, as described by Agostini-Costa et al (2004), measured spectrophotometrically by interpolating the absorbance of the sample against a standard curve for anacardic acid (y = 0.1088 + 0.03102 x; r 2 = 0.9762) based on a series of graded concentrations of this substance (0,5; 1,0; 1,5; 2,0; 2,5 mg mL -1 ). It has a maximum UV-visible absorption between 280 and 320 nm, corresponding to cardol and anacardic acid, respectively.…”

ABSTRACT:Extracted from the fruit of Anacardium occidentale L., Cashew Nut Shell Liquid (CNSL) is a phenolic lipid that has potential biological use. Conventional pesticides are increasingly being replaced by natural products because of the impact that their mismanagement can have on human health and the environment. The objective of this work was to evaluate the fungicidal potential effect of CNSL on the fungi Colletotrichum gloesporioides and Lasiodiplodia theobromae, in particular its use in reducing negative impacts on fruit production. Chemical and physical tests were conducted to determine features of the sample, such as pH, electrical conductivity and solubility, and to measure its anacardic acid content. In vitro and in vivo tests were also conducted to evaluate the inhibition of mycelial growth on papaya fruit, the identification of volatile components and the inhibition of spore production. CNSL had the highest fungicidal potential for both fungi in vitro at a concentration of 320 µg mL -1 , and the same concentration was also maximal for sporulation inhibition in both fungi. In the in vivo tests the protective effect of CNSL was higher for C. gloesporioides fungus, whereas its curative effect was higher for L. theobromae. It was found that the substance with fungicidal potential was non-volatile and that the presence of the pathogens altered the chemical properties of the fruit.

“…Os ácidos anacárdicos, juntamente com os alquilresorcinóis, constituem cerca de 90% da composição do CNSL e apresentam propriedades tóxicas e irritantes. Porém, no pseudofruto, a proporção das substâncias fenólicas é muito baixa 59 . Além dos ácidos anacárdicos, os 1,3-diidroxi-5-alquilbenzenos, conhecidos como lipídios resorcinólicos (cardol), também ocorrem naturalmente em pequenas proporções não só em A. occidentale, como também em outras espécies da família.…”

Recebido em 18/5/05; aceito em 14/11/05; publicado na web 13/7/06 SECUNDARY METABOLITES FROM SPECIES OF ANACARDIACEAE. This review describes some aspects of the family Anacardiaceae dealing with the presence and distribution of secondary metabolites in the main genera of this family and their biological activities. It reports the occurrence of different natural compounds present in their species with special emphasis on phenolic lipids, flavonoids and triterpenes that are typical metabolites of this family.Keywords: Anacardiaceae; phenolic lipids; flavonoids. INTRODUÇÃOAnacardiaceae é uma família constituída por cerca de 76 gêne-ros e 600 espécies. Seus gêneros são subdivididos em cinco tribos (Anacardieae, Dobineae, Rhoeae, Semecarpeae e Spondiadeae). Cerca de 25% dos gêneros dessa família são conhecidos como tó-xicos e causadores de dermatite de contato severa. De modo geral, as espécies venenosas desta família estão restritas às tribos Anacardieae, Rhoeae e Semecarpeae 1,2 . A dermatite de contato provocada por essas plantas é atribuída principalmente a compostos fenólicos e catecólicos ou a mistura destas substâncias, denominados lipídios fenólicos. Estas substâncias podem estar presentes em diferentes partes do material vegetal, ocorrendo principalmente em espécies do gênero Rhus 3,4 . Nos últimos anos, a origem dos lipídios fenólicos e derivados também foi objeto de investigação; além disso, espécies da família Anacardiaceae têm se mostrado bastante promissoras na busca de substâncias bioativas. Do ponto de vista químico, os gêneros mais estudados nesta família são Mangifera, Rhus (Toxicodendron), Anacardium, Spondias, Lannea, Semecarpus, Schinus, Pistacia, Lithraea, Tapirira e Melanorrhoea. Mangifera, Rhus e Anacardium destacam-se pelo número de investigações relativas à composição química de suas espécies e atividades biológicas de seus extratos e metabólitos. Os estudos destas espécies possibilitaram verificar a ocorrência de flavonóides, terpenos, esteróides, xantonas e, principalmente, dos lipídios fenó-licos e derivados. Destaca-se que entre os flavonóides, os biflavonóides são os mais freqüentes.
