Alcaloides e outros constituintes de Xylopia langsdorffiana (Annonaceae)

Abstract

Recebido em 10/10/08; aceito em 26/2/09; publicado na web em 3/7/09 ALKALOIDS AND OTHER CONSTITUENTS FROM Xylopia langsdorffiana (ANNONACEAE). The phytochemical investigation of Xylopia langsdorffiana led to the isolation of corytenchine, xylopinine, discretamine, xylopine, ent-atisan-16α-hydroxy-18-oic acid, 13 2 (S) hydroxy-17 3 -ethoxyphaephorbide and quercetin-3-α-rhamnoside. Their structures were assigned based on spectroscopic analyses, including two-dimensional NMR techniques. Antioxidant activities of discretamine were measured using the 1,2-diphenyl-2-picryl-hydrazyl (DPPH) free radical scavenging assay.

Antinociceptive and anti-inflammatory activities of ethanolic extract from atemoya (Annona cherimola Mill x Annona squamosa L.)

“…From the phytochemical perspective, many secondary metabolites classes were found in the Annonaceae family. Chemotaxonomic data characterize this family for the presence of alkaloids, flavonoids and terpenoids, mainly diterpenes (Silva et al, 2009). Considering that the most important painkillers prototypes (salicylic acid and morphine) were derived originally from the plant kingdom, the study of medicinal plants has become a useful strategy in the search for antinociceptive drugs (Elizabetsky et al, 1995).…”

Phytochemical screening, cytotoxicity and acute toxicity of Annona vepretorum Mart (Annonaceae) leaf extracts

“…In Brazil there are about 29 genera and about 260 species, the majority occurring in forests, with few representatives in open areas [3]. This family is characterized by the presence of terpenoids (mainly diterpenes), alkaloids (particularly isoquinoline derivatives) and essential oils with predominant composition of monoterpenes and sesquiterpenes [4,5]. Another class of substances found in this family is the acetogenins of Annonaceae, which have many biological activities, and one of the most important is the antitumor activity [6].…”

Chemical composition of the volatile oil of Cardiopetalum calophyllum collected in the Cerrado area

“…However, the active substances present in the plants of this family are still investigated (NASCIMENTO et al, 2003;SILVA, 2007;NUNES et al, 2012;ALMEIDA et al, 2014;KRINSKI et al, 2014). C. calophyllum is a semideciduous species flowering between the months of August and October, with the peak flowering in September and fruiting between the months of January and April (SILVA et al, 2009;ELIAS, 2010). C. calophyllum is represented by trees and shrubs with heights ranging from 1.5 to 12m, commonly known as imbira, imbirinha, coast pepper, red pepper, among others (FECHINE et al, 2002;SILVA et al, 2009).…”

Several communities use C. calophyllum to treat some diseases such as bronchitis, sinusitis, dysmenorrhea, and fever, and as a carminative, both in the form of syrup and tea (NASCIMENTO et al, 2003;COELHO et al, 2009;COSTA, 2011;COSTA et al, 2013).…”
