Chemical Constituents From Roots of Duguetia furfuracea (a. St.-Hil.) Saff. (Annonaceae)

Biochemical Systematics and Ecology, 2019
Abstract The phytochemical investigation of roots of Duguetia furfuracea (A. St.-Hil.) Saff. (Annonaceae) led to the isolation of α-asarone (1), asaraldehyde (2), staudine (3) and a mixture of β-sitosterol 3-O-β-D-glucopyranoside (4) and stigmasterol 3-O-β-D-glucopyranoside (5).

Flavonoids From Leaves of Duguetia furfuracea

Revista Caderno Pedagógico
This study investigates the phytochemical profile of the leaves of Duguetia furfuracea, a shrub native to the Brazilian Cerrado and traditionally used in folk medicine for the treatment of dysmenorrhea, diarrhea and rheumathism, stomach pain, renal colic, spine pain and soothing. The leaves were extracted with a mixture of ethanol/ water (8:2), and the

Isolation of a minor nitro-alkaloid from the aerial parts ofDuguetia furfuracea– Annonaceae

Natural Product Research, 2009
The refractionation of an alkaloidal extract of the leaves and twigs of Duguetia furfuracea has provided a minor aporphinoid alkaloid, named (+)-8-nitrous-isocorydine or (+)-1,2,3-trymethoxy-11-hydroxy-8-nitrous- aporphine. The structure of the new compound was elucidated by spectroscopic methods, notably 2D NMR and HRESIMS.

Alkaloid Fraction of Duguetia furfuracea Demonstrated Anti-Inflammatory and Antinociceptive Effects Through Decrease of Tumour Necrosis Factor Alpha in Mice Models

Inflammopharmacology
Duguetia furfuracea, popularly known as "araticum-seco," is traditionally used in folk medicine for the treatment of pain and inflammatory disorders. This study aimed to analyze the chemical composition and investigate the anti-inflammatory and antinociceptive activities of the alkaloid fraction obtained from the leaves of D. furfuracea (DfFAlk).

Antioxidant, anti-rheumatic and anti-inflammatory investigation of extract and dicentrinone from Duguetia furfuracea (A. St.-Hil.) Benth. & Hook. f.

Journal of Ethnopharmacology, 2018
The preparations of teas and syrups using Duguetia furfuracea have been used in folk medicine to treat rheumatism and back pain. Several rheumatic diseases are anti-inflammatory and are treated with several anti-inflammatories.The objective of this work were to evaluate the chemical investigation of methanolic extract obtained from leaves of D ...

Karyological Races and Ecology of the Brazilian Duguetia furfuracea as Compared With Xylopia aromatica (Annonaceae)

Flora, 1984
Summary D. fufurcaea , a highly adapted pyrophyte of the Central Brazilian savanna vegetation contains three karyological races (2n = 16, 24, 32) which are to some extent geographically and ecologically differentiated. The forest species D. cf. lanceolata and D. cf. salicifolia have chromosome numbers of 2n = 16.

N-Nitrosoanonaine and N-Nitrosoxylopine, Aporphine Alkaloids from Duguetia furfuracea

Journal of Natural Products, 2006
Two new aporphine alkaloids, N-nitrosoanonaine (1) and N-nitrosoxylopine (2), were isolated from the aerial parts of Duguetia furfuracea, a weed found in several Brazilian regions. Their structures were elucidated by NMR analysis, CHN analysis, CD, IR, and MS data.
