Analgesic effect of Dioclea grandiflora constituents in rodents

Journal of Ethnopharmacology, 1995
An aqueous fraction and dioclein (5,2',5'-trihydroxy-6,7-dimethoxyflavanone) obtained from the ethanolic extract of the Dioclea grandiflora were tested for their analgesic effect in mice and rats employing acetic-induced writhing and tail flick tests, respectively.

Studies on the Starch of Dioclea violacea

Starch - Stärke, 1974
AbstractThe seeds of Dioclea violacea contain almost 50% of starch (dry basis). This starch presents some rounded granules, and other of oval or irregular shape, measuring 22–55 μ in lenght and 21–52 μ in width. It contains approximately 27.5% of amylose and its temperature of gelatinization is very similar to that of corn starch. The X‐ray diffraction

A-type proanthocyanidin antioxidant from Dioclea lasiophylla

Phytochemistry, 2000
The A-type proanthocyanidin, epigallocatechin-(2beta-->7,4beta-->8)-epicatechin, together with the known epicatechin, luteolin 3'beta-D-glucopyranoside, chrysoeriol 7beta-D-glucopyranoside and 2-methylpentan-2,4-diol, were isolated from leaves of Dioclea lasiophilla. The structures were established on the basis of their spectral data.

Isolation and characterization of a lectin from the seeds of Dioclea lehmanni

Phytochemistry, 1990
Affinity chromatography of the globulin fraction from the seeds of Dioclea lehmanni on Sephacryl S-200 yielded two lectins, one slightly retarded and another strongly bound. The latter, which was a glucose/mannose specific lectin, was purified and the following properties were determined: pI, Mr of subunits, carbohydrate content, A, aminoacid ...

Dioflorin, a Minor Flavonoid from Dioclea grandiflora

Journal of Natural Products, 1998
Dioflorin (1) was isolated as a minor constituent from the rootbark of Dioclea grandiflora, the crude extract of which demonstrated analgesic activity. The structure of 1 has been determined to be 5,7,2'-trihydroxy-8-methoxy-6-(3-methyl-2-butenyl)flavanone on the basis of spectral analysis.

Isolation and characterization of a lectin from the seeds of Dioclea grandiflora (Mart.)

Planta, 1983
By a combination of solubility fractionation, affinity and molecular-sieve chromatography, a lectin preparation containing several closely related lectin components of different isoelectric point was isolated from the seeds of Dioclea grandiflora Mart. The lectins showed a carbohydrate specificty for D-mannose (D-glucose)-binding and had a requirement ...

Flavonoids from the root-bark of Dioclea grandiflora

Phytochemistry, 1999
Abstract The systematic investigation of the root-bark of Dioclea grandiflora permitted the isolation of three new flavanones: agrandol (5,7-dihydroxy-6-methoxy-8-prenylflavanone), paraibanol (3,5,7,2′,5′-pentahydroxy-6-methoxyflavanone), and diosalol (3,5,7,2′,5′-pentahydroxy-6-methoxy-8-prenylflavanone). Also identified were β-amyrin and 5,7,2′,5′
