crotalaria lachnocarpa/inflammation

The aerial parts of Crotalaria emarginella Vatke (Leguminosae) has afforded two triterpenes, characterized as 3alpha-hydroxy-arbor-12-ene-28-carboxylic acid, designated as crotalic acid (1), and 2beta,3beta,21-trihydroxy-arbor-12-ene-29-carboxylic acid, designated as emarginellic acid (2). The

Seeds of Crotalaria retusa L. are used in popular medicine because of their pharmacological properties. The albumin fraction obtained from its seeds contains lectin, a protein known to have analgesic and anti-inflammatory properties. Thus, albumins extracted from C. retusa were investigated for

One new isoflavone, 5,7,4'-trihydroxy-2'-methoxyisoflavone (3) and seven, and four known compounds were isolated from the barks of Crotalaria pallida and the seeds of C. assamica, respectively. The known compounds, apigenin (1) and 2'-hydroxygenistein (2), isolated from C. pallida, showed

Three flavonoids, cropalliflavones A-C, including two homoisoflavonoids with rare skeletons; three previously undescribed alkaloids, usaramine-N-oxide and cropallins A-B; and sixteen known compounds, were isolated from the seeds of Crotalaria pallida Ait. The absolute configurations of

One new pterocarpanoid, crotafuran E (1), and three known compounds were isolated from the bark of Crotalaria pallida. The structure of 1 was determined by spectral methods. Two pterocarpanoids, crotafurans A (2) and B (3), previously isolated from this plant, showed significant

BACKGROUND Crotalaria pallida Ailton is a plant belonging to the Fabaceae family, popularly known as "rattle or rattlesnake" and used in traditional medicine to treat swelling of the joints and as a vermifuge. Previous pharmacological studies have also reported anti-inflammatory, antimicrobial and

Bioassay-guided fractionation of the ethanol extract of the Chinese folk medicine Crotalaria ferruginea led to the isolation of a new isoflavonoid, 4'-hydroxy-2'-methylalpinum-isoflavone (1), and eight known analogs (2-9). Their structures were elucidated by spectroscopic analysis. Compounds 1, 2,

The early changes in pulmonary artery structure and the timing and development of right ventricular hypertrophy were examined in rats after ingestion of Crotalaria spectabilis; the arteries were distended with a Micropaque--gelatin mixture. The earliest change, detected at Day 3, is the appearance
