The title compound, C34H36O9·CH3OH, is a diterpenoid isolated from the roots of Caesalpinia pulcherrima (L.) Swartz. The three trans-fused six-membered rings are in chair, chair and half-chair conformations. The mean plane of this fused-ring system makes dihedral angles of 67.95 (15) and 83.72 (14)° with the two phenyl rings of the benzo-yloxy groups. An intra-molecular C-H⋯O hydrogen bond is o...

The aim of this study was to search for new antiviral agents from Chinese herbal medicine. Pure flavonoids and aqueous extracts of Caesalpinia pulcherrima Swartz were used in experiments to test their influence on a series of viruses, namely herpesviruses (HSV-1, HSV-2) and adenoviruses (ADV-3, ADV-8, ADV-11). The EC50 was defined as the concentration required to achieve 50% protection against ...

In Indonesia, Caesalpinia pulcherrima (L) Swartz is widely grown as an ornamental, whereas it is used as a medicinal herb in Mexico as an alternative treatment for dental and oral infections. At present, only fruit and root parts of the plant are used. The aim of this study was is evaluate the anti-microbial activity of ethanol extract of fruit, leaves, flowers and stems against microbes that c...

OBJECTIVE To determine the larvicidal efficacy of different solvent leaf extract of Ervatamia coronaria and Caesalpinia pulcherrima against Anopheles subpictus and Culex tritaeniorhynchus. MATERIALS AND METHODS Twenty five early third instar larvae of Anopheles subpictus and Culex tritaeniorhynchus were exposed to various concentrations and were assayed in the laboratory. The larval mortality...

Thirteen polyphenolics were isolated from fresh pods of Caesalpinia pulcherrima using various methods of column chromatography. The structures of these polyphenolics were elucidated as gallic acid (1), methyl gallate (2), 6-O-galloyl-d-glucoside (3), methyl 6-O-galloyl-β-d-glucoside (4), methyl 3,6-di-O-galloyl-α-d-glucopyranoside (5), gentisic acid 5-O-α-d-(6'-O-galloyl)glucopyranoside (6), gu...

The screening of lesser-known underutilized seeds as source of food has been a way of finding solution to food insecurity in developing nations. In this regard, oil as a class of food was extracted from the seeds of Diospyros mespiliformis  (4.72 ± 0.2%), Albizia lebbeck  (6.40 ± 0.60%), and Caesalpinia pulcherrima  (7.2 ± 0.30%). The oils were finally analyzed for their fatty acid composition,...

this study examines the controlled release behavior of both water-soluble (acetaminophen, caffeine, theophylline and salicylic acid) and water insoluble (indomethacin) drugs derived from caesalpinia pulcherrima seed gum isolated from caesalpinia pulcherrima kernel powder. it further investigates the effect of incorporating diluents such as microcrystalline cellulose and lactose on caffeine rele...
