• Antimicrobial: (1) Antimicrobial
activity of Caesalpinia pulcherrima, Euphorbia hirta and Asystasia gangeticum:
Studies on the ethanolic extracts of the dry fruits of C. pulcherrima
showed a broad spectrum of antimicrobial activity against E. coli (enteropathogen),
Proteus vulgaris, Pseudomonas aeruginosa and Staphylococcus aureus. (2) Study on the antibacterial effects of selected Indian medicinal plants was evaluated on strains of B cereus, S aureus, E aerogenes, E coli and K pneumonia. The most active antibacterial plant was Caesalpinia pucherrima.
• Antiviral: In vitro antiviral activities of Caesalpinia
pulcherrima and its related flavonoids: A study showed a potential
for use in the treatment of infection caused by two viruses: herpesviruses
and adenoviruses. The aqueous extract of CP and its flavonoid quercetin showed a broad spectrum of antiviral activity.
• Anti-inflammatory: The study showed anti-inflammatory activity attributed to flavonoids. Results support the
use of Caesalpinia pulcherrima for the treatment of inflammatory conditions
in traditional medicine.
• Furanoid Diterpenes / Antibacterial /
Antifungal : Study
isolated four new cassane-type furanoditerpenoids from the leaves of
CP. Antimicrobial testing showed activity against bacteria (S aureus,
E coli, P aeruginosa and B subtilis) and fungia ( C albicans and T mentagrophytes).
Nutrient studies of CP Seeds: Study
suggests C pulcherrima could be a good source of low cost plant protein,
a good source of iron and calcium; the whole seeds more nutrient-rich
than the seed nuts.
Flavonoids / Antiinflammatory: Study
isolated five flavonoids from CP which significantly and dose-dependently
inhibited inflammatory mediators, NO, cytokines (TNF and IL-12).
of methanol extract of 9 Indian medicinal plants showed C pulcherrima
with good antifungal activity against C albicans.
• Antioxidant / Cytotoxic: Study on the methanolic and aqueous extracts of C pulcherrima showed both exhibiting strong antioxidant activity. Testing for cytotoxicity, the aqueous extract was relatively toxic. Results of antioxidant and cytotoxic activities were attributed total phenolic content of the wood.
• Analgesic: Study on the chloroform extract of Caesalpinia pulcherrima showed significant analgesic activity through a peripheral mechanism.
• Drug Release Study / Excipient / Seed Polysaccharide: Caesalpinia pulcherrima seed polysaccharide can be used for the controlled release of both water-soluble and water insoluble drugs.
• Anthelmintic: Study evaluated the in vitro anthelmintic potency of various extracts of CP flowers against Indian earthworms Pheretima posthuma. Results showed all the extracts exhibited anthelmintic activity, and the aqueous extract took the least time to cause earthworm paralysis.
• Anti-Inflammatory / Anti-Ulcer: Ethanolic and aqueous extracts of aerial parts of C. pulcherrima exhhibited significant anti-inflammatory activity in the cotton pellet granuloma model and significant anti-ulcer activities in the pylorus ligation- and aspirin-induced ulcer models.
• Antimicrobial / Antioxidant: Study investigated the antimicrobial and antioxidant activities of seeds and fruit rind of C. pulcherrima. Among the solvents, the methanol extract showed the best antibacterial and antioxidant activities.
• Seed Mucilage / Binder: Study isolated a water soluble mucilage from the seeds of C. pulcherrima. It was found to possess excellent binging property to serve as potential binder in conventional tablet formulation.
