Study reported on the extraction of indigo from CG fruit and application of the crude extract on cotton fabric. Thin layer chromatography yielded three pigments: violet, blue, and pink with Rf values of 0.88, 0.57, and 0.25 respectively. The % purity of the indigo dye was 26.46%. Dyeing of cotton fabric with crude dye powder gave comparable fastness properties vis-a-vis synthetic indigo. (31)
Quorum Sensing against Enterobacter aerogens: Bacteria make use of cell-cell signaling system known as Quorum Sensing (QS). Study evaluated the anti-quorum sensing efficacy of Couroupita guainensis against Enterobacter aerogenes, estimated with reference to QS Biomonitoring strain Chromobacterium violaceum and Pseudomonas aeruginosa. Docking studies revealed the necessary crucial hydrogen bond interactions with critical amino acids and that the compound CID_641785 with the highest binding score might be an effective inhibitor of Enterobacter aerogenes pathogenesis. (32)
Anxiolytic / Flowers: Study evaluated aqueous and methanol extracts of CG for anxiolytic activity in Swiss albino mice using elevated plus maze (EPM), light and dark (LD), and open field test (OFT) models. Both extracts of CG at a dose of 500 mg/kg showed significant anxiolytic activity in the three models in mice. (33)
Antiulcer / Leaves: Study evaluated the antiulcer activity of ethanolic extract of Couroupita guianensis leaves in pylorus ligation and ethanol induced ulcer models in experimental rats. Results showed a significant inhibition of gastric lesions induced by pylorus ligation induced ulcer and ethanol induced gastric ulcer, with significant (p<0.05) reduction in gastric volume, free acidity, and ulcer index as compared to control. The antiulcerogenic property may be due to its antisecretory activity. (34)
Isatin / Antioxidant / Anticancer / Flowers: Isatin (1H-indole-2,3-dione) has been isolated from the flowers of Couroupita guianensis. Isatin derivatives are known to have cytotoxicity against human carcinoma cell lines with a potential as chemotherapeutic agent against cancer. In this study, isatin from the active fraction showed antioxidant activity with EC50 value of 72.80 µg/ml and exhibited cytotoxicity against human promyelocytic leukemia HL60 cells in dose-dependent manner with CC50 value of 2.94 µg/ml. The isatin-treated cells underwent apoptosis and DNA fragmentation. (35)
