   • According to Solomon S (2015)

     Excerpt The flowers of Tabebuia rosea was tested for its anti-cancer activity against liver cancer HePG2 cell line by MTT assay. The present study has been performed experimentally by in vitro method to examine the anti-cancer activity of flowers of Tabebuia rosea.

   • According to HEMAMALINI K (2011)

     Excerpt The present study was conducted to evaluate the hepatoprotective activity of methanolic extracts of Tabebuia rosea & Solanum pubescens against paracetamol induced liver damage in rats. It was concluded from the result that the methanolic extract of T rosea & S pubescens possesses hepatoprotective activity against paracetamol induced hepatotoxicity in rats,.

   • According to Hemamalini K (2012)

     Excerpt The purpose of this study was to investigate the experimentally possible antitumor effect & antioxidant role of methanolic extract of Tabebuia rosea leaves against Dalton’s ascetic lymphoma (DAL) induced Swiss albino mice. The methanolic extract of Tabebuia rosea (METR) was administered at the doses of 100mg/kg, 200mg/kg in mice for 14 days after 24hours of DAL inoculation.

   • According to Ramalakshmi S (2011)

     Excerpt Tabebuia rosea is one of the medicinally important plants belonging to the family Bignoniaceae. Traditionally, taheebo has been used for treating ulcers, syphilis, gastrointestinal problems, candidiasis, cancer, diabetes, prostatitis, constipation, & allergies.

   • According to Pagaza-Straffon EC (2021)

     Excerpt Tabebuia rosea has been reported to have anti-cancer, antioxidant, & hypoglycemic activities, & other species of the same genus have anti-obesity effect.

   • According to Sathya M (2008)

     Excerpt In vitro antibacterial studies on the ethanolic leaf extracts were carried out on ten medically important bacterial strains, including Salmonella typhimurium, Pseudomonas aeruginosa, Klebsiella pneumonia, Escherichia coli, Pseudomonas sp. Staphylococcus epidermis, Micrococcus luteus, Staphylococcus aureus, Streptococcus sp.

   • According to Franco Ospina LA (2013)

     Excerpt Both Tabebuia species revealed significant antibacterial activity against Staphylococcus aureus ATCC 25923. Results: ethanol extracts from TR & TO inner bark, as well as some of their fractions showed significant antiinflammatory & antioxidant activity, being generally Tabebuia rosea more active as antiinflammatory.

   • According to Sobiyana P (2019)

     Excerpt This paper reports the antioxidative & antimicrobial exercises of oil ether Tabebuia rosea & Tabebuia argentea extricates. Oil ether concentrates of Tabebuia rosea & Tabebuia argentea blossoms were assessed for their free radical searching action utilizing the DPPH radical test.

   • According to Solomon S (2018)

     Excerpt The present study was carried out to investigate the antimicrobial effect of the sample isolated from the ethylacetate fraction of flowers of Tabebuia rosea. The anti-bacterial activity of the compound isolated from ethyl acetate fraction is almost comparable with standard solvent control Chloramphenicol.
