Studies
• Antimicrobial / Antifungal: (1) The study screened plants extracts - including Bixa orellana – for antimicrobial activity and MIC. B orellana showed low MIC against against E coli and a better MIC against B cereus. Results showed that Bixa orellana, Justicia secunda and Piper pulchrum could be potential sources of new antimicrobial agents. (2) Study of organic extract of BO showed to possess a narrow spectrum of antimicrobial activity, effective only against Gram+ bacteria used in the study.
• Antibacterial / Antioxidant / Antidiarrheal / Neuropharmacolic / Anticonvulsant/ Gastrointestinal Motility Effect: Preliminary pharmacologic studies on the methanol extracts of BO leaves showed statistical decrease in locomotor activity, anticonvulsant effect, analgesic and antidiarrheal effect and a delay i gastrointestinal motility. It also showed radical scavenging properties and antibacterial activity against agents of diarrhea and dysentery.
• Hypoglycemic / Antidiabetic: (1) Study of BO oil seed suspension of the red seed coat showed it to be a potent hypoglycemic agent. Extract study showed hypoglycemia in both normal and streptozotocin diabetic dogs. (2) Annatto extract was found to decrease blood glucose in fasting normoglycemic and streptozocin-induced diabetic dogs. The activity was attributed to the stimulation of peripheral utilization of glucose.
• Milk-based pigment: Study showed B orellana seeds can be used as a pigment in making milk-based paint.
