Sparteine, Phlogacanthosides A,B and C are present as bioactive compounds in this plant. Treatment with the leaves and flowers extract for 21 days normalized the reduced levels of Alanine transaminase (SGPT), aspartate transaminase (SGOT), alkaline phosphate (ALP), cholesterol and triglyceride in STZ (streptozotocin) treated mice.
