Introduction. Purple passionflower (Passiflora incarnata) is introduced in the Russian Federation and grows along the Black Sea coast of the Caucasus. Purple passionflower herb is a constituent of sedative drugs, and it is also used in homeopathy. The plant has a complex composition of biologically active substances. Flavonoids are one of the groups that determine its pharmacological activity. Objective: to investigate the composition and content of flavonoids in purple passionflower herb. Material and methods. The investigation object is dried purple passionflower herb. Tests used an Agilent 1100 liquid chromatograph with a diode-array detector. Results. HPLC-UV analysis established that the purple passionflower contained 20 flavonoid compounds. There were 8 flavonoids: isovitexin, vitexin, rutin, luteolin, hyperoside, kaempferol, kaemferitrin, orientin, and isoorientin. The content of vitexin was 0.202±0.001%; the amount of flavonoids calculated with reference to vitexin was 0.891±0.015%. Conclusion. The content and composition of flavonoids in purple passionflower were established by a HPLC-UV method. The findings can be used to improve regulatory documentation for purple passionflower herb.
