Investigation of Podophyllotoxin in some Plants in Lamiaceae Using HPLC: Türkiye'de Yetişen Lamiaceae Familyasındaki Bazı Türlerde Podofilotoksin'in Yüksek Basınçlı Sıvı Kromatografisi ile Tespiti

High pressure liquid chromatography has been used for the separation and the quantitation of podophyllotoxin from crude extracts of Teucri­um polium, Teucrium chamaedrys, Nepeta nuda ssp. gladulifera. Thymus capitatus, Phlomis nissolii and Salvia cilicica. The percentage of podophyllotoxin is highest in Teucrium chamaedrys (0.14%) and Nepeta nuda ssp. gladulifera (0.11%) respectively
