S. Bokstaller et Pc. Schmidt, A COMPARATIVE-STUDY ON THE CONTENT OF PASSIONFLOWER FLAVONOIDS AND SESQUITERPENES FROM VALERIAN ROOTS EXTRACTS IN PHARMACEUTICAL PREPARATIONS BY HPLC, Die Pharmazie, 52(7), 1997, pp. 552-557
This comparative study presents the determination of flavonoids from P
assiflora incarnata and sesquiterpenes from Valeriana officinalis in p
harmaceutical preparations, Several liquid and solid commercial prepar
ations containing extracts of these and possibly one other plant were
investigated, The quantitative determination of flavonoids and sesquit
erpenes was performed by two HPLC-methods, suitable for routine analys
is, The determination of liquid formulations detected 0.31-5.81 mg fla
vonoids and 0.03-0.86 mg sesquiterpenes per 1 g of the sample while th
e solid dosage forms contained 0.64-5.36 mg flavonoids and 0.16-1.85 m
g sesquiterpenes per unit.
