title: [Phytochemical research of hawthorn species introduced in Lithuania].
abstract: The natural vegetable resources of Republic of Lithuania can be supplied by imported hawthorn species, subspecies and varieties, not growing naturally in the territory of country, but well growing and able to produce the crude drug with local conditions of the climate.
  
  
  OBJECTIVE
  Determinate amounts of phenolic substances (favonoid glycosides and phenolic acids) in the flowers and leaves of collected species of genus Crataegus and Crataegomespilus.
  
  
  METHODS
  Different examples of crude drug from some Lithuanian regions were extracted with 96% of ethanol and flavonoids were detected spectroscopically and with HPLC (High performance liquid chromatography).
  
  
  RESULTS
  In leaves and flowers were found different quantities of common amounts of flavonoids (1.07-2.53%) and different quantities of individual substances: flavonoids (hyperosid, vitexin-O-rhamnosid, rutin, quercitrin, quercetin, vitexin) and phenolic acids (chlorogenic and caffeic acids).
  
  
  CONCLUSIONS
  Flowers and leaves of hawthorn species, introduced in Lithuania, can be used for preparation of crude drugs procurements; the marks of phytochemical compounds of phenotypes from different genetic lines are sufficient grounds for planning of production of crude drug with special phytotherapeutic influences.
