Abstract
The composition and amount of hydrophilic and lipophilic extractives in knots and stemwood of eight Turkish and one Pakistani tree species were analysed. Lignans were the main polyphenols in most studied species and pinosylvins in the pines. The two studied juniper species contained no or only little lignans. Most species also contained juvabiones or phenolic diterpenoids. Both polyphenols and lipophilic extractives were more abundant in the knots than in the stemwood.
Zusammenfassung
Die Zusammensetzung und die Menge der hydrophilen und lipophilen Extraktstoffe in Ästen und im Stammholz von acht türkischen und einer pakistanischen Baumart wurden untersucht. In den meisten der untersuchten Baumarten waren Lignane die vorherrschenden Polyphenole; in den Kiefern waren es Pinosylvine. Die zwei untersuchten Wacholderarten enthielten keine bzw. nur wenig Lignane. Die meisten Arten enthielten auch Juvabione oder phenolische Diterpenoide. Astholz enthielt mehr Polyphenole und lipophile Extraktstoffe als Stammholz.
