摘要: Abstract A new natural product has been obtained from the roots of “Carrizo citrange” rootstocks (Citrus sinensis × Citrus trifoliata) infected by nematode Tylenchulus semipenetrans, and its structure identified as diterpene carnosic acid-11-methylether (1) on basis spectroscopic data chemical means. The known compounds β-sitosterol (sterol), lupeol (triterpene), 5-hydroxy-3,7,3′,4′-tretramethoxy-flavone 5-hydroxy-6,7,3′,4′-tetramethoxy-flavone (flavones), citracridone-I (alkaloid) xanthyletin, nordentatin poncitrin (chromenecoumarins), were isolated same source.
