Popis:	Phytochemical analysis of flower buds infusion from two cultivated chemotypes of Egletes viscosa Less was accomplished. The new diterpene 12-acetoxy-7-hydroxy-3,13(14)-clerodandien-18,19:15,16-diolide, ternatin, centipedic acid and 12-acetoxy-hawtriwaic lactone were isolated from the chemotype trans-pinocarveyl acetate. Analysis of the chemotype cis-isopinocarveyl acetate yielded 12-acetoxy-7-hydroxy-3,13(14)-clerodandien-18,19:15,16 -diolide, 12-epi-bacchotricuneatin, ternatin and scopoletin. Structural elucidation of the isolated compounds was established on the basis of spectral data through the use of 1D NMR and several 2D shift correlated NMR pulse sequences and comparison with literature data.
