Terpenes from Artemisia herba-alba Abou El-Hamd H. Mohamed*, Abeer M. Esmail, and Adila M. El-Saade

The green leaf volatiles 2-hexenal, (Z)-3-hexen-1-ol, 2-hexen-1-ol, 1-hexanol, and (Z)-3-hexen-1-ol acetate were present in all of the damaged plants, but in relatively lower

Chromatographic investigation of the methylene chloride/methanol extract of the aerial parts of Artemisia herba-alba afforded a new monoterpene dimer, in addition to a known

The structure of delphinifl exine was established on the basis of 1 H, 13 C, DEPT, homonuclear 1 H COSY, NOESY, HSQC, and HMBC NMR studies. Key words: Norditerpenoid

Their structures were elucidated by spectroscopic methods, including one- and two- dimensional NMR experiments (COSY, HMBC, HMQC, and ROESY). Key words: Clerodane Diterpene,

Their structures were determined by means of 1D and 2D NMR spectroscopy, including 1 H- 1 H COSY, NOESY, HSQC and HMBC experiments, which resulted in complete

The structure of 2 was as- signed to be a nor-sesquiterpene, teuhetenone A [21], on the basis of the following considerations: Its EI mass spectrum showed the molecular ion peak at

Their structures were elucidated by spectroscopic methods, including one- and two-dimensional NMR (COSY, HMQC, HMBC and ROESY). Key words: Parepigynum funingense,

Recent phytochemical studies on the ethanolic extract of Artocarpus nobilis, collected from Sri Lanka, have resulted in the isolation of two new cycloartane-type
