Volatile Constituents of Hops

Volatile Constituents of Matricaria chamomilla

      The volatile oil obtained by hydrodistillation of the aerial parts of Matricaria chamomilla L. (Asteraceae) growing in Botanical Garden, Isfahan University of Medical Sciences, Iran, was investigated by gas chromatography (GC) and GC/ mass spectrometery (MS). Sixty-three components were characterized, representing 86.21% of the total oil components detected. α-B...

Lupulon and Humulon-antibiotic Constituents of Hops.

Volatile constituents of Jasminum humile L.

The essential oil was obtained by hexan. The sample oil, which was light yellow in color, was dried over anhydrous sodium sulfate and stored under nitrogen in a sealed vial until required. The oil obtained was analyzed by GC-MS and GC/MS. The components of the oil were identified by comparison of their mass spectra to those of a computer library or with authentic compounds and confirmed by comp...

Volatile Constituents of Propolis

Propolis (bee glue) is a resinous hive product, collected by bees. It possesses versatile biological activity antibacterial, antiviral, fungicidal, anti­ ulcer, immunostimulating, hypotensive, cytostatic, etc. [1]. The chemical com position of propolis ap­ peared to be very complex at least 156 propolis constituents have been identified so far [2,3]. M ost im portant constituents of propolis ap...
