The volatile constituents of the aerial parts of vervain (Verbena officinalis L.) cultivated locally were investigated. Analysis of the volatile fraction by GC and GC-MS is described. Compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).

The response of the two most abundant cockchafer species in central Europe, Melolontha hippocastani and M. melolontha, towards phenol, mixtures of phenol with the leaf alcohol (Z)-3-hexen-1-ol and the known cockchafer pheromones, 1,4-benzoquinone (M. hippocastani) and toluquinone (M. melolontha), was investigated in the field. During the swarming period at dusk, phenol attracted males of both s...

To elucidate whether any relationship exists between ovarian blood flow and ovulation rate, the effects on these parameters were examined in equine chorionic gonadotrophin/human chorionic gonadotrophin (eCG/HCG) (15I U/15I U) primed rats after bilateral ligation and severance of either the ovarian branch of the uterine artery and vein (UL), the ovarian artery and vein (OL) or both sites (UL+OL)...

A new farnane-type pentacyclic triterpene, farnan-2-one-3 beta-ol (mimusopfarnanol), was isolated from the stem bark of Mimusops elengi L. along with the known triterpenoids, farnan-3-one, olean-18-en-2-one-3-ol and lup-20 (29)-en-3 beta-ol and their structures have been characterized on the basis of spectral data analyses and chemical reactions.

To examine the possible age-related blood pressure (BP) deregulation in response to central hypervolemia, we measured spontaneous baroreflex sensitivity (SBRS), carotid arterial compliance (CC), and R-R interval coefficient of variation (RRICV) during basal and thermoneutral resting head-out-of-water immersion (HOWI) in 7 young (YG = 24.0 +/- 0.8 years) and 6 middle-aged/older (OL = 59.3 +/- 1....

1. The metabolism of [4-(14)C]pregnenolone to androst-16-enes has been studied in short-term incubations of boar testis tissue. With fresh tissue androsta-5,16-dien-3beta-ol (8%) and 5alpha-androst-16-en-3beta-ol (2%) were formed. Tissue that had been stored at -20 degrees C was still capable of metabolizing pregnenolone to androsta-5,16-dien-3beta-ol. 2. NADPH was essential for the formation o...

Five new labdane diterpenes (1-5) together with seven known diterpenes have been isolated from a methanol extract of the aerial parts of Aster oharai. Five new structures were determined as 7alpha-hydroperoxylabda-8(17),14-dien-13(R)-ol-4-O-acetyl-alpha-L-6-deoxyidopyranoside (1), 7alpha-hydroperoxylabda-8,14-dien-13(R)-ol-4-O-acetyl-alpha-L-6-deoxyidopyranoside (2), labda-7,14-dien-13(R)-ol-4-...

INTRODUCTION Oral leukoplakia (OL) is the most common potentially malignant lesion of the oral cavity. AIM The purpose of the study was clinical and epidemiological analysis of patients with OL diagnosed and treated in the Department of Maxillofacial and Oral Surgery, Medical University of Gdansk, comparison of effectiveness of treatment methods, defining whether van der Waal level of OL infl...

Neher and Wettstein (1) have recently published the details of a paper chromatographic method for the separation of weakly polar steroids, with a heptane-phenyl Cellosolve solvent system. Savard (2) has described the separation of 17-ketosteroids on paper with ligroin as the mobile phase and propylene glycol as the stationary phase. Starting from the basic work of these authors, a method has be...
