Pyrolysis-gas chromatography in the presence of tetramethylammonium hydroxide (TMAH) was applied to the determination of the ratio of the abundances of the syringyl beta-aryl ether subunits to those of the guaiacyl equivalents (S/G) in lignin. Diazomethane-methylated kenafs (Hibiscus cannabinus and Hibiscus sabdariffa) and beech (Fagus crenata) in situ lignins were employed. Relative abundances...

Germplasm identification and characterization is an important link between the conservation and utilization of plant genetic resources. Traditionally, species or cultivars identification has relied on morphological characters like growth habit or floral morphology like flower colour and other characteristics of the plant. Studies were undertaken for identification and determination of genetic v...

AIM To determine the androgenic effects of Basella alba and Hibiscus macranthus extracts in the rat and the bull, and to develop a novel in vitro test system using Leydig cells from bull testes. METHODS The effect of methanol extracts from both plants on testosterone production in isolated Leydig cells from the rat and the bull was analyzed using 125I-radioimmunoassay (125I-RIA). Rat Leydig c...

CONFLICT OF INTEREST none declared. OBJECTIVE We aimed to evaluate the effects of Hibiscus sabdariffa (HS) calices on controlling dyslipidemia in obese adolescents. METHODOLOGY In this triple blind randomized placebo-controlled clinical trial which was registered in the Iranian registry for clinical trials (IRCT201109122306N2), 90 obese adolescents aged 12-18 years with documented dyslipide...

Hibiscus rosasinensis L. (Malvaceae) is used in folk medicine for the treatment of pain and various inflammatory conditions such as the inflammation of oral mucosa, blenorrhoea, and asthmatic bronchitis. In the present study the methanolic extract of Hibiscus rosasinensis leaves ( 250 and 500 mg/kg body weight orally) was studied for anti-nociceptive and anti-inflammatory activities in various ...

Due to the higher resolution, confocal microscopy (CLSM) can be applied to refine the origin of tiny structures of the autofluorescent exoskeletons of microarthropods (mites in particular) which are hard to visualize using traditional differential interference contract light microscopy (DIC LM) and phase contrast light microscopy (PC LM). Three-dimensional (3D) reconstructions of the prodorsal ...

Hibiscus hispidissimus Griff. is used in tribal medicine of Kerala, the southern most state of India, to treat liver diseases. In the present study, the effect of the ethanolic extract of Hibiscus hispidissimus whole plant on paracetamol (PCM)-induced and carbon tetrachloride (CCl4)-induced liver damage in healthy Wistar albino rats was studied. The results showed that significant hepatoprotect...

In nature Sclerotium Rolfsii attacks the hosts usually at their foot. In a case was observed by the author a Hibiscus plant attacked at about a meter above the ground. By what means the pathogene reached at that height is still unknown. It may be possible that the infection has been caused by basidiospores transported by flow of air. It is therefore interesting to know the relation of germinati...
