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...

OBJECTIVES Findings natural products with antioxidant and antiapoptotic properties has been one of the interesting challenges in the search for the treatment of neurodegenerative diseases including ischemic stroke. Serum/glucose deprivation (SGD) has been used as a model for the understanding of the molecular mechanisms of neuronal damage during ischemia in vitro and for the expansion of neurop...

BACKGROUND Hibiscus sabdariffa is used regularly in folk medicine to treat various conditions. METHODS The study was a double blind, placebo controlled, randomized trial. Sixty subjects with serum LDL values in the range of 130-190 mg/dl and with no history of coronary heart disease were randomized into experimental and placebo groups. The experimental group received 1 gm of the extract for 9...

This study aimed to determine the exact cinnamon concentration in manufacture of rosella flower petal syrup based on its physical and chemical properties. A completely randomized experimental design with six levels concentration, i.e., 0, 1, 3, 5, 7, 9 g, respectively, replicated four times was applied this research. Analyses were performed both concentrated diluted forms syrup. Parameters obse...

A solar cell was manufactured from local materials and dyed using dyes extracted different organic plants. The glass slides were coated with a nano-porous layer of Titanium Oxide infused two types acids, Nitric acid Acetic acid. Pomegranate, Hibiscus, Blackberry Blue Flowers. They then tested comparison made for the amount voltage they generate when exposed to sunlight. Hibiscus sabdariffa extr...
