A new acylated luteolin glycoside from Curcuma Longa L. and free radical scavenging potential of its extracts
The ethanol and water extracts of turmeric (Curcuma longa L.) displayed free radical scavenging activity. Chemical investigation of the ethanolic extract led to the isolation of a new acylated luteolin glucoside, luteolin-7-O-(6"-p-hydroxybenzoyl-b-D-glucopyranoside) (compound 1), together with the known flavonoids: luteolin 7-O-b-D-glucopyranoside (compound 2), apigenin-7-O-b-D-glucopyranoside (compound 3),...

Studies on the molecular mechanism of cholesterol reduction by Fraxinus angustifolia, Peumus boldus, Cynara cardunculus and Pterospartum tridentatum infusions
Infusions of Peumus boldus Molina, Cynara cardunculus L., Fraxinus angustifolia Vahl and Pterospartum tridentatum (L.) Willk are recommended in Portugal to reduce serum cholesterol levels, among other effects. Volunteers drinking these infusions showed plasma total cholesterol reductions of 14% with Pterospartum boldus and 22% with P. tridentatum. C. cardunculus mixed with F. angustifolia or P. tridentatum resulted in...

Central nervous system depressant and analgesic activities of Scutia myrtina in experimental animal model
The purpose of this study is to investigate the central nervous system (CNS) depressant and analgesic activities of the ethanol extract of Scutia myrtina (EESM) (Family: Rhamnaceae) in Swiss albino mice. To evaluate the CNS depressant activity by using the methods such as general behavior, exploratory behavior, muscle relaxant activity and phenobarbitone sodium-induced sleeping time were studied....

Changes in Kaempferol content of Chicory (Cichorium intybus L.) under water deficit stresses and planting densities
To investigate the beneficial impacts of plant density on drought resistance of chicory (Cichorium intybus L. var. ‘Qazvin’), we conducted an experiment in the field by measuring certain features essentially related to yield characters. Our objective in this study was to assess the interactive effects of various plant densities (6, 9, 12 and 15 plants/m2) and watering limitation. In the latter, water supply...

Proteomic analysis of acute kidney allograft rejection in rat
Kidney transplantation to treat end-stage renal disease has evolved rapidly from the first successful transplantations to the current widespread use of grafts from both cadaveric and living donors. But acute rejection is still a strong risk factor for chronic rejection in recipients of renal grafts. To investigate possible mechanisms, we describe a comparison between different proteins expression profile of acute...

Rapid in vitro multiplication and biological potentialities of Sericostoma pauciflorum stocks ex Wight
In the present study, an efficient in vitro plant regeneration protocol for Sericostoma pauciflorum stocks ex Wight, which is known for hypoglycemic efficacy, was achieved. Callus cultures from nodal explants were raised on Murashige and Skoog’s (MS) medium with Indole acetic acid (IAA, 0.5 to 2 mg/l) and 2, 4-dichlorophenoxyacetic acid (2, 4-D, 0.5 to 2 mg/l). Shoot regeneration occurred from callus cultures...

Antidiabetic and genotoxic effects on Wistar rats treated with aqueous extract from Chrysobalanus icaco L.
Chrysobalanus icaco L. is a medicinal plant, used to treat diabetes and dyslipidemia in Brazil. The biological effects may vary depending on the source of plant. Experiments were performed to assess these effects from plants collected in the field and those obtained from dried herbs market. Glycemia, cholesterol and triglycerides serum concentrations were measured in healthy and diabetic rats treated with aqueous...

Establishment of hairy root culture and production of secondary metabolites in Coleus (Coleus forskohlii)
Production of hairy roots through transformation and in vitro culture was attempted in Coleus using MTCC 2364 strain of Agrobacterium rhizogenes. Nodal stem part and mature leaf were used as explants. The nodal stem part responded with huge amount of root production. From the nodal part first 3 to 4cm long shoot emergence took place and after that within 12 days roots started emerging from base of node. If the shoot...

In vitro antioxidant, total phenolic, membrane stabilizing and antimicrobial activity of Allamanda cathartica L.: A medicinal plant of Bangladesh
The methanol extract of the leaf of Allamanda cathartica L. as well as its hexane, carbon tetrachloride, chloroform and aqueous soluble partitionates were subjected to screening for antioxidant, membrane stabilizing and antimicrobial activities. The antioxidant potential was evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and Folin-Ciocalteau reagents using butylated hydroxytolune (BHT) and ascorbic acid as standards....

Antinociceptive effects of Maytenus imbricata Mart. ex. Reissek (Celastraceae) root extract and its tingenone constituent
Plants belonging to the genus Maytenus (Celastraceae) are routinely used in folk medicine for the treatment of pain and inflammatory diseases. The aim of this study was to assess the in vivo anti-inflammatory and anti-nociceptive effects of the root extracts and tingenone, a natural triterpene, from Maytenus imbricata Mart. ex. Reissek. Oral pre-treatment with methanol extract (ME), ethyl acetate extract (EAE) (both 100...

Chemical composition of essential oil from the fiddleheads of Pteridium aquilinum L. Kuhn found in Ogoni
The present study was designed to determine the chemical composition of the essential oil from the fiddleheads of Pteridium aquilinum L. Kuhn, so as to enable more effective utilization of such bioactive ingredients. Gas chromatography analysis of the essential oil distillate revealed the presence of 40 compounds that consisted mainly of alkanes (86.60%), monoterpenes (3.20%) and sesquiterpenes (2.40%). The most...

Using toasted barley in sesame oil mixture for non-surgical necrosis debridement of experimental burns in rat
Burns are the most damaging kind of injuries, major global public health crisis and the fourth most common types of trauma. Decision making in the treatment of burns remains a challenge despite existence of improved assessment techniques and treatment procedures. One of the most complications in healing of burn tissues is necrosis. Several medicinal plants were used to treat skin disorders as burn wounds and necrosis so...
