the essential oils of peucedanum ruthenicum m. bieb. (umbelliferae) leaves, flowers and fruits were prepared by hydrodistillation and analyzed by gc and gc-ms and the composition of the three essential oils were compared. thirty-three, thirty-seven and thirty-one compounds were identified in leaves, flowers and fruits essential oils representing 89.13%, 88.66% and 76.45% of total oils respectiv...

ITRIC oxide (NO) increases X-radiation damage approximately the same Namount as equal quantities of oxygen in Shigella flexneri ( HOWARD-FLANDERS 1957), Vicia faba (KIHLMAN 1958), ascites tumor cells (GRAY, GREEN, and HAWES 1958), and barley seeds with greater than 12 percent water content (SPARRMAN, EHRENBERG, and EHRENBERG 1959). These observations, as well as later comparisons of these gases...

Spiranthera odoratissima A. St. Hil. (manacá) is used in folk medicine to treat renal and hepatic diseases, stomachache, headaches and rheumatism. A central nervous system (CNS) depressant effect of the hexane fraction from the ethanolic extract of this plant has been described. β-caryophyllene, the main component of this essential oil, is a sesquiterpene compound with anti-inflammatory propert...

This study aimed to identify the chemical composition (ash, cellulose, total chlorophylls, carotenoid, and essential oil (EO) content), antioxidant activity, mineral of lemon balm (Melissa officinalis L) obtained from Bulgaria. The EO was analyzed using gas chromatography-mass spectrometry (GC-MS). major constituents were caryophyllene oxide (33.99%), n-hexadecanoic acid (14.28%), α-citral (6.6...

Abstract In the current study, we used high-performance liquid chromatography (HPLC) and gas chromatography–mass spectrometry (GC–MS) to investigate analyze methanolic extract of Salvia rosmarinus leaves. HPLC analysis showed that revealed a diverse array polyphenolic compounds, including apigenin, catechin, chlorogenic acid, cinnamic caffeic coumaric daidzein, ellagic ferulic gallic hesperetin...

Plant Based Natural Products (PBNPs) have contributed to the development of drugs for diverse indications. Worldwide interest in use PBNPs has been growing, and its beneficial effects being rediscovered drug leads. Literature survey on indigenous traditional knowledge bestows ethnopharmacological potentials PBNPs, inspired research design discovery; provide a baseline novel leads against variou...

Wedelia trilobata is an invasive weed of the family Asteraceae.Objective study was to find out impact essential oil on germination and seedling growth cowpea. Different concentrations oil(200, 400, 600, 800 1000ppm) were used,a controlwas kept without oil. Cowpea seeds sown in these petriplates,at end test period all parameters measured. All showed that treatment had no negative germination. Wh...

BACKGROUND This study examined long-term outcome from severe forebrain ischemia in the rat, as a function of anesthetic given during the ischemic injury. METHODS Rats were subjected to 10 min of near-complete forebrain ischemia while anesthetized with either 1.4% isoflurane or 70% nitrous oxide-fentanyl. Neurologic and histologic outcomes were measured at 5 days, 3 weeks, or 3 months after is...
