The inhibitory effects of essential oils including clove, lavender and geranium extracted from Eugenia caryophyllata, Lavandula officinalis and Pelargonium graveolens on multidrug resistant isolates of Pseudomonas aeruginosa were investigated. The main constituents of clove, lavander and geranium oil were eugenol (80-90%), 1,8-cineol (13%) and citronellol (45%) respectively. Clove had the most ...

1,3-Dimethylamylamine (1,3-DMAA) is a stimulant commercially sold in a variety of dietary supplements as a chemical species derived from geranium plants (Pelargonium graveolens). Whether 1,3-DMAA naturally occurs in geranium plants or other dietary ingredients, it has important regulatory and commercial ramifications. However, the analysis of 1,3-DMAA in geranium plants is not trivial due to lo...

The study of the chemical constituents of the whole plant of Geranium wallichianum (Geraniaceae) has resulted in the isolation and characterization of six compounds. These six compounds were identified as ursolic acid (1), β-sitosterol (2), stigmasterol (3), β-sitosterol galactoside (4), herniarin (5), and 2,4,6-trihydroxyethylbenzoate (6) which were isolated for the first time from Geranium wa...

To obtain experimental evidence on the therapeutic efficacy of essential oils in aromatherapy for inflammatory diseases, we examined the effects of geranium oil on carrageenan-induced and collagen II-induced inflammation in mice, to assess acute and chronic anti-inflammatory activities of the oil. Single intraperitoneal injection of 5 mu L of geranium oil clearly suppressed the carrageenan-indu...

Several diseases of geraniums (Pelargonium species) are caused by viruses. The economic losses caused by these diseases are difficult to assess since infected plants are often symptomless and because both the cultivar and the environment in which the plants are growing can greatly influence the severity of the symptoms. The problem is compounded by the diverse sources of stock plants and the fa...

BACKGROUND AND AIMS Lomatium dissectum (Apiaceae) is a perennial, herbaceous plant of wide distribution in Western North America. At the time of dispersal, L. dissectum seeds are dormant and have under-developed embryos. The aims of this work were to determine the requirements for dormancy break and germination, to characterize the type of seed dormancy, and to determine the effect of dehydrati...
