Geranium nepalense Sweet is a common Chinese herbal medicine and has been used as influenza, dysentery, antiphlogistic and analgesic tonic, hemostatic, stomachic, and antidiabetic drugs. The anti-inflammatory effects of G. nepalense on tetradecanoyl phorbol acetate (TPA)-induced mouse ear edema were studied in this work. The results showed that ethyl acetate fraction of the water extract of G. ...

Understanding the evaporation of pesticide droplets and wetting of leaf surfaces can increase foliar application efficiency and reduce pesticide use. Evaporation time and wetted area of single pesticide droplets on hairy and waxy geranium leaf surfaces were measured under the controlled conditions for five droplet sizes and three relative humidity levels. Stereoscopic sequential images of the d...

The commercial use of mechanical stimulation to control transplant growth is quite limited. To be commercially successful, the technique must be simple and flexible, and must not reduce plant quality. Brushing was applied to tomato (Lycopersicon esculentum) seedlings growing at a density of 2100 plants mby daily stroking with a piece of polystyrene. Ten or twenty daily strokes typically provide...

Anacardic acids, a class of secondary compounds derived from fatty acids, are found in a variety of dicotyledonous families. Pest resistance (e.g., spider mites and aphids) in Pelargonium xhortorum (geranium) is associated with high levels (approximately 81%) of unsaturated 22:1 omega 5 and 24:1 omega 5 anacardic acids in the glandular trichome exudate. A single dominant locus controls the prod...

Strong radical-scavenging activity of Geranium macrorrhizum extracts isolated by using various solvent systems has been reported previously. This study aimed at expanding the knowledge on the bioactivities of antioxidatively active G. macrorrhizum butanol fraction, which was isolated from ethanolic extract (EB), and water fraction, which was isolated from water extract (WW) by measuring their s...

A 68-year-old male retired non-atopic school librarian was referred for suspected plant contact dermatitis. The patient had taken up gardening as a hobby when he retired from work: mowing the lawn, cutting hedges and weeding in his garden. For 6–10 years, he had suffered from transient dermatitis on his eyelids, which he attributed to a habit of wiping his eyelids with his hands during gardenin...
