The concentration of indoleacetic acid (IAA) in plant tissues is regulated, in part, by its rate of decarboxylation. However, the commonly used in vitro assays for IAA oxidase may not accurately reflect total in vivo decarboxylation rates. A method for measuring in vivo decarboxylation was utilized in which (14)CO(2) is collected following uptake of [1-(14)C]IAA by excised tissue sections. Afte...

Water extract of the leaves of Coleus aromaticus  Benth. Was tested for its antiurolithiatic activity against calcium oxalate stones in male albino rats. Calcium oxalate stones were induced by feeding 3% w/w sodium oxalate along with normal feed. The water extract of coleus aromaticus (0.5 g/kg and 1.0 g/kg, once, orally for 30 days) was found to be effective in reducing deposition of calcium o...

Forskolin is a unique structurally complex labdane-type diterpenoid used in the treatment of glaucoma and heart failure based on its activity as a cyclic AMP booster. Commercial production of forskolin relies exclusively on extraction from its only known natural source, the plant Coleus forskohlii, in which forskolin accumulates in the root cork. Here, we report the discovery of five cytochrome...

Water extract of the leaves of Coleus Aromaticus Benth was tested for its diuretic activity in male albino rats. The study was carried out on normal rats using furosemide as a standard reference drug. Rats were treated with furosemide (4 mg/kg. p.o) and Coleus aromaticus (0.5 g/kg and 1.0 g/kg, p/o). Urine was collected and its volume was recorded. Urinary levels of sodium, potassium and chlori...

Rotylenchulus macrodoratus completed its embryogenic development in about 16-19 days at 18-32 C. On olive seedlings the life-cycle from egg to egg was completed in 45-55 days. The first molt occurred in the egg while the other three were superimposed, with retention of successive larval cuticles. Only immature vermiform and swollen egg-laying females were found attached to olive roots. Eggs are...
