A bioactivity guided program exploring the interaction of phytochemicals in the entire plant Primula macrocalyx with the organic anion transporters (OAT1 and OAT3) and microorganisms led to the elucidation of ten known flavones (1-4, 6-10, 12) and two previously undescribed flavones (5, 11). The
Primula macrophylla (Primulaceae) is reported as to be useful in asthma, restlessness, insomnia and fish poisoning. Antifungal and toxic activities of crude extract, fractions and a pure isolated compound exhibited statistically significant activities. Excellent antifungal activity was found in the
Primula heterochroma is indigenous to Caspian coast forests in the north of Iran. Total phenols, total flavnoids, total carotenoids and antioxidant capacity of 50 P. heterochroma accessions were investigated. The highest total phenol (1272.31 mg GA equivalent/100 g fresh weight) and total flavonoids
The genus Primula is the largest among the Primulaceae and is widespread mainly in the cold and temperate regions of the Northern Hemisphere. Since the beginning of the Twentieth century, several studies on the phytochemical composition of different species of Primula have been carried out. The main
High interest in chronic heart failure (CHF) is accounted for by its high incidence, poor prognosis, growing number of hospital admissions due to the heart failure relapse, and inadequate treatment. These facts necessitate a search for new pharmacological agents for the CHF correction. A 28-yr-old Naval F-14 aviator presented with complaints of flight-related anxiety occurring intermittently over an 18-mo period. Symptoms included sensation of strangeness, concern over the welfare of his radar intercept officer, flushing, nausea, and intense need to immediately land the aircraft.
