picrorhiza scrophulariiflora/抗过敏

Picroliv, a standardised iridoid glycoside fraction from the root and rhizome of Picrorhiza kurroa at a dose of 25 mg kg-1 p.o. inhibited passive cutaneous anaphylaxis in mice (82%) and rats (50-85%) and protected mast cells from degranulation (60-80%) in a concentration-dependent manner. Its effect

Seven new acylated iridoid glycosides, picrorhizaosides A-G (1-7), were isolated from the methanol extract of the rhizomes of Picrorhiza kurroa Royle ex Benth. (Plantaginaceae), in addition to six known iridoid glycosides (8-13). The structures of these new iridoids, including their stereochemistry,

UNASSIGNED Picrorhiza kurroa (PK) belongs to Scrophulariaceae family and is a representative endemic, medicinal herb, widely distributed throughout the higher altitudes of alpine Himalayas from west to east, between 3000 and 4500 m above mean sea level. UNASSIGNED The objective of the present study
