Disclosed is a method for extracting and purifying active constituents from honeysuckle (Thunb.) and its use. More particularly, this invention relates to an extraction and purification method of active constituents including sweroside from for honeysuckle stem (stem of honeysuckle where leaves are removed) by removing tannins, hardly soluble flavonoids, saponins, and the like. Thus obtained active constituents have better anti-inflammatory and analgesic effect, are safer and more stable than the conventional active constituents obtained from honeysuckle flower or honeysuckle leaves, and include sweroside which is an effective active ingredient of anti-inflammatory and analgesic drug.

This invention to a process of extracting and purifying biologically effective ingredients from combined medicinal plants and their plant extract composition and more particularly, to a process for effective extracting and purifying the biologically effective ingredients by mixing Clematis Radix, Trichosanthes root and Prunella Herba in a certain ratio, being useful for alleviating acute/chronic inflammation and also for inhibiting platelet/whole blood aggregation, abnormally proliferated immunocytes (e.g., B-lymphocyte, T-lymphocyte), inflammation-inducing enzymes (5-Lipoxygenase, Cyclooxygenase-I, Cyclooxygenase-II) and also scavenging activity on toxic active oxygen species when compared to a single plant extracts, together with their extract composition, which may be effectively used as an anti-inflammatory agent with analgesic effects, rheumatoid arthritis drug and agents for improving peripheral blood circulation.
