Abstract:
PURPOSE: Pregomisin having antagonistic activity on a platelet activating factor receptor isolated from Schisandrae fructus, a pharmaceutical composition containing the pregomisin, pharmaceutically acceptable carrier and excipient and their use are provided. Therefore, the composition can be used for treatment and prevention of inflammatory disease related to a platelet activating factor receptor. CONSTITUTION: An antagonist on a platelet activating factor receptor contains pregomisin of formula 2 isolated from Schisandrae fructus as an effective component. A pharmaceutical composition for treatment and prevention of inflammatory disease related to a platelet activating factor contains the pregomisin, a pharmaceutically acceptable carrier and excipient.
Abstract:
PURPOSE: A compound, tylinoside, having an anticomplement activity is isolated from Magnolia flos and the structure thereof is examined by spectroscopy. CONSTITUTION: Tylinoside of formula (I) is isolated from Magnolia floes and the pharmaceutical composition, containing the isolated compound of formula (I) as an effective ingredient of complement activity regulating agent, is prepared. Thus, Magnolia flos is crushed and extracted with methanol and the filtrated liquid is vacuum concentrated, suspended in distilled water, and extracted with ethylacetate. The extracts are fractionated with silica gel column chromatography to isolate the tylinoside of formula (I).

Abstract:
PURPOSE: A complement activity controlling agent containing at least one of ginseng saponin or sapogenin compounds capable of being produced by extracting, separating or purifying ginseng or red ginseng and a therapeutic agent associated with complement activity is provided which can be effectively used for treatment of various diseases such as asthma, allergy, atopic dermatitis or the like. CONSTITUTION: The complement activity-controlling agent contains at least one of ginseng saponin or sapogenin compounds represented by the formula 1. The saponin or sapogenin compounds are ginsenoside Ra1, ginsenoside Ra2, ginsenoside Rb1, ginsenoside Rb2, ginsenoside Rc, ginsenoside Rd, ginsenoside Re, ginsenoside Rf, ginsenoside Rg1, ginsenoside Rg2, ginsenoside Rh1, ginsenoside Rh2, ginsenoside Rh4, ginsenoside R0 and olenolic acid.
Abstract:
PURPOSE: A lignan compound isolated from magnolia floss or extract of magnolia floss having excellent inhibition activity for generation of leukotrienes is provided, which can be used as a medicine for various inflammatory disease like as asthma, whooping cough, arthritis, septic shock, ischemia, allergic rhinitis related with activity of leukotrienes. CONSTITUTION: A lignan compound is gained by the process of: extracting from magnolia floss using primary alcohol like as methanol; concentration; adding distilled water and hexane; isolating hexane layer; concentrating and adding ethylacetate; isolating ethylacetate layer; concentrating and separating by silicagel column chromatography; gaining dimethoxy aschantin of formula 1, aschantin of formula 2, fargesin from 8th part, and gaining pinoresinol dimethyl ether of formula 4, mandolin, liroresinol-B-dimethyl ether and (+)-epimandolin A from 11th part using reverse-phase silicagel column chromatography and high speed liquid column chromatography repeatedly.
