[0087] Example 1: Preparation of new compound (KS513) from Pseudolysimachion rotundum var. subintegrum

[0088] 1-1. Preparation of Crude Extract

[0089] 4.0 kg of dried Pseudolysimachion rotundum var. subintegrum (according to GAP, KRIBB0020697, KRIBB's plant extract bank, cultivated in Soi-myeon Eumseong-gun Chungcheongbuk-do, 244, Korea; Taejeon, Korea) was cut into small pieces, and mixed with 10 L methanol mixture. The mixture was stirred at room temperature for 24 hours and extracted twice at 78° C. under reflux for 12 hours to collect the filtrate. Filter the extract with filter paper to remove residue. The collected filtrate was concentrated by a rotary evaporator (EYELA, N-2100, Japan) at 55°C-65°C under reduced pressure, and dried with a freeze dryer to obtain 397.4 g of dried crude extract.

[0090] 1-2. Preparation of purified extract

[0091] 200 g of the dried crude extract was dissolved in a mixed solvent (25% MeOH-water) and further purified by using prepa...

Description

technical field [0001] The present invention relates to: a new compound (KS513) isolated from Pseudolysimachion rotundum var. subintegrum, compositions containing the compound for preventing or treating allergic diseases, inflammatory diseases, asthma or chronic obstructive pulmonary disease and their uses. Background technique [0002] In general, an inflammatory response is a normal response of the human body associated with edema, pain, etc. in case of any infection of a tissue or cell causing some organic change of the tissue or cell. Recently, various types of cytokines have been found to be involved in inflammatory diseases. [0003] Allergic reactions can be divided into four categories according to the type of response, namely, type I, type II, type III, and type IV, or according to the type of time period from the time of resensitization caused by the allergen to the time of onset of the reaction. Sexual reactions are divided into two categories, namely, immediate ...
