COMPOSITION FOR PREVENTING AND CURING OSTEOPOROSIS COMPRISING TWO TERPENOIDS, FRACTION OR EXTRACT FROM EUPHORBIA KANSUI

摘要

A composition for preventing and treating osteoporosis comprising terpenoids isolated from Euphorbia kansui or the extracts thereof is provided to inhibit bone absorption of osteoclasts without side effects. The composition for preventing and treating osteoporosis comprises kansuinine A represented by the formula(1) and gamma-euphorbol represented by the formula(2) or the extracts thereof. The kansuinine A represented by the formula(1) and gamma-euphorbol represented by the formula(2) are isolated by extracting and concentrating Euphorbia kansui with methanol, suspending the concentrated extract of Euphorbia kansui in water, and adding nucleic acid into the suspension to separate a nucleic acid layer, adding methylene chloride into a water layer obtained by separating the nucleic acid layer to obtain a methylene chloride fraction, and subjecting the methylene chloride fraction to chromatography.
