Study on Purification and Anti-inflammatory Effects of Total Lignans in Myristicae Semen / 中国中医药信息杂志

ABSTRACT

Objective To optimize purification technology of total lignans in Myristicae Semen; To study its anti-inflammatory effects. Methods Macroporous adsorption resin was used for enrichment and purification of total lignans in Myristicae Semen, with adsorption rate, desorption rate and content of total lignans as indexes. The resin type, concentration of eluent, sample weight and dosage of eluen were investigated. Anti-inflammatory effects were studied by determining swelling degree and inhibition rate of mice with ear swelling induced by xylene. Results Purification technology of total lignans was processed on type of AB-8 resin. 1 g crude extract was dissolved as sample; 40 mL preprocessed resin including 16 g resin was added and static adsorpted for 12 hours; 30% ethanol was used firstly to elute to colorless and then 300 mL 70% ethanol was used to elute; the eluent of 70% ethanol was collected. The purity of total lignans was 45.8%. There was statistical significance in ear swelling degree of total lignans in Myristicae Semen high-, medium-, and low-dosage groups compared with model group (P<0.05). Conclusion The purification technology of total lignans is stable and reproducible, and total lignans in Myristicae Semen has significant anti-inflammatory activity.
