Methods: GMSYS was stored at room temperature or refrigeration for 12 months. According to storage temperature and periods, ph and sugar content of GMSYS were measured. To determine the marker compounds of GMSYS, high-performance liquid chromatography analysis was performed. To estimate the anti-inflammatory effect of GMSYS, LPS-induced pro-inflammatory mediators and cytokines were measured in RAW cells. Results: There was no change in ph and sugar content depending on storage temperature and periods of GMSYS. The contents of gallic acid and mangiferin in both of room temperature and refrigerated decoctions reduced with increasing storage periods. Chlorogenic acid was time-dependently decreased in case of stored at room temperature. GMSYS significantly inhibited the LPS-induced production of nitric oxide, prostaglandin E 2 (PGE 2) and IL-6 in RAW cells. These effects equally maintained up to 3 months at both of room temperature and refrigeration. Since 4 months, the inhibitory effect of GMSYS on LPS-induced PGE 2 production was time-dependently reduced, and the decrease in PGE 2 inhibitory effect of decoction stored at refrigeration was lower than that of stored at room temperature. Conclusions: Our results indicate that the anti-inflammatory effect of GMSYS are maintained up to 12 months, but it shows optimal efficacy up to 3 months. It is recommended to store in a refrigeration for short periods since some components decrease as storage periods becomes longer.

NO level in supernatant was measured using Griess reagent. PGE 2, TNF-α and IL-6 in supernatant were measured by ELISA. L-NMMA and indomethacin were used as positive controls for NO and PGE 2, respectively. Triprolidine was used as a positive control for TNF-α and IL-6.

NO는 nitric oxide synthase (NOS) 에의해 L-arginine으로부터생성되는인자로신경전달, 면역조절및생체내항상성조절에중요한역할을한다 18). 그러나 NO의과도한생성은혈관투과성및부종등의염증반응유발로인해조직및신경손상과유전자변이등을초래할수있다 19). 또한대식세포가활성화되어염증반응이과도하게일어나면 cyclooxygenase-2 (COX-2) 에의해 arachidonic acid 로부터 prostaglandin이생성되며 20), 특히 PGE 2 는혈관생성을유도하여종양생성에기여한다 21). TNF-α 30

10 가미소요산전탕팩의보관온도및기간에따른지표성분함량및항염증효능비교연구 (31) 및 IL-6는염증반응을조절하는전염증성사이토카인으로다양한염증매게물질들을유도하고면역반응의조절에중요한역할을하지만, TNF-α 및 IL-6 역시과도하게생성되면암세포성장및동맥경화, 만성염증질환등이유발된다 22). LPS는그람음성균의세포외막에존재하며염증매개물질들을분비하도록대식세포를자극하는내독소로알려져있다 23-24). 따라서본연구에서는마우스대식세포인 RAW 264.7에서 LPS로염증반응을유도하여가미소요산전탕팩의보관온도및기간별로 NO, PGE 2, TNF-α 및 IL-6 분비량을측정하여효능이안정하게유지되는기한을설정하였다. 다양한성분들은안정성이유지되는 ph 및온도등의조건이다르기때문에탕액의 ph 및온도변화는탕액에함유된성분의변화를초래할가능성이있다. 따라서가미소요산전탕팩의보관온도및기간에따른 ph, 당도및지표성분의함량을확인함으로써장기보관에따른안정성을확인하였다. 가미소요산전탕팩을상온에보관할경우냉장보관하는것보다탕액의 ph 및당도의변화가큰폭으로나타났지만보관온도및기간에따른유의성은없는것으로나타나가미소요산전탕액의 ph 및당도가지표성분함량및항염증효능변화에영향을주지않을것으로사료되었다. 가미소요산의지표성분 gallic acid 25), chlorogenic acid 26), mangiferin 27), geniposide 28), paeoniflorin 29), berberine chloride 30), liquiritin apioside 31), nodakenin 32) 및 glycyrrhizin 33) 의항염증효능은이미알려진바있다. 특히가미소요산내비교적함량이높은 geniposide 및 paeoniflorin은 RAW 대식세포에서 LPS에의해생성된 NO와 PGE 2 생성및 IL-6 의발현을억제한다고보고되었으며 28-29), 본연구에서가미소요산전탕팩을상온및냉장에 12개월까지보관하더라도제조시점에비해함량의유의적인감소가나타나지않았다. 반면, gallic acid 및 mangiferin 의함량은전탕팩을상온및냉장보관하는기간이길어짐에따라점차적으로감소하였으며, chlorogenic acid의함량은전탕팩을상온에보관하는기간이길 어질수록감소하였다. 이러한사실로미루어보아가미소요산전탕팩을상온및냉장에보관하더라도함량변화가없는 geniposide 및 paeoniflorin에의해항염증효능이유지되기는하나보관기간이길어짐에따라 gallic acid, mangiferin 및 chlorogenic aicd 의함량이감소하면서항염증효능이점차적으로감소하는것으로판단된다. 또한가미소요산전탕팩의상온보관시냉장보관에비해항염증활성성분의함량이큰폭으로감소하는것으로나타나전탕팩을냉장보관할경우항염증효능이더오래유지되는것으로사료된다. 결론가미소요산전탕팩을상온및냉장보관할경우보관기간 4개월부터항염증효능이점차적으로감소하여 3개월이내에복용하는것이약효의손실이없을것으로판단된다. 특히보관기간 4개월이후부터상온에보관할경우냉장보관한것에비해항염증효능이큰폭으로감소하여장기보관시상온보다냉장보관하는것이약효유지에더이로울것으로사료된다. 이러한연구결과는향후가미소요산전탕팩의유통기한설정시기초자료로활용될수있을것으로기대된다. 감사의글본연구는한국한의학연구원에서지원하는 한약처방의과학적근거기반구축사업 (K17251) 에의해수행되었으며, 이에감사드린다. 참고문헌 1.
