본 연구결과에서 홍경천 추출물은 L6 근육세포에서 산화적 손상으로 인한 세포사멸과 ATP 생성량 감소를 유의적으로 억제하였을 뿐만 아니라 마우스에 2주간 200 mg/kg 농도로 경구투여시 통계적으로 유의하지는 않았으나 treadmill 운동시간을 증가시켰고 glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactate dehydrogenase, creatinine, lactate 등의 혈액지표를 개선시켰다. 따라서 홍경천은 과도한 운동 스트레스로 인한 손상을 억제할 수 있는 소재로써의 큰 가능성을 가지고 있는 것으로 판단된다.

Chemical investigation of the roots of Rhodiola sachalinensis A. Bor. (Crassulaceae) has led to the isolation of four flavonoids. Structures of these compounds were identified as $kaempferol-3-O-{\beta}-D-glucopyranoside$ (1), $kaempferol-3-O-{\beta}-D-sophoroside$ (2), $herbacetin-3-O-{\beta}-D-glucopyranoside$ (3) and $herbacetin-7-O-{\beta}-D-glucopyranosyl(1{\rightarrow}3)-{\alpha}-L-rhamnopyranoside$ (4) by the analysis of spectroscopic evidences and comparision with the data of authentic samples.

The study was conducted to investigate the condition for mixed fermentation of Rhodilola sachalinensis with red ginseng using Lactobacillus acidophillus 128 and the changes of physicochemical properties and antioxidant activities before and after the lactic acid fermentation was examined. In the single fermentation of Rhodiola sachalinensis extract, the pH and titratable acidity rarely changed, and the number of lactic acid bacteria decreased greatly. On the other hand, in the lactic acid fermentation of Rhodiola sachalinensis-red ginseng mixed extract of 50% red ginseng content, the pH decreased, whereas the titratable acidity and the number of lactic acid bacteria increased. The solid content of optimal mixed extract for lactic acid fermentation was 0.5%. Sugar content decreased during fermentation, but total phenolic compounds tended to increase during fermentation. The salidroside and p-tyrosol content of the initial Rhodiola sachalinensis-red ginseng mixed extract was 419.5 mg% and 60.1 mg%, respectively; after fermentation, the salidroside content after lactic acid fermentation decreased greatly to 81.8 mg%, and the amount of p-tyrosol increased greatly to 324.9 mg%. The DPPH scavenging activity of Rhodiola sachalinensis-red ginseng mixed fermentate was 78.1% at 0.1% concentration, showing a tendency to increase as compared to 50.3% of Rhodiola sachalinensis-red ginseng mixed extract before the fermentation (p<0.05); it was a higher antioxidant activity as compared to the single fermentation of Rhodiola sachalinensis or red ginseng.

홍경천(Rhodilola sachalinensis A. Bor)의 잎절편로부터 부정아를 유도하고자 BA와 kinetin을 처리한 결과, BA의 처리가 kinetin의 처리보다 부정아 유도와 신초의 생장에 양호한 것으로 나타났으며, 특히 BA 1 mg/L처리에서 부정아 유도빈도와 신초길이는 각각 71%와 3.0 mm로 가장 높게 나타났다. 또한 고빈도의 부정아를 유도하고자 다양한 농도의 putrescine를 처리한 결과, putrescine 100 mM 처리에서 부정아 유도빈도가 BA 1 mg/L 단용처리보다 약 20%가 증가되었고 신초길이 역시 약 10 mm가 증가된 것으로 나타났다. 이상의 결과에서 유도된 부정아는 생장조절물질이 포함되지 않은 1/2MS배지에서 발근과 신장이 정상적으로 이루어졌으며 약 7 cm 정도 생장한 유식물체는 peatmoss:sand가 1:1로 혼합된 상토에서 약 95%이상 정상적으로 순화되었다.

This study was performed to compare effect of anticancer activities on Rhodiola sachalinensis by ultrasonifi-cation process and solvent. Compared the yield to the water extracts (WE), wafer extracts with ultrasonification (WEU) at60, loot and ethyl alcohol extracts (EE), ethyl alcohol extracts with ultrasonification (EEU) at 60 ${\circ}$C from Rhodiola sachalinensis. Experimental studies were progressed through the anticancer activities such as cell cytotoxicity, inhibition activities of cell growth. The cell cytotoxicity using human embryonic kidney cell (HEK293) was showed cytotoxicity of below 26.26%by extracts of Rhodiola sachalinensis in 1.0 mg/ml concentration, The anticancer activities were increased in over 70% by extracts of Rhodiola sachalinensis in A549, AGS, Hep3B and MCF-7 cells. From the results, the extract Rhodiola sachalinensis were showed useful anticancer activities.
