运用反相高效液相色谱(RP/HPLC)法对21种蕨类植物中槲皮素、山柰酚的含量进行测定.使用Shimadzu C_(18) (250 mm×4.6 mm,5 μm)色谱柱,以甲醇-水溶液为流动相进行等度洗脱,流速1.0 mL/min,检测波长360 nm,进样量20 μL,柱温28 ℃.各对照品的质量浓度与色谱峰面积线性关系良好,具有较好的精确度和重复性,槲皮素、山柰酚的加标回收率分别为93%和95%.采用该方法分别对采自秦岭的21种蕨类植物的地上和地下部分进行测定,地上部分有19种含槲皮素、15种含山柰酚,其中毡毛石韦中槲皮素含量最高(2.11 mg/g),蜈蚣草中山柰酚含量最高(19.80 mg/g);而地下部分除有边瓦韦、大瓦韦含槲皮素(含量分别为0.11、0.12 mg/g)外,其余根状茎中几乎没有这两种黄酮类化合物;表明槲皮素与山柰酚在蕨类植物的地上部分广泛存在.
運用反相高效液相色譜(RP/HPLC)法對21種蕨類植物中槲皮素、山柰酚的含量進行測定.使用Shimadzu C_(18) (250 mm×4.6 mm,5 μm)色譜柱,以甲醇-水溶液為流動相進行等度洗脫,流速1.0 mL/min,檢測波長360 nm,進樣量20 μL,柱溫28 ℃.各對照品的質量濃度與色譜峰麵積線性關繫良好,具有較好的精確度和重複性,槲皮素、山柰酚的加標迴收率分彆為93%和95%.採用該方法分彆對採自秦嶺的21種蕨類植物的地上和地下部分進行測定,地上部分有19種含槲皮素、15種含山柰酚,其中氈毛石韋中槲皮素含量最高(2.11 mg/g),蜈蚣草中山柰酚含量最高(19.80 mg/g);而地下部分除有邊瓦韋、大瓦韋含槲皮素(含量分彆為0.11、0.12 mg/g)外,其餘根狀莖中幾乎沒有這兩種黃酮類化閤物;錶明槲皮素與山柰酚在蕨類植物的地上部分廣汎存在.

A reverse-phase high-performance liquid chromatographic(RP/HPLC)method was developed for simultaneous determination of quercetin and kaempferol in 21 ferns samples collected from Tsinling Mountains.The separation of the targets was performed on a Shimadzu C_(18) (250 mm×4.6 mm,5 μm) column by a constant gradient program using H2O(A) -methanol(B) as mobile phase at flow rate of 1.0 mL/min.The detection wavelength was set at 360 nm.The injection volume was 20 μL,and the column temperature was maintained at 28 ℃.The method showed good linear relationship,precision and repeatability.The recoveries were between 93% and 95%.The method was applied in the detection of quercetin and kaempferol in the above-ground parts and the underground parts of these 21 ferns.The result indicated that,in the above-ground parts,quercetin was existed in 19 species and kaempferol was existed in 15 species,in which the highest content of quercetin was 2.11 mg/g in Pyrrosia drakeana(Franch.) and that of kaempferol was 19.80 mg/g in Pteris vittata L.But in the underground parts of these 21 ferns,there was almost none of two kinds of elements in the rhizome of ferns except the existing of quercetin in Lepisorus marginatus and Lepisorus macrosphaerus(Baker) samples.The result also indicated that quercetin and kaempferol were widely existed in the above-ground parts of ferns samples.
