利用 RP- HPL C法,采用外標(biāo)法測定了三通風(fēng)濕康膠囊中天麻素的含量。對三通風(fēng)濕康膠囊中天麻素的提取方法、測定條件進行了選擇,實驗結(jié)果顯示用甲醇超聲處理,過中性氧化鋁柱方法提取較好。該方法的加樣回收率為 99.2 9%,RSD為 0 .33%

Contents of gastrodin in Santong Fengshikang Capsule was determined by RP-HPLC with the use of external standard. Conditions for the extraction and determination of Gastrodin from Santong Fengshikang Capsule were optimized. Results showed that the samples should be extracted with methanol under ultrasonic wave, then passed through Al2O3 column. The average recovery of this method was 99.29 % and RSD 0.33 %.
