1 藥材提。
1 Extraction of medicinal materials
(1)原輔料按企業(yè)標(biāo)準(zhǔn)或國家標(biāo)準(zhǔn)的規(guī)定,經(jīng)檢驗(yàn)合格后,備用;
(1) After passing the tests according to the enterprise standards or national standards, the raw material and supplementary material are prepared for future use;
(2)將(2)中的兩次提取藥液合并,濃縮至約每1g藥液相當(dāng)原生藥1.2g時,加入85%乙醇,使含醇量為65%,靜置24小時以上,取上清液,回收乙醇后,濃縮至約60~72g(送檢,乙醇含量應(yīng)2~2.5%)
(2) The extracted drug solutions obtained from (2) are combined, concentrated to a solution of 1.2g raw drug of about 1 g of drug liquid, added with 85% ethanol, allowing the alcohol level at 65 %, placed for 24 h or more, the supernatant was taken out. The ethanol was recovered and concentrated to about 60 ~ 72g (send to testing, the ethanol content should be 2~2.5%).
2 藥液的預(yù)處理:
2 Pretreatment of drug liquid:
一次離心:將收得的中藥濃縮液先放入冷庫(0-5℃)冷卻并靜置24小時以上,進(jìn)行第一次超速離心(16000轉(zhuǎn)/分鐘),棄去固形物部份,收集離心液體,計量為M1(千克)。
The first centrifugation: the TCM concentrated solution collected are put in the refrigeratory (0-5 ℃) to cool down and placed still for more than 24h. Then the first ultracentrifugation (16,000 r / min) was carried out to remove part of the solid substances, those centrifugal liquid was collected to measure at M1 (kg).
二次離心:將一次離心后收集的藥液M1,繼續(xù)放入冷庫(0-5℃)冷卻并靜置24小時以上,進(jìn)行第二次超速離心(16000轉(zhuǎn)/分鐘),棄去固形物部份,收集離心液體,計量為M2千克, 密封后,放置于恒溫恒濕庫房,0-5℃保存?zhèn)溆谩?gxgkickz.com
The second centrifugation: the TCM solution M1 collected for the first centrifugation was put in the refrigeratory (0-5 ℃) to cool down and placed still for more than 24h. Then the second ultracentrifugation (16,000 r / min) was carried out to remove part of the solid substances, those centrifugal liquid was collected to measure at M2 (kg). After being sealed, the liquid obtained was put in the warehouse of constant temperature and humidity and kept at 0-5℃ for future use.
