高速逆流色譜活性成分快速篩選
活性成分的篩選是發(fā)現(xiàn)先導(dǎo)化合物的重要途徑,也是闡明中藥藥效物質(zhì)基礎(chǔ)的關(guān)鍵步驟。由于中藥和天然藥物成分復(fù)雜多樣、含量參差不齊、活性成分多不明確,采用色譜技術(shù)分離純化后再進(jìn)行活性評價的傳統(tǒng)方法往往費時、費力,成本高昂。因此,從中藥天然產(chǎn)物中快速篩選活性成分成為一種發(fā)展趨勢。
高速逆流色譜(High-Speed Counter CurrentChromatography,HSCCC)利用被分離物質(zhì)在兩相中的分配差異實現(xiàn)物質(zhì)的高效分離,最大優(yōu)點是無固體支撐相,避免樣品的不可逆吸附、失活等問題,結(jié)合快速的生物活性檢測方法,特別適合從中藥天然產(chǎn)物中快速篩選活性成分[1]。本課題組也在這方面做了一些工作,比如在抗腫瘤、抗病毒活性篩選中的應(yīng)用[2,3]。結(jié)合本課題組的研究和近年來的研究報道,本文綜述了HSCCC在中藥和天然產(chǎn)物中快速篩選活性成分的應(yīng)用進(jìn)展。
1.1 HSCCC方法的開發(fā)
在中藥及天然藥物活性成分快速篩選過程中,HSCCC作為一項分離手段,其方法開發(fā)主要包括溶劑系統(tǒng)的篩選和運行方式的選擇。溶劑系統(tǒng)篩選是HSCCC方法開發(fā)中花費時間最多的程序,準(zhǔn)確快速的篩選合適的溶劑體系對于分離活性成分至關(guān)重要。在中藥及天然產(chǎn)物活性成分分離過程中,針對不同的化學(xué)成分,常采用不同的溶劑系統(tǒng),常用的溶劑系統(tǒng)可參考Ito Y等[4-6]的綜述文獻(xiàn)。在中藥及天然產(chǎn)物活性篩選中,通常活性成分的性質(zhì)并不清楚,常常應(yīng)用梯度洗脫模式以實現(xiàn)不同極性化合物的分離,如Ying H等[7]以正己烷-乙酸乙酯-正丁醇(1:4:0,1:2:0,0:1:0,0:4:1,0:4:2,0:2:2)梯度洗脫模式,從秋葵(Okra)提取物中分離得到抗腫瘤活性化合物;或采用雙向洗脫及洗脫-推出模式以擴展HSCCC的應(yīng)用,如Li L等[8]應(yīng)用雙向洗脫方式篩選可可豆提取物中抗氧化活性成分。
1.2 HSCCC聯(lián)用技術(shù)
在中藥及天然產(chǎn)物快速活性篩選中用到的HSCCC聯(lián)用技術(shù),主要包括以下幾種:
1.2.1 HSCCC與傳統(tǒng)色譜聯(lián)用
HSCCC與多種色譜技術(shù)(薄層色譜、硅膠柱色譜、大孔樹脂吸附柱色譜、凝膠柱色譜、超濾、超臨界流體萃取、固相萃取等)的聯(lián)合使用,可以提高分離效率。采用薄層色譜結(jié)合HSCCC,還可對分離流份進(jìn)行快速的初步分析。Yang C等[9]采用HSCCC結(jié)合硅膠柱色譜,從黃芪Astragalusaltaicus粗提物中逐級分離得到抗氧化活性的化合物isorhamnetin-3-gentiobioside、rutin以及narcissin。Li L等[10]采用HSCCC結(jié)合大孔樹脂吸附柱色譜、凝膠柱色譜,從紅花Carthamus tinctorius L.粗提物中分離得到羥基紅花黃色素等具有抗氧化活性的化合物。LiS等[11]采用HSCCC結(jié)合超臨界流體萃取從Chaenomelessinensis得到delphinidin-3-O-glucoside、cyanidin-3-O-glucoside、peonidin-3-O-glucoside、delphinidin、peonidin和malvidin。Liu Q等[12]采用固相萃取結(jié)合HSCCC從Rhizoma Chuanxiong中分離得到ferulicacid、protocatechuicacid和senkyunolide A等共11個化合物。
1.2.2 HSCCC與HPLC聯(lián)用
HPLC尤其是HPLC-MS作為一種強大的分析檢測和結(jié)構(gòu)鑒定手段,可以彌補HSCCC分離方法的不足,為HSCCC提供許多其他檢測技術(shù)所不能提供的被分離物質(zhì)的結(jié)構(gòu)信息。HSCCC結(jié)合LC/MS是一種分離分析復(fù)雜有機混合物的有效手段。LiS等[13]采用HSCCC結(jié)合超濾-LC-MS從Panax japlcusvar篩選得到具有抑制黃嘌呤氧化酶活性的24(R)-majoroside R1、chikusetsusaponin Iva、oleanolic acid-28-O-beta-D-glucopyranoside、notoginsenoside Fe、ginsenoside Rb2和ginsenoside Rd。Thakur M等[14]從肥皂草Saponaria officinalis粗皂苷混合物中篩選得到靶向增強抗腫瘤毒素的HSCCC流分,結(jié)合ESI-IT-MS導(dǎo)向分離得到活性成分bisdesmodic saponins。Wang Q等[15]利用HSCCC結(jié)合HPLC-ESI-QTOF-MS,從粉葛花Puerariae thomsonii Flos中篩選得到抗前列腺癌細(xì)胞活性成分tectorigenin,IC50為0.08mM。
1.2.3 結(jié)合活性篩選的多維HSCCC的應(yīng)用
HSCCC篩選活性化合物通常選用離線二維模式,經(jīng)過HSCCC分離的流份分別用于活性篩選和后續(xù)研究,如Zeng H等[16]建立離線二維篩選模式應(yīng)用于Semen cassia篩選得到抗氧化活性成分;Zhang Y Q等[17]運用類似方法從廣線金錢草Desmodium styracifolium中分離得到抑制血管緊張素轉(zhuǎn)化酶的活性成分C-glycosylflavone;Liu Q等[18]采用牛血清蛋白結(jié)合Fe3O4的磁性納米顆粒用于活性成分的篩選,離線二維HSCCC從Fructuspolygoniorientalis分離得到結(jié)合牛血清蛋白的活性成分。離線二維模式可以達(dá)到較理想的效果,這種模式在活性篩選時,通常將一維的流份進(jìn)行收集,回收溶劑后,再以適當(dāng)?shù)娜軇┤芙夂筮M(jìn)行各種活性的篩選。這種方式可以方便進(jìn)行多種活性的檢測,但操作相對復(fù)雜,且流份的干燥、轉(zhuǎn)移過程可能導(dǎo)致活性成分損失或降解。
為達(dá)到快速篩選的目的,近年來不少研究者發(fā)展了在線的活性篩選模式,通過切換閥、分流器和其他接口技術(shù)等的巧妙應(yīng)用,將HSCCC分離流份進(jìn)行在線的活性檢測、純度分析、結(jié)構(gòu)快速分析鑒定等,大大地拓展了HSCCC的應(yīng)用范圍。如ShiS等[19]建立HSCCC與抗氧化活性檢測在線聯(lián)用的方法篩選Selaginella moellendorffii中抗氧化活性的成分,將HSCCC分離的流份柱后分流,一部分在線與DPPH·溶液進(jìn)行反應(yīng),進(jìn)行抗氧化活性的檢測,實現(xiàn)了逆流色譜的分離與生物活性分離的同步,從而達(dá)到活性成分快速篩選和分離的目的,是HSCCC聯(lián)用技術(shù)未來發(fā)展的一個重要方向。
抗腫瘤活性成分常表現(xiàn)為細(xì)胞毒活性、抑制腫瘤細(xì)胞增殖和分化,誘導(dǎo)細(xì)胞凋亡等,因此通過細(xì)胞毒性測試等可以快速篩選中藥天然產(chǎn)物中的抗腫瘤活性成分,常用MTT法,XTT法和CKK法也有應(yīng)用,近年來,研究人員常運用HSCCC分離所得抗腫瘤活性成分(表1)。
