Advance basic research has confirmed that the alkaloids extracted from thunberg fritillary bulb which is widely used in clinical medicine in vitro and in animal experiments have reversed MDR of leukemia. It will increase resistance of acute leukemia cells anticancer drug concentration and lower resistance the expression of Pgp. Pre-Clinical Experimental Research also shows that the conventional chemotherapy combined with the powder of thunberg fritillary bulb for the treatment of acute leukemia. Clinical complete response rate was higher, especially for patients with refractory or relapsed leukemia patients better clinical remission rate. In addition, Caladium particles Slices with chemotherapy in the treatment of RAL Clinical studies also show the Chinese refractory leukemia improve clinical efficacy safe and reliable.
先期基础研究已证实：临床常用的化痰散结中药浙贝母提取的生物碱体外及动物实验均有逆转白血病多药耐药的生物活性，能增加耐药的急性白血病细胞内抗癌药物浓度，降低耐药蛋白Pgp的表达；临床预实验研究也表明，常规化疗方案配合浙贝母粉用于急性白血病临床治疗，其临床完全缓解率明显高于对照组，尤其对难治及复发白血病患者临床缓解率更佳；此外，单药浙贝母颗粒配合化疗治疗RAL的临床研究亦显示中药在提高难治性白血病临床疗效方面安全可靠。

The constituents of bulb of F. puqiensis were studied. Five steroid alkaloids were isolated. The plane structure and stereoscopic configuration of 4 compounds were elucidated. They are named as puqienine A (FP-33), puqienine B (FP-3), N-demethyl-puqietinone (〓 FP-34) and puqietinone (〓, FP-9). Puqienine A and N-demethyl-puqietinone are new compounds. Puqienine B is as same as FPQ-3 elucidated by Prof.
对F.puqiensis鳞茎化学成份进行了研究，分得5个甾体类生物碱成分，并采用 UV、IR、EI-MS、1D-NMR，HHCOSY、CHCOSY、HMBC和X-RAY等光谱技术和理化常数测定，鉴定出4个化合物的平面结构和立体构型，分别为蒲圻贝母碱甲（puqienineA，FP-33）、蒲圻贝母碱乙（puqienineB，FP-3）、N-去甲蒲贝酮碱（N-demethyl-puqietinone，FP-34）和蒲贝酮碱（puqietinone，FP-9），其中蒲圻贝母碱甲和N-去甲蒲贝酮碱为新化合物。

Thunberg Fritillary Bulb is one of the most popular Traditional Chinese herbs. Some trials in vivo and animals indicated that Peimine and Peiminine, extracted from Thunbery Fritillary Bulb, have the function of reversing MDR of two different kinds of mechanisms. They can improve the cytotoxic of ADR to cancer cells by 5～10 folds under concentration of 10% cancer cell growth inhibitory rate. Peimine and Peiminine not only feather typical character of modifier of MDR, but also differ from other moldifiers such as Calcium channel blocker, Cyclosporines in chemical structure, they belong to cevine groups alkaloid, a subgroup of C-Nor-D-homosteroid alkaloid.
浙贝母是临床常用中药，体外及动物试验证明，浙贝母中的有效活性成分贝母甲素和贝母乙素具有逆转肿瘤细胞MDR的作用，而且能逆转两种不同机制的多药耐药肿瘤细胞的耐药性，在无明显细胞毒剂量下，可使阿霉素对耐药肿瘤细胞的杀伤活性提高5-10倍，不但具备明确的多药耐药逆转剂的特征，而且在化学结构上属异甾类生物碱中的瑟文类生物碱，完全不同于钙离子拮抗剂、免疫抑制剂和其它现有的耐药逆转剂，具有作用靶点宽、化学结构独特的特点。

Results Bulbus alkaloids easily formed molecular ions(superscript + in MS and dimerized easily in alcohol solution, which did not dimerize in acidity solution. Collision induced dissociation made these alkaloids easily lose a molecule of H2O. The MS spectra of the extracts of five Bulbu Fritillartae species indicated that the major molecular ions were similar to each other, but different varieties showed very different relative abundances of these molecular ions.
结果 在正离子一级质谱中，贝母生物碱易形成带一个正电荷的准分子离子，并且在中性醇溶液中，贝母生物碱易形成二聚体，在酸性介质中则无此现象；二级碰撞诱导解离易使贝母生物碱脱去一分子水；5种贝母对照药材的总生物碱提取液的一级电喷雾质谱图显示，主要分子离子峰基本相同，但因品种不同相对丰度差异较大。
