为探究狼毒(月腺大戟)诃子汤制前后肠道毒性变化与成分组成变化的相关性,在整体动物模型水平灌胃给药,以小鼠的粪便含水量,肠道不同部位炎症因子及病理损伤情况为指标,比较月腺大戟生品二氯甲烷提取部位(二氯部位)、诃子汤制品二氯部位与模拟诃子汤制月腺大戟二氯部位的肠道毒性作用差异,考察诃子汤制对月腺大戟肠道毒性的影响。同时构建月腺大戟和诃子成分结构数据库,采用HPLC-TOF-MS分析这3个提取部位的二萜类成分与鞣质酚酸类成分组成变化。采用HPLC测定炮制前后月腺大戟饮片和炮制后锅壁残留物中的4种主要二萜类成分ent-11α-hydroxyabicta-8(14)、13(15)-dien-16,12-olide(HAO)、jolkinolide B(JNB)、fischeria A(FA)、jolkinolide E(JNE)的含量,考察诃子汤炮制是否对二萜类成分的含量与结构产生影响。结果表明,月腺大戟生品二氯部位组可显著增加小鼠的粪便含水量和各肠段炎症因子TNF-α和IL-1β释放水平,且发现肠道组织受损并伴随明显炎症细胞浸润,而与生品二氯部位组比较,模拟诃子汤制月腺大戟二氯部位组肠道组织损伤减轻,炎症细胞浸润减少,肠道毒性显著下降。质谱分析结果显示月腺大戟二氯部位模拟诃子汤制后二萜类成分含量无明显差异,但新增了大量来源于诃子的鞣质酚酸类等成分。HPLC结果显示,月腺大戟诃子汤炮制后4种萜类成分含量有不同程度下降,下降幅度在-0.35%~-19.74%,下降部分主要残留于锅壁,表明诃子汤制并未改变月腺大戟中毒性二萜类成分的结构。诃子汤中鞣质酚酸类成分拮抗作用是月腺大戟诃子汤炮制后肠道毒性下降的主要原因,民族药诃子汤炮制狼毒具有科学性。
