目的:采用高分辨质谱及组学分析技术分析狭叶番泻叶及耳叶番泻叶化学成分差异,并建立狭叶番泻叶中掺伪耳叶番泻叶的快速检查方法。方法:采用超高效液相色谱-四极杆飞行时间串联质谱(UPLC-Q TOF MS),分别采集13批狭叶番泻叶和9批耳叶番... 目的:采用高分辨质谱及组学分析技术分析狭叶番泻叶及耳叶番泻叶化学成分差异,并建立狭叶番泻叶中掺伪耳叶番泻叶的快速检查方法。方法:采用超高效液相色谱-四极杆飞行时间串联质谱(UPLC-Q TOF MS),分别采集13批狭叶番泻叶和9批耳叶番泻叶的正谱和负谱MSE数据。采用Agilent ZORBAX SB-C18(100 mm×2.1 mm,1.8μm)色谱柱,柱温30℃,以乙腈(A)-1%乙酸(B)为流动相,流速0.3 mL·min^(-1),进样体积1μL;采集质量范围为m/z 50~1200。运用组学分析软件QI对狭叶番泻叶和耳叶番泻叶负谱数据进行正交偏最小二乘法判别分析,筛选出7个耳叶番泻叶特征性成分,并对其中的1个主要特征性成分进行了分离鉴定。进一步以主要特征性成分为指标性成分建立了快速检查狭叶番泻叶中掺伪耳叶番泻叶的UPLC方法,并应用于27批狭叶番泻叶样品及3批自制阳性样品的测定。结果:狭叶番泻叶和耳叶番泻叶的化学成分差异显著,经鉴定耳叶番泻叶中特有成分为kaempferol 3-O-(2”-O-apiofuranosyl)rutinoside。在狭叶番泻叶中掺伪耳叶番泻叶的UPLC检查方法中,该特有成分的精密度(RSD=1.3%)、重复性(RSD=1.3%)和稳定性(RSD=0.58%)均符合要求。27批狭叶番泻叶样品中23批未检出kaempferol 3-O-(2”-O-apiofuranosyl)rutinoside;4批狭叶番泻叶样品及3批自制阳性样品中检出kaempferol 3-O-(2”-O-apiofuranosyl)rutinoside。结论:本研究应用UPLC-Q TOF MS技术结合OPLS-DA分析方法成功将狭叶番泻叶和耳叶番泻叶进行了区分,分离并鉴定出耳叶番泻叶的主要特征性成分,并建立了快速筛查狭叶番泻叶中掺伪耳叶番泻叶的UPLC方法,为狭叶番泻叶的质量控制及质量标准的完善提供了依据,为中药材掺伪鉴别研究提供了思路和方法。 展开更多

Objective: The present study deals with the investigation of antiplasmodial potential of leaf methanolic extract of Aegle marmelos, Aristolochia indica and Cassia auriculata against Plasmodium berghei(NK65)infected mice.Methods: The chloroquine-sensitive parasites P. berghei(1 × 106) were inoculated into Swiss albino mice intraperitoneally. The methanol extracts of three herbal plants were orally administered in P. berghei infected mice which were further assessed using the four-day suppressive test at different doses of 150, 300 and 600 mg/kg per day. Chloroquine(CQ) was used as the standard drug with of 1.25, 2.5 and 5 mg/kg concentrations and was orally administered.Results: The leaves of A. marmelos, A. indica, and C. auriculata were found to suppress P. berghei parasitaemia in Swiss albino mice by(67.0 ± 4.02)%,(72.0 ± 8.44)% and(52.7 ± 2.06)% at 600 mg/kg/d with ED50 values of 284.73, 233.77 and 562.48 mg/kg, respectively. These herbal plants increased the mean survival time of infected mice and prevented body weight loss. GC-MS analysis revealed the presence of hentriacontan-16-one(C31 H62 O) in A. indica extract. The histopathology study showed non-toxic to kidney and liver at 600 mg/kg/body weight.Conclusions: Overall results revealed that herbal plants may be active in the development of novel and cheap antimalarial compounds. 展开更多
