This report covers extraction, isolation, and characterisation studies on BIEB (Liliaceae) species. BIEB was extracted with hexane, chloroform, ethyl acetate, and methanol, respectively. Using chromatographic methods, two known bianthraquinones (, 7,10'-bichrysophanol and chrysalodin), three known anthraquinones (, chrysophanol; , chrysophanol-8-methyl ether; , aloe emodin) and one known steroidal compound (, daucosterol) were isolated from the chloroform extract. Structures of these isolated compounds were revealed by 1D and 2D NMR and HRMS spectroscopies. Absolute configurations of and were determined by single crystal X-Ray diffraction analysis.
本报告涵盖了对百合科植物BIEB的提取、分离和表征研究。分别用己烷、氯仿、乙酸乙酯和甲醇对BIEB进行提取。采用色谱方法，从氯仿提取物中分离出两种已知的双蒽醌（7,10'-二氢菲醌和金黄决明素）、三种已知的蒽醌（大黄酚；大黄酚-8-甲醚；芦荟大黄素）和一种已知的甾体化合物（胡萝卜苷）。通过一维和二维核磁共振以及高分辨质谱光谱确定了这些分离化合物的结构。通过单晶X射线衍射分析确定了和的绝对构型。
