在日本正仓院的“种种药账”中有13处记载了黑黄连。Asahina等研究认为,黑黄连与日本商品胡黄连相同。胡黄连为胡黄连属植物的地下部分,而胡黄连属只有胡黄连(Picrorhiza kurroa)与西藏胡黄连(P.scrophulariiflora)2种。胡黄连与西藏胡黄连地下部分的结构非常相似,很难分辨哪种是黑黄连的基原植物。本次对黑黄连、胡黄连和西藏胡黄连样品的90％丙酮提取物进行比较分析,并对关键化合物进行了分离鉴定。
There are 13 records of “black and yellow ties” in the “Pharmaceutical Accounts” in Japan’s Shozakura. Asahina et al.’s study believes that black berberine is the same as Japanese product Hu Huanglian. Hu Huang Lian is the underground part of the genus Phellodendron, and Hu Huang Lian is composed of only two species, Picrorhiza kurroa and P. scrophulariiflora. Hu Huanglian and the structure of the underground part of Hu Huanglian in Tibet are very similar, and it is difficult to tell which kind of primordial plant is the black and yellow lianlian. In this study, 90% acetone extracts of Scutellaria chinensis, Huhuanglian and Tibet huhuanglian were compared and analyzed, and key compounds were isolated and identified.
