From the whole plants of Swertia japonica Makino a mixture of two new bitter biphenyl glucosides biphenosides A and B, was isolated along with three known secoiridoid glucosides by the application of droplet countercurrent chromatography (DCCC). The structure of the biphenyl glucoside was established by chemical degradation and spectroscopic methods.
从日本獐牙菜的全草中，通过液滴逆流色谱法（DCCC）分离得到两种新的苦味联苯糖苷双酚苷A和B的混合物，以及三种已知的裂环环烯醚萜苷。通过化学降解和光谱方法确定了联苯糖苷的结构。
