Identification 鉴别

Stem transverse section: epidermal cells with thick walls, glandular hairs present; cork layer visible in old stems. Cortex wide, with several rows of thick-walled cells on the outer side; some containing calcium oxalate prisms; secretory cavities present. Endodermis distinct. Phloem very narrow, with a few fibers on the outer side. Cambium ring indistinct. Xylem cells all lignified, vessels mostly arranged in a single row. Pith relatively large, with secretory cavities. Thin-walled cells containing calcium oxalate prisms and starch grains, some containing brown substances.
（1）本品茎横切面∶表皮细胞壁厚，有腺毛；老茎可见木栓层。皮层较宽，外侧为数列厚角细胞；有的含草酸钙方晶；具分泌腔。内皮层明显。韧皮部甚窄，外侧有少数纤维。形成层环不明显。木质部细胞均木化，导管多单行排列。髓部较大，具分泌腔。薄壁细胞含草酸钙方晶和淀粉粒，有的含棕色物。

Leaf surface of the drug: epidermal cells with wavy periclinal walls; stomata anisocytic, occasionally anomocytic. Glandular scales with 8-10 cells at the head and a single cell at the stalk.
本品叶表面观∶表皮细胞垂周壁波状弯曲；气孔为不等式，偶见不定式。腺鳞头部8～10细胞，柄单细胞。

Powder of the drug brown. Spiral vessels more common, diameter 7.5-25 μm. Secretory cavities mostly broken, some containing yellowish-brown secretions, secretory cells containing brown substances visible. Fiber walls thick. Calcium oxalate prisms diameter 7.5-26 μm. Glandular hairs composed of a single-cell stalk and a two-cell head. Stomata anisocytic. Brownish lumps visible.

Take another 1 ml of methanol to dissolve 0.5 mg of bergenin CRS as the reference solution. Carry out the method for thin layer chromatography<0502>, using silica gel G as the coating substance and a mixture of dichloromethane-acetic ether-methanol (5:4:2) as the mobile phase. Apply separately to the plate 3 μl of each of the above two solutions. After developing and removal of the plate, dry in air. Spray with a mixed solution of 1% ferric chloride and 1% potassium ferricyanide (1:1). The fluorescent spot in the chromatogram obtained with the test solution corresponds in position and colour to the spot in the chromatogram obtained with the reference solution.
（2）取本品粉末0.2g，加甲醇20ml，超声处理30分钟，放冷，滤过，滤液浓缩至1ml，作为供试品溶液。另取岩白菜素对照品，加甲醇制成每1ml含0.5mg的溶液，作为对照品溶液。照薄层色谱法（通则0502）试验，吸取上述两种溶液各3μl，分别点于同一硅胶G薄层板上，以二氯甲烷-乙酸乙酯-甲醇（5∶4∶2）为展开剂，展开，取出，晾干，喷以1%三氯化铁-1%铁氰化钾（1∶1）的混合溶液。供试品色谱中，在与对照品色谱相应的位置上，显相同颜色的斑点。
