| 采用性状及显微鉴别方法对小花清风藤叶进行性状特征、组织构造及粉末特征研究,为小花清风藤提供科学准确的性状和显微鉴别特征。小花清风藤叶的性状特征为：叶深绿色，两面均无毛，近薄革质，长卵状披针形，叶片先端尖，叶柄短，气微，味淡。显微特征为：叶的上表下的栅栏组织2~3列,下表下的栅栏组织1列;主脉维管束的木质部导管呈放射状排列，外侧有环状排列的纤维；油细胞成片存在;表皮细胞的细胞壁均加厚,以不定式气孔多见;纤维长梭形成束存在;草酸钙簇晶众多，棱角大多短钝。本研究明确了小花清风藤的药材性状特征和显微特征，有助于减少混乱使用现象，增加药物使用的安全性及有效性，为进一步研究小花清风藤提供理论依据。 |

| Abstract: |
| In order to provide scientific and accurate macroscopic and microscopic characteristics to Sabia parviflora Wall. ex Roxb， the leaf trait, tissue structure and powder characteristic were studied. The results show that the leaf traits are as follows: dark green in color, glabrous on both sides, near thinly leathery, long ovate-lanceolate, pointed apex, short petiole, gas micro and light taste. The microscopic features are as the following: 2-3 rows of palisade tissue below the upper surface of the leaf, 1 row of palisade tissue beneath the lower surface; the xylem vessels of the main vascular bundle are arranged radially, and the outer side has annular fibers; the oil cells are present in pieces; the cell walls of the epidermal cells are thickened, the amorphous stomata are more common; the filaments of the long spindle are formed; the calcium oxalate clusters are numerous, and the angular edges are mostly short and blunt. This study identifies the macroscopic and microscopic characteristics. The identification method is simple, accurate and reliable. |
