Studies on the Identification of Chinese Drug Material in Yams (Dioscorea spp.)

本研究利用組織切片法進行山藥台農1號、山藥台農2號、大汕二品系、大汕三品系、二刺品系、中國長品系、紫玉血薯品系、自然品系、大陸淮山品系、基隆山藥品系及黃藥品系等十二種山藥品種／種之基原鑑定，從塊莖組織中的木栓層、皮層、厚壁細胞、黏液細胞、束針晶體、樹脂道、澱粉粒形態、粉末顏色等組織的不同，可區分十二種山藥品種／種之差異性。並將切片之觀察結果歸納成顯微特徵檢索表。 The botanical origins of the Chinese drug material in yams were clarified by anatomical studies of the plant materials, twelve cultivarities/species of Dioscorea. These plant materials were TNG1(Dioscorea alata L.), TNG2(D. alata L.), 70W34(D. alata L.), 70W35(D. alata L.), 70W47(D. alata L.), 80W02(D. alata L.), 70R16(D. alata L. var. purpurea (Roxb) M. Pouch), 70W41(D. batatas L.), 70W59(D. batatas L.), 70W43(D. japonica Thumb.var. pseudojaponica (Hay.) Yamamoto), 70W37(D. bulbifera L.). There were some differences found in the cork layer, cortex, scleroid, mucilage cell, raphide, resin canal, starch grain characters and powder color of the underground stems. Therefore, these twelve cultivarities/species can be clearly distinguished from each other. The results are shown in the index table given."
