A number of Compositousplants belonging to the genera Sonchus, Laetuca and Ixeris are used in Chinese medicine as Bai-jiang-cao in northern China. Among them, Sonchus arvensis L., called Bei-bai-jiang and included in the Chinese Pharmacopoeia 1977 edition under the name Herba Sonchi Arvensis, is most widely used.In this paper, the morphological and histological characters of the drugs derived from genera Sonchus, Lactuca, and Ixeris, viz.

A number of Compositousplants belonging to the genera Sonchus, Laetuca and Ixeris are used in Chinese medicine as Bai-jiang-cao in northern China. Among them, Sonchus arvensis L., called Bei-bai-jiang and included in the Chinese Pharmacopoeia 1977 edition under the name Herba Sonchi Arvensis, is most widely used.In this paper, the morphological and histological characters of the drugs derived from genera Sonchus, Lactuca, and Ixeris, viz. Sonchus arvensis L., S. oleraceus L., S. asper (L.) Hill., Lactuca tatariea (L.) C. A. Mey., Ixeris chinensis (Thunb.) Nakai, Ⅰ. sonchifolia Hance and Ⅰ. denticulata (Houtt.) Stebb., are described, compared, and illustrated with line drawings. The results showed that the medullary bundle, appearing in the stem-pith of the above drugs derived from genera Sonchus, Lactuca and Ixeris, is of great significance for the systematics of the respective genera in Compositae and for the identification of the related crude drugs. The microscopical similarities and differences found among the genera Ixeris, Sonchus and Lactuca, through the microscopical investigation of the seven Compositous plants are summarized. The formation of perimedullary sclerenchyma in the stems of the above species is discussed. Keys for morphological and microscopical identification of the above plant identification and for seven drugs derived from Compositae and Herba Thlaspi derived from Thlaspi arvensis (Cruciferae) are also given.

本文对河南猕猴桃属Actinidia 14种及变种进行了叶的解剖学观察,结果发现: (1)、果枝叶柄的中心维管束沿着由弧形到圆形,再到圆形具髓内维管束的方向演化;(2)、叶柄近轴皮层中的2个小维管束的发生和连接方式与侧脉相同,为侧脉的一部分;(3)、本属植物叶片横切面的构造可分为三种类型:栅栏组织与海绵组织分化不明显的高山阴生型,栅栏组织与海绵组织同样发达的中生型,以及栅栏组织特别发达、海绵组织退化的阳生型。引种驯化时要考虑种间这种不同的生态习性。中华猕猴桃(A.chinensis planch.)果枝叶与营养枝叶差异明显,前者叶的同化组织和输导组织都较后者发达,生产上可作为参考;(4)、脉间区由网眼缺乏一个或几个边缘、脉梢分离末端较多的不完全发育的类型,经过一个中间类型,向网眼大小、形状均匀一致的发育完全的类型过渡;(5)、中间的亲缘关系和毛基部细胞的形状、列数、排列等有密切的关系。亲缘关系较近的种类,其表皮毛也具有相似或相等的基细胞形状、列数等。

There are two types of anomalous structures in the stem of Cyathulaa officinalis Kuan, one of which is 1--3 rings of anomalous bundles arranged in concentric or irregulare form, separated by parenchymatous or sclerenchymatous conjunctive tissue. The arrangement of anomalous bundles and the degree of selerification of conjunctive tissue in the internodes are variable at the different level of stem. The other type is 2 or 4 collateral or amphivasal medullary bundles arranged in a straight line occured in...

川牛膝茎中存在两种不同类型的异常结构。在正常维管系统的周围存在1~3轮同心环状或不整齐排列的异常维管束。异常维管束外韧型,分布在薄壁或厚壁结合组织中。不同节位茎中异常维管束的排列和结合组织的厚壁化程度有一定差异。茎中央有宽大的髓,其中分布有2个或4个髓维管束,在茎相对两侧下陷的浅沟之间的连线位置排成一条直线形。髓维管束的结构类型为外韧型或不完全的周木型。这些异常结构特征可作为中药川牛膝药材的鉴定指标。
