One third of samples of Arctii Fructus, commercially obtained in China, were found to be adulterated with fruits of five other species, Arctium tomentosum, Onopordum acanthium, Aucklandia lappa and Silybum marianum of the family Compositae, possessing achenes, and Amorpha fruticosa of the family Leguminosae possessing a legume. Ar. tomentosum fruit was the most frequent adulterant. These five fruits were distinguished from the fruit of Arctium lappa, the original Arctii Fructus, by the macroscopic morphological characteristics such as the size, color, presence or absence of ridge, spots and pits, remains of the style and pappus scar circle at one end, and by the microscopic characteristics such as outline of outer pericarp, presence or absence and the shape of crystals in the epicarp and endocarp, presence or absence of oil sac in the mesocarp, size and color of the palisade cells in the outer seed coat, presence or absence and the shape of crystals in the inner seed coat and cotyledon.

From the leaves of Poacynum hendersonii, six phenolic compounds were isolated and identified as quercetin, quercetin 3-O-glucoside, quercetin 3-O-sophoroside, isorhamnetin 3-O-glucoside, syringaresinol and (+)-pinoresinol 4-O-glucoside, by direct comparison with the authentic samples.

To identify the botanical origin of the commercial Chinese crude drug "Roucongrong (肉〓蓉)," a pharmacognostical study of genus Cistanche plants in Asia was carried out. In this study, the morphological and anatomical characteristics of specimens of three Cistanche species (C deserticola, C. tubulosa and C. salsa) from China and other Asian countries, and six commercial samples of the crude drug from China were examined. The results were as follows: (I) These three species could be distinguished from each other by the arrangement of vascular bundles in the transections of the stems, the morphology of vascular bundles in the scale leaves and the external morphology of the seeds. (II) C. tubulosa from China and Pakistan differ from each other in the size of plants and the longitudinal arrangement of vascular bundles in the stems and the scale leaves. (Ill) Six crude drug samples from Neimenggu, Ningxia and Xinjiang provinces of China were shown to be derived from either C. deserticola or C. tubulosa.

The Chinese crude drugs "Huajiao (花椒)" and "Jiaomu (椒目)," and the Japanese crude drug "Sansho (山椒)" are derived from mature fruit of genus Zanthoxylum plants of the Rutaceae family. "Huajiao" and "Sansho," are prepared from the pericarp, and used as an aromatic stomachic and "Jiaomu," is from the seed, and used as a diuretic. A market survey of these crude drugs in China and Japan, showed that there are samples of apparently different external morphologies, suggesting that there are samples of different botanical origins. To clarify the original plants of such crude drugs, a pharmacognostical study was made. This paper deals with the origins of "Sansho" in the Japanese market. Comparative anatomical studies were performed mainly on the pericarps and seeds of Z. piperitum, two kinds of Z. piperitum f. inerme (Asakura-zansho and Budo-zansho), Z. armatum var. subtrifoliatum, Fagara mantchurica, F. ailanthoides by optical and scanning electron microscopy, which showed that they could be distinguished from each other by the following characteristics: in the pericarp, the length of equatorial circumference, thickness of pericarps and endocarps, diameters of oil sacs, micro figure of cuticle and the number of epidermal cells over oil sacs on surface view; in the seed, the diameters of epidermal cells on surface view, the rate of inner sclereid layers in the outer seed coat, etc. The commercial samples examined were identified as a mixture of slightly immature pericarps of Budo-zansho and Asakura-zansho in a ratio of 9 : 1 or 6 : 4, a mixture of slightly immature pericarps of Z. piperitum, Budo-zansho and Asakura-zansho in a ratio of 8 : 1 : 1, or mature pericarps of Z. piperitum only.

From the plant commonly known as Indigo Plant (Polygonum tinctorium Lour., Shimane, Japan) , Tryptanthrin was isolated which had cytotoxic effects on malignant tumor cells. The cytotoxic effects on human solid cancer cells, leukemia cells, murine glioblastoma cell, colon cancer and malignant melanoma cells in vitro were assayed. Tryptanthrin induced remarkable necrotic and apoptotic changes in the malignant tumor cells.
