New Collection of Crude Drugs in Chinese Pharmacopoeia 2010 I. Callicarpa Linn. and Related Items

Callicarpa Linn. (beautyberry) is one of the major genera in Verbenaceous, about 20 of which are medicinal plants. Beautyberry, called Zizhu in China, is a generic name of those species and largely used as hemostatic medicine. The Chinese Pharmacopoeia 2010 has admitted three new crude drugs from the genus of Callicarpa Linn. including Callicarpae Macrophyllae Folium, Callicarpae Caulis et Folium, and Callicarpae Formosanae Folium for the first time since the 1977 version of the Chinese Pharmacopoeia. In order to better understand these new crude drugs, we systematically described their bibliography, admission reasons, botanical identification, chemistry, and pharmacology. Several other species, out of national regulations but intensively studied and widely used, are also covered in this review.

枫香树叶对金黄色葡萄球菌和绿脓杆菌抑菌作用的观察

目的:探讨枫香树叶对金黄色葡萄球菌和绿脓杆菌的体外抑菌作用.方法:采用琼脂扩散法和试管连续稀释法测定枫香树叶对金黄色葡萄球菌和绿脓杆菌的体外抑菌作用及最低抑菌浓度.结果:枫香树叶对金黄色葡萄球菌和绿脓杆菌皆有抑菌作用,抑菌圈直径在14～25mm之间.不同方法提取的药液的抑菌作用有明显差别,其中枫香树叶水煎液抑菌作用最好, 对金黄色葡萄球菌(标准菌株和耐甲氧西林金黄色葡萄球菌)、绿脓杆菌(标准菌株及其临床多重耐药菌株)的最低抑菌浓度分别为0.5g/ml、1g/ml、0.25g/ml、0.125g/ml.结论:枫香树叶对金黄色葡萄球菌和绿脓杆菌具有较好的抑菌作用,可为临床治疗由金黄色葡萄球菌和绿脓杆菌引起的感染提供参考依据.

Anti-lymphangiogenic diterpenes from the bark of Calocedrus macrolepis var. formosana

Eight new diterpenes, 6α,7β-dihydroxyferruginol (1), 6α,7α-dihydroxyferruginol (2), 6α-hydroxyhinokiol (3), 4α-hydroxy-7-oxo-18-norabieta-8,11,13-trien-4α-ol (4a), 15,16-dehydrosugiol (5), 7-methoxy-6,7-secoabieta-8,11,13-triene-6,12-diol (6), 7α-acetoxyabieta-8,12-diene-11,14-dione (7), 7α-butyloxyethyloxyabieta-8,12-diene-11,14-dione (8), along with four known compounds, 6,7-dehydroferruginol (9), 12-hydroxy-6,7-secoabieta-8,11,13-triene-6,7-dial (10), 7α-11-dihydroxy-12-methoxy-8,11,13-abietatriene (11), and 11,14-dihydroxy-8,11,13-abietatrien-7-one (12) were successfully isolated from the bark of Calocedrus macrolepis var. formosana. The structures of all isolates were elucidated by physical data (appearance, UV, IR, optical rotation) and spectroscopic data (1D, 2D NMR, and HREIMS). Compounds 9, 10, 11, and 12 showed promising growth-inhibitory effect on human lymphatic endothelial cells (LECs). Among these compounds, compound 10 exerted the most potent anti-lymphangiogenesis property by suppressing cell growth and tube formation of LECs. In conclusion, the results revealed the anti-lymphangiogenic potentials of Formosan C. macrolepis var. formosana.
