1. Too-gin-chie, the dried herb of Chenopodium ambrodoides L., has been used as anthelmintic, for the round and hook worms. Research work in recent years showed that it has good anthelmintic activity. 2. A brief review of the literature and detailed descriptions of the macroscopical and microscopical characters of the drug are given with 16 illustrations. 3. The more important microscopical features of the drug are: (1) epidermis of the stem, with non-glandular hairs of two types: 6 to 18-celled uniseriate...

1. Too-gin-chie, the dried herb of Chenopodium ambrodoides L., has been used as anthelmintic, for the round and hook worms. Research work in recent years showed that it has good anthelmintic activity. 2. A brief review of the literature and detailed descriptions of the macroscopical and microscopical characters of the drug are given with 16 illustrations. 3. The more important microscopical features of the drug are: (1) epidermis of the stem, with non-glandular hairs of two types: 6 to 18-celled uniseriate hairs, up to 920μ in length, with small apical cells, and 18 to 24-celled biseriate hairs; (2) glandular hairs also of two types: those having 6 to 9-celled stalk and 2 to 3-celled head, and those having 3 to 5-celled stalk and 1-celled sac-shaped head. 4. The essential oil of the drug has been studied, and its content, physical and chemical constants are given.

本文介紹了土荆芥在民間的应用的情况,詳細地描述了土荆芥Chenopodium ambrosioides L.原植物的形态。并与洋土荆芥C.ambrosioides var.anthelminticum Gray作了比較。根据形态組織学的研究結果,对土荆芥的莖、叶、苞叶、果实和种子的外部形态、內部构造与粉末特征都作了詳細的描述,并和洋土荊芥Chenopodium ambrosioides var.anthelminticum Gray作了組織粉末特征的比較,本文附有說明图片16幅。本文还报告了土荆芥揮发油的含量测定結果,对揮发油的此重、旋光度、折光率及药典所列各項規定进行了检查,并与洋土荆芥油作了对照比較。

The chemical composition of the volatile oil from Chenopodium ambrosioides L.grown in Hubei was analysed by GC/MS/DS technique.Eighty components have been identified.The major components were menthol (31 33%),α terpinene (13 21%),carvomenthenol (8 53%),p cymene (8 34%),and 1,8 cineole (7 42%) etc.The total content of the 80 components is 99 112% of the volatile oil.

用色谱-质谱联用技术对湖北产土荆芥挥发油的化学成分进行了分析。鉴定了80种组分。其中主要组分是:薄荷醇(31.331%)、α-松油烯(13.210%)、香芹艹孟烯醇(8.526%)、对伞花烃(8.343%)、1,8-桉叶油素(7.417%)等5种化合物。被鉴定的80种成分,共占挥发油总含量的99.112%。

OBJECTIVE To study the in vitro permeability of osthol across full thickness rat skin treated with enhancers.METHODS The modified Valia-Chien diffusion cells was used.RESULTS The enhancers including chenopodium,menthol and Azone were able to increase the osthol percutaneous steady-state fluxes3.09,3.41 and 4.38 times to the control,respectively.To explain the enhancement mechanism of the promoters used,the diffusion and partitioning coefficients for osthol were calculated.It was indicated that chenopodium,menthol...

OBJECTIVE To study the in vitro permeability of osthol across full thickness rat skin treated with enhancers.METHODS The modified Valia-Chien diffusion cells was used.RESULTS The enhancers including chenopodium,menthol and Azone were able to increase the osthol percutaneous steady-state fluxes3.09,3.41 and 4.38 times to the control,respectively.To explain the enhancement mechanism of the promoters used,the diffusion and partitioning coefficients for osthol were calculated.It was indicated that chenopodium,menthol and Azone increased the diffusion coefficients of osthol to 1.10,2.18 and 6.30 times respectively to the control,while decreased the SC/medium partition coefficients to 0.309,0.341 and 0.438 times respectively.CONCLUSIONS It was shown that the main enhancement mechanism of three skin penetration enhancers used were to destroy the barrier function of stratum corneum,reduce the resistance of drug transport through the skin and increase the diffusion coefficients of osthol.

目的 研究渗透促进剂对蛇床子素的体外经皮渗透的影响。方法 将蛇床子有效部位制成饱和生理盐水溶液 ,采用Valia Chien扩散池考察了土荆芥油、薄荷醇和月桂氮酮 (Azone) 3种渗透促进剂对蛇床子素经离体鼠皮渗透性的影响。结果 应用土荆芥油、薄荷醇和Azone为渗透促进剂 ,药物的稳态流量与对照组比较均有提高 ,增渗倍数分别为 3.0 9,3.4 1及4 .38;药物的表观扩散系数分别提高为 1.10 ,2 .18及 6 .30倍 ,但表观分配系数却分别降低为 0 .30 9,0 .341及 0 .4 38倍。结论  3种渗透促进剂的作用机制主要为改变角质层的通透性 ,减低了药物经皮肤渗透的阻力 ,提高了药物在皮肤角质层的扩散系数。
