1. A brief review of the assay processes of liquorice root is made. 2. After investigating the more important stages in the processes of Houseman and Fahmy, the following improvements are made to obtain a more complete separation of glycyrrhizic acid: (1) duration for the precipitation of glycyrrhizic acid is prolonged from 2-fe- hours employed by Houseman to 24 hours; (2) concentration of the sulphuric acid usad for the precipitation of glycyrrhizic acid is changed from 0.3 per cent employed by Houseman to...

1. A brief review of the assay processes of liquorice root is made. 2. After investigating the more important stages in the processes of Houseman and Fahmy, the following improvements are made to obtain a more complete separation of glycyrrhizic acid: (1) duration for the precipitation of glycyrrhizic acid is prolonged from 2-fe- hours employed by Houseman to 24 hours; (2) concentration of the sulphuric acid usad for the precipitation of glycyrrhizic acid is changed from 0.3 per cent employed by Houseman to 1.4 per cent; (3) temperature for the precipitation of glycyrrhizic acid is lowered from room temperature employed by Fahmy to 6-7°C. 3. Benedict's quantitative solution is used in place of Fehling's solution in the titration of reducing sugars, because the former solution is more stable and has better keeping properties. 4. An improved process for the assay of liquorice root is described. Five samples of Chinese liquorice root have been assayed by this method. The results obtained are as follows: water-soluble extractives, 26.17—35.59 per cent; glycyrrhizic acid 5.49—10.04 per cent; total reducing sugars, 4.70—10.97 per cent; starch and gummy matter, 4.17—5.92 per cent; water, 8.04—8.93 per cent; ash, 3.06—4.24 per cent; acid-insoluble ash, 0.25—0.65 per cent. The above results showed that the samples assayed fully conform with the requirements of the pharmacopoeias of most countries.

1.本文简述了前人分析甘草成分所用的方法,並對Houseman氏及Fahmy氏所用方法的主要步驟進行了比較研究,改進了他們的操作方法. 2.為了便利更完全地分離甘草根中所含的甘草酸,我們進行了下列修改:(1)將Houseman氏沉澱甘草酸的時間由2.5小時延長至24小時;(9)將Houseman氏沉澱甘草酸時所用的硫酸濃度由0.3%提高至1.4%;(3)將Fahmy氏沉澱甘草酸時的温度由常温降低至6—7C°. 4.由於非林氏試液很不穩定,應用、貯存均感不便,故採用班乃第氏定量試液.用轉化後的糖液滴定一定量的班乃第定量試液,以测定總還原糖量. 6.本文報告了對五種国產甘草成分分析的結果;水溶物26.17—35.59%,甘草酸5.49—10.04%,總還原糖4.70—10.97%,澱粉及膠質4.17—5.92%,水分8.04—8.93%,灰分3.06—4.24%,酸不溶性灰分0.25—0.65%.並證明上述樣品完全符合於中、蘇、英、日、美各国藥典規定的甘草品質標準.

An ecological survey of ergot production on various hosts in Changpei and Kuyan districts was made in 1957.Alkaloid contents of ergot collections from the above mentioned districts as well as from Northeastern China were analysed. The average percentages of ergot infection of Aneurolepidium chinese,A.dasystachys,Hordeum brevisubulatum,H.violaceum,Secale cereale,Agropyron cristatum and Clinelymus dahuricus were 68.48,60.97,60.00,50.00,42.00,14.00 and 6.59 respectively.Calamagrostis epigeios was very lightly infected,while there was no infection at all on wheat,barley and Bromus inermis.A.dasystachys,A.chinense,and Clinelymus dahuricus were most widely distributed among wild hosts,and their average numbers of culms per square meter were 61,79,and 38 respectively.According to preliminary estimation,the annual production of ergot in Changpei and Kuyan exceeded 60 tons.The ecological factors that favored the ergot epidemic were:(1)The presence of widely distributed susceptible host plants,(2)The presence of large amount of inoculum,(3)Severe winter that favors the venalization of ergot and wet summer that favors infection.Ergots were mostly formed from July 20 to August 10,with the middle part of August being the most suitable time for harvest. The total alkaloid contents of ergot varied with different hosts and decreased by the following order:Calamagrostis epigeios(0.577% estimated as ergotoxine),Clinelymus sibiricus(0.44%),Clinelymus dahurious(0.30—0.34%),Aneurolepidium dasystachys(0.13—0.15%),Aneurolepidium chinense(0.115%),rye(0.061—0.065%).The amount of total alkaloid of the ergots from same host species was rather stable and there seemed no significant differences among different localities.It appeared that there was no relationship between the size or color of ergot and the amount of alkaloid contents.Ergots of Aneurolepidium dasytachys,A.chinense,Clinelymus dahuricus,C.sibiricus and of rye were identified as Claviceps purpurea(Fr.)Tnl.and ergot of Calamagrostis epigeios was identified as C.microcephala(Wallr.)Tul.

1957年作者等在华北盛产野生麦角的地区张北及沽源进行了生态因子的调查,并在东北搜集了不同寄主上野生麦角的样本作含硷量的此较分析.张北及沽源禾本科植物对麦角病感染程度由重至轻的顺序为碱草、赖草、大麦草、紫穗大麦草、黑麦、偏穗冰草及披碱草,其平均感染百分数分别为68.48、60.97、60.00、50.00、42.00、14.00及6.59.此外拂子茅亦有轻度感染.大麦、小麦、燕麦及无芒雀麦均未发现感染.野生寄主植物中以赖草和碱草分布最广,其大片单独群落的密度每平方米平均分别为61茎和79茎,披碱草亦有大片羣落,平均密度每平方米为38茎,其他禾草的分布极为零星.估计张北及沽源麦角的年产量至少有12万市斤。张北及沽源盛产野生麦角的生态因子为:(1)有大量的感染寄主,(2)每年积累大量菌源,(3)长期寒冷的冬季,及6、7、8月阴雨气候.麦角形成最盛期为7月下旬至8月上旬,采收最合宜的时期为8月中旬.华北及东北地区各种寄主植物所产麦角含硷量差别很大,由高至低的顺序为:拂子茅(麦角硷计0.577%),老芒麦(0.44%),披碱草(0.30-0.34%),赖草(0.13-0.15%),碱草(0.115%),...

Securinine, an alkaloid from Securinega suffruticosa (Pall.) Rehd., has a stimulant action on the central nervous system. It is being used in many clinics of the USSR as a stimulant during the restorative period of acute poliomyelitis and in treatment of disturbances in motor and nervous functions. The present paper reports the use of active carbon for the isolation of sccurinine from the leaves of the plant as grown in Peking with seeds from the USSR. Ninety-four percent of the total alkaloids could be extracted by wetting the air-dried leaves for two hours with 0.3% H_2SO_4, and then percolating till the weight of percolate was 10 times that of the leaves. Adsorption of total alkaloids from the percolate by active carbon was best carried out at room temperature and pH 8—10.2. Chloroform was found to be a good desorbent. Raising the temperature increased the quantity desorbed. According to these results, a procedure for the isolation of securinine has been proposed, and small scale runs gave yields of 35.7—36.5% (based upon the total alkaloid content of the leaves) with m.p. 139.5—140.5℃.

1.証明自苏联引种的、在北京地区生长的一叶萩叶中含有一叶萩碱。 2.研究了影响活性炭吸附一叶萩生物碱的各种因素,发現当渗漉液pH在8.0—10.2时,活性炭吸附一叶萩生物碱的量最多;温度增高时,不利于吸附;渗漉液中生物碱含量越高,被吸附量也就越高;活性炭用量增加时,从同一浓度的渗漉液中吸附的生物碱量亦增加。 3.研究了从活性炭中洗脫一叶萩生物碱的适宜洗脫剂及洗脫条件,証明氯仿是比硫酸較为理想的洗脫剂。增加温度,可以增加生物碱的洗脫量。 4.根据一系列的研究結果,制訂了利用活性炭吸附法分离提取一叶萩碱的实驗室生产方法,并按此方法进行了实驗室小量試制。所得产品熔点为139.5—140.5℃,产率为35.7—36.5%(按原料中生物碱的含量計算)。
