摘要(Abstract):

[Objective]To compare the water content,ash and the whole extract of RADIX et RHIZOMA CYATHULAE CAPITATA,which is Yi Ethnic Minority Medicine Prescription Wo Si,RADIX et RHIZOMA CYATHULAE OFFICINALIS and RADIX et RHIZOMA ACHYRANTHIS BIDENTATAE.[Methods] The moisture was measured by the drying method in appendix Ⅸ H of Chinese Pharmacopoeia 2010,ash content was measured by appendix Ⅸ K and extract content by ⅩA. [Results] The experimental results showed that the water content was 4. 63%,4. 62% and 6. 53% of RADIX et RHIZOMA CYATHULAE CAPITATA,RADIX et RHIZOMA CYATHULAE OFFICINALIS and RADIX et RHIZOMA ACHYRANTHIS BIDENTATAE respectively; total ash content was 6. 88%,5. 65% and 6. 42% respectively; acid-insoluble content was 0. 53%,1. 00% and 0. 44% respectively; ether-soluble extract content was 0. 15%,0. 11% and 0. 18% respectively. The water soluble extract was 50. 91% and 59. 58% of RADIX et RHIZOMA CYATHULAE CAPITATA and RADIX et RHIZOMA CYATHULAE OFFICINALIS respectively; the ethanol soluble extract was 18. 83% and 9. 35% of RADIX et RHIZOMA CYATHULAE CAPITATA and RADIX et RHIZOMA ACHYRANTHIS BIDENTATAE respectively. For RADIX et RHIZOMA CYATHULAE CAPITATA,the content of water soluble extract of hot maceration was 64. 74%,higher than that of cold maceration; the content of ethanol soluble extract of hot maceration was 23. 16%,higher than that of cold maceration( 4. 84%); the extract of 50% ethanol was 61. 23%. [Conclusions]The water content and total ash of RADIX et RHIZOMA CYATHULAE OFFICINALIS and RADIX et RHIZOMA ACHYRANTHIS BIDENTATAE were meet the requirement of Chinese Pharmacopoeia 2010; the content of acid-insoluble ash was in order of RADIX et RHIZOMA CYATHULAE OFFICINALIS > RADIX et RHIZOMA CYATHULAE CAPITATA > RADIX et RHIZOMA ACHYRANTHIS BIDENTATAE; the content of water soluble extract of cold-maceration was as RADIX et RHIZOMA CYATHULAE CAPITATA≈RADIX et RHIZOMA CYATHULAE OFFICINALIS; the content of ethanol soluble extract of RADIX et RHIZOMA CYATHULAE CAPITATA was double of RADIX et RHIZOMA ACHYRANTHIS BIDENTATAE,and both of them were meet the requirement of Chinese Pharmacopoeia 2010( ≥5%); the content of volatile ether-extract of the three was similar; the content of water soluble extract was similar between RADIX et RHIZOMA CYATHULAE OFFICINALIS and RADIX et RHIZOMA CYATHULAE CAPITATA,both lower than the required content in Chinese Pharmacopoeia 2010( ≥65%); The best method of water soluble extract of RADIX et RHIZOMA CYATHULAE CAPITATA was the hot maceration,and the best method of ethanol soluble extract was hot maceration with 50% ethanol.
