| The history of Chinese medicine storage can be traced back thousands of years ago, Shang and Zhou dynasties, the ancients in the long-term medical practice gradually realize the importance of Chinese traditional medicine storage link, and gradually formed a unique Chinese medicine storage maintenance methods."Chinese goods logistics shelf on traditional Chinese medicine" thinks that storage time, storage methods, packaging methods, packaging materials and other aspects impact on the quality of traditional Chinese medicine have different degree. With the continuous expansion of the demand for traditional Chinese medicine, effectively solve the problem of the quality of Chinese medicine during storage shelf become a top priority, effectively guarantee the quality of traditional Chinese medicine circulation to ensure drug safety is of great significance.Ancient physicians based on the conservation of long-term storage of practical experience, summed up the medicine in storage easy to take the oil and discoloration is bitter almond, Huang Jing, wolfberry, chrysanthemum and bellflower those containing fatty oil. sugar and the unstable nature of many ingredients herbs,"weeping" also known as "take the oil" herbs contained in volatile oils. fats, carbohydrates, due to heat or moisture in the deterioration of the surface oily substance back to the soft, sticky, become darker in color, giving oil lost gas phenomenon. The Bitter almond comes from wild apricot Prunus armeniaca L.var.ansu Maxim.. The Siberian apricot Prunus sibirica L. northeast apricot Prunus mandshurica (Maxim.) Koehne or apricot Prunus armeniaca L. dried ripe seeds of Rosaceae. Summer harvest ripe fruit, remove the pulp and core-shell, remove the seeds, and dried. The first contained in the "Shen Nong’s Herbal Classic" is commonly used in traditional Chinese medicine, clinical for the prevention and treatment of cough, wheezing, chest full of phlegm, intestinal dry constipation the blood stasis and body fluid dry embolism, and so on. The bitter almond mainly produced in Liaoning. Inner Mongolia. Hebei. Shandong. Shaanxi, Shanxi, Gansu. Xinjiang and other places of China. Bitter almonds are rich in fatty oil. in the custody of the storage process due to heat or moisture can easily weeping, infestation, mildew, changed the original nature of the herbs, affecting its due effect [1]. Currently Chinese Herbal Medicine clinical application form traditional sliced and New Pieces two categories in which the new Pieces particles Pieces, Free fried Chinese Herbal Medicine (TCM formula particles), briquetting Pieces, Ultramicro, quantitative packaging Pieces, in order to the traditional Chinese medicine drug habit at the same time more convenient for patients medication to reduce the pollution of Pieces intermediate links, to ensure an accurate dose, this new Pieces of the bitter almond Pieces quantitative small package as an easy process oils herbs on behalf of its storage and maintenance study.The bitter almond Pieces in different packaging, storage conditions. Appearance, active ingredient content difference, this article mainly on the temperature (room temperature, cool, cool place), packaging materials (polyethylene plastic bags, aluminum foil composite film bag, kraft condensate film paper bag), oxygen presence or absence of the impact on the quality of Pieces of bitter almond, bitter almond Pieces by orthogonal test set different storage conservation methods, as a negative control without any treatment the bitter almond Pieces of observation bitter almond Pieces Appearance, water content, peroxide value and active ingredients, the best storage method compared0,3,6,12,18,24detection of two years, the analysis of the experimental data eventually come to such herbs and conditions. Compatibility test is to detect the interaction between packaging and herbs.The appearances of the bitter almond Pieces observe the color, shape, oil quality, the degree of adhesion, and vermin, mildew and so on. The bitter almond Pieces in summer is not only easy to take the deterioration of the oil, and very easy to infestation. According to the bitter almond slices of color, fragmentation, take the oil. the comprehensive evaluation of the degree of vermin.Testing the amygdalin content and peroxide value and moisture in deferent storage time of bitter almond Pieces, combined with herbs Appearance Evaluation bitter almond slices of quality. Testing the content of amygdalin in different storage time through High Performance Liquid Chromatography. a group of bitter almond slices is different content. Measured before storage bitter almond Pieces amygdalin content of2.690percent, the highest content of the conservation group after3months of2.600%,2.270%of the minimum group; six months after the highest group content of2.548%, minimum group of2.138%; December after the highest group content of2.660%,2.155%in the lowest group; eighteen months after the highest group content of2.580%,2.085%in the lowest group; two years after the highest group content of2.455%,2.070%in the lowest group.Measured before storage the bitter almond Pieces peroxide is0.005076,3months after the highest group content of the conservation0.01307. minimum group.006535; six months after the highest group content of0.004606. minimum group of0.002632: December after the highest group content of0.009212. minimum group of0.003948;18months after the highest group content of0.005598. minimum group0.002634:24months after the content of the highest group0.007245. lowest group of0.003293.Three factors is temperature (cold is better than a cool, cool better than room temperature), followed by oxygen (no oxygen is better than oxygen), and finally packaging materials (leather condensate film paper bag is better than polyethylene plastic bags, poly vinyl bag is better than aluminum foil composite film bag).Comparisons of compatibility test result:the type of packaging material for GC-MS analysis of the volatile solvent, acetone,1,6,6-trimethyl-cyclohexene as a blank polyethylene plastic unique, isopropanol. n-amyl alcohol, heptyl aldehyde,3-octanone, nonanol,3,5-dihydroxy toluene, linalool, undecene, octanoic acid,2,3-dihydro-benzofuran. cyclotetradecane, geranyl acetone, butyl hydroxyanisole ether (antioxidants BHA).17carbon alkyl, Ding mellow. Dihydroactinidiolide lactone,3-methyl-3-cyclohexen-1-OL for a blank leather condensate film paper bag is unique, with bitter almond Pieces18months cowhide condensate film paper bags and polyethylene plastic bag containing hydrocyanic acid, acetic acid, benzaldehyde, benzyl alcohol, longifolene,1-phenyl-1,2Propanedione-1-hydroxy-1-phenyl-2-acetone.Plastic packaging materials commonly used additives antioxidants BHT and BHA often used, and have a certain toxicity. BHT the three blank packaging materials contain, BHA only in the blank leather condensate film paper bag, but not detected in the herbs To compare the toxic and harmful residues in the three packaging materials, drawn polyethylene plastic bag is more suitable for the packaging of bitter almond Pieces.Comprehensive compatibility test, come to the conservation of the best storage method for the third group:polyethylene plastic vacuum packaging, cold place. |
