Preparation and Quality Evaluation of Salvianolic Acids and Tanshinones Dry Powder Inhalation

Salvianolic acids and tanshinones both exhibit efficacy in treating idiopathic pulmonary fibrosis (IPF), but their formulation limits their clinical use. This study aimed to prepare the salvianolic acids and tanshinones dry powder for inhalation (SPI) to achieve pulmonary delivery for the treatment of IPF. The variable quantities of salvianolic acids and tanshinones composite powder were optimized using the central composite design-response surface method. Different carriers with various drug-carrier ratios were optimized to prepare SPI. The final optimized formulation of SPI was as follows: InhaLac 230^® was selected as the carrier with drug:carrier = 1:6, and the milled lactose InhaLac 400^® was added at 5%. The developed SPI characterized with an angle of repose 52.46 ± 1.04°, Carr's index of 34.00 ± 0.50% and showed high lung deposition in vitro, indicating the potential of pulmonary delivery for the treatment of IPF.     

生物和非生物诱导子对丹参毛状根培养生产丹参酮的影响

目的比较几种生物诱导子〔酵母提取物(yeast ex tract)、寡半乳糖醛酸(o ligoga lacturon ides)、真菌诱导子(funga l e lic itor)〕和非生物诱导子(A g 、Co2 和α-氨基异丁酸)对丹参毛状根培养生产丹参酮的影响。方法高效液相色谱法测定3种丹参酮。结果生物诱导子一般都能有效地提高丹参酮的产量,不同诱导子的诱导效果之间存在差别。最高的丹参酮产量由100μg/mL的真菌诱导子获得,是对照组产量(0.42 m g/g)的4.7倍。非生物诱导子对丹参酮的诱导能力相对生物诱导子较差,其中50μm o l/L Co2 获得了最高的丹参酮产量(1.75 m g/g),是对照组产量的4.1倍。生物诱导子和非生物诱导子表现出了一定的诱导选择性。所有的生物诱导子都显著提高了隐丹参酮的量而所有的非生物诱导子都选择性地提高了丹参酮Ⅰ的量。并且在大部分情况下,添加的诱导子都没有对丹参毛状根的生长造成明显的抑制作用。结论在丹参毛状根培养中添加不同的生物和非生物诱导子都可以选择性地提高丹参酮的积累,并且不影响毛状根的生长。     

生物与非生物诱导子协同作用对丹参毛状根培养生产丹参酮的影响

目的:考察生物诱导子yeast extract和不同非生物诱导子(Ag⁺,Co²⁺,α-氨基异丁酸)协同作用对丹参毛状根培养生产丹参酮的影响。方法:在丹参毛状根培养基中添加不同诱导子及诱导子组合,利用高效液相色谱法检测3种主要丹参酮(隐丹参酮、丹参酮Ⅰ和丹参酮ⅡA)的含量。结果:yeast extract与各非生物诱导子在不同浓度下的组合对丹参酮Ⅰ和丹参酮ⅡA都发挥了较好的协同诱导作用,而对隐丹参酮的协同诱导效果不显著。其中,yeast extract和Ag+(300μmol.L^-1)协同作用获得了最高的丹参酮Ⅰ产量,是对照组含量的13.9倍,诱导协同作用系数为3.0。yeast extract和Co²⁺(100μmol.L^-1)协同作用获得了最高的丹参酮ⅡA产量,是对照组含量的14.5倍,协同作用系数为2.1。yeast extract和α-氨基异丁酸(200μmol.L^-1)的组合是唯一一个比单个诱导子更有效地提高了隐丹参酮产量的组合,隐丹参酮的产量达到1.28 mg.g^-1,是对照组含量的30.3倍,诱导协同作用系数为1.3。结论:利用生物诱导子yeast extract和不同的非生物诱导子进行协同作用,其诱导效果比单独使用某一种诱导子的诱导效果更好,这种相互作用可以更有效地促进次生代谢产物的合成。     

丹参冠瘿组织的生长和总丹参酮的积累动态

AIM　To determine the dynamics of growth and total tanshinones accumulation in crown gall cultures of Salvia miltiorrhiza in MS and 67-V liquid media. METHODS　Fresh, dry weight and total tanshinones yields in the cultures and in the medium were determined every 5 days in crown gall suspension cultures. RESULTS　In MS medium, the logarithmic growth phase of crown gall cultures in S.miltiorrhiza was from the 5th to 30th days, and the stationary growth phase was from the 30th to 35th days. From the 25th to 30th days, physiological activity of crown gall cultures was higher and their growth was better. However, in 67-V medium, the logarithmic growth phase of crown gall cultures was from the 10th to 25th days, and the stationary growth phase was from the 25th to 35th days. Total tanshinones were largely accumulated in the cultures and in the medium after 25 days. The total tanshinones yield (60 mg.L^-1) was reached at the 35th day. CONCLUSION　Knowing the regularity of the growth and total tanshinones accumulation in crown gall cultures of S.miltiorrhiza will be helpful to take proper regulative measures in order to obtain the maximum total tanshinones yield.
