Processing Method of Pollen Typhae Charcoal Objective To determine the best processing technology of Pollen Typhae Charcoal. Methods The content of total flavonoids was determined by HPLC, and the processing technology of Pollen Typhae charcoal was studied by orthogonal design. The chromatographic conditions for the determination of total flavonoids were Waters Nove-Park C 18 column (150mm×3.9mm, 4 μ m); Mobile phase: methanol-tetrahydrofuran -0.05% trifluoroacetic acid aqueous solution (16 ∶ 24 ∶ 60); Volume flow: 0.8 ml/min; Column temperature: 30℃, detection wavelength: 360nm. Results The best processing technology of Pollen Typhae charcoal was that the temperature was controlled at 265 438 00℃ and fried for 8min. Conclusion The best processing technology of Pollen Typhae charcoal is reasonable.
Using orthogonal experimental design, taking tannin content and coagulation time as indicators, the effects of three key factors, namely baking temperature (a), baking time (b) and medicinal material thickness (c), on the quality of finished products were studied, and the process parameters were optimized. Results: Drying temperature (a) and medicinal material thickness (c) were the key factors affecting the preparation of pollen typhae charcoal, and the order of influence degree was A >；. C> B. conclusion: the best processing technology of pollen typhae charcoal is A2B2C3: the washed pollen typhae is laid flat on a 6 cm thick enamel plate, put in an oven, dried at 65438 050℃ for 5 min, and then taken out for cooling. The content of tannins and flavonoids, the main effective components of pollen typhae charcoal, increased during the frying process. By studying the pyrolysis characteristics of pollen typhae and its main effective components, it is known that the upper limit temperature of pollen typhae carbonization is 250℃ and the optimum processing temperature is 200℃.
The efficacy and function of Pollen Typhae charcoal can effectively inhibit tumor cells: Pollen Typhae charcoal can shorten coagulation time, prevent arterial bleeding, and is effective in treating liver cancer and pancreatic cancer caused by blood stasis. In addition, there is a folk prescription: it is often used with Cortex Moutan, Radix Curcumae, Poria and Radix et Rhizoma Rhei. 2. Pollen Typhae charcoal can cure hematuria caused by damp heat: Pollen Typhae charcoal with Pyrrosia, Sanguisorba officinalis, Amber, Cirsium japonicum, Notoginseng, etc. , fried in water. It is often used for bladder tumors with downward flow of damp heat and blood stasis blocking collaterals, with symptoms such as urinary retention and hematuria.
Pollen Typhae is a kind of pollen, which has certain effects of promoting blood circulation and removing blood stasis. However, patients with more bleeding will aggravate bleeding if they use blood circulation to remove blood stasis again. In order to stop bleeding, Pollen Typhae is often fried into charcoal, which can stop bleeding. Because Pollen Typhae itself has the function of promoting blood circulation, Pollen Typhae charcoal still retains some functions of promoting blood circulation. The reason why the function of promoting blood circulation is preserved is that Chinese medicine believes that bleeding is mostly caused by blood stasis, so it is most appropriate to use cattail pollen charcoal, which can not only treat the root cause of blood stasis, but also treat the underlying cause of bleeding, treating both the symptoms and the root causes.
