Embodiment 1
[0032] refer to figure 1 , a raw material screening method for paclitaxel production, comprising the following steps:
[0033] S1: Prepare raw materials, prepare the whole Northeast yew tree, and then perform peeling treatment to distinguish the yew bark, branches and leaves;
[0034] S2: branch cutting, cutting the stripped bark and branches;
[0035] S3: Screening raw materials, removing unqualified bark and branches with insects or corrosion with a knife to prevent unqualified raw materials from polluting paclitaxel during the extraction process and affecting the normal efficacy of the drug;
[0036] S4: Clean the raw materials, put the raw materials to be processed in water, and then dry them naturally, then repeat the cleaning once, and then dry them again to prevent insect eggs or dust invisible to the naked eye from adhering to the raw materials, and then crush them later. The added ethanol will be polluted during the extraction, which will affect the normal reaction;...
Embodiment 2
[0044] refer to figure 1 , a raw material screening method for paclitaxel production, comprising the following steps:
[0045] S1: Prepare raw materials, prepare the whole Northeast yew tree, and then perform peeling treatment to distinguish the yew bark, branches and leaves;
[0046] S2: branch cutting, cutting the stripped bark and branches;
[0047] S3: Screening raw materials, removing unqualified bark and branches with insects or corrosion with a knife to prevent unqualified raw materials from polluting paclitaxel during the extraction process and affecting the normal efficacy of the drug;
[0048] S4: Clean the raw materials, put the raw materials to be processed in water, and then dry them naturally, then repeat the cleaning once, and then dry them again to prevent insect eggs or dust invisible to the naked eye from adhering to the raw materials, and then crush them later. The added ethanol will be polluted during the extraction, which will affect the normal reaction;...
Embodiment 3
[0056] refer to figure 1 , a raw material screening method for paclitaxel production, comprising the following steps:
[0057] S1: Prepare raw materials, prepare the whole Northeast yew tree, and then perform peeling treatment to distinguish the yew bark, branches and leaves;
[0058] S2: branch cutting, cutting the stripped bark and branches;
[0059] S3: Screening raw materials, removing unqualified bark and branches with insects or corrosion with a knife to prevent unqualified raw materials from polluting paclitaxel during the extraction process and affecting the normal efficacy of the drug;
[0060] S4: Clean the raw materials, put the raw materials to be processed in water, and then dry them naturally, then repeat the cleaning once, and then dry them again to prevent insect eggs or dust invisible to the naked eye from adhering to the raw materials, and then crush them later. The added ethanol will be polluted during the extraction, which will affect the normal reaction;...
