附子是我国重要的中药,可炮制成附片入药。生附片有较大的毒性,许多人谈其毒色变,作者在安县参观附子种植基地时,对附子的毒性产生了浓厚兴趣,查阅相关资料发现,目前附子中提取主要毒性成分双酯型生物碱已经逐步用于戒毒、外用镇痛药物以及生物杀虫剂中,在四逆汤中也是直接入药。当地的加工厂也在少量加工生附片。生附片加工过程简单,直接切片高温干燥,但是褐变明显,表面易糊化,商品品质差,高温使双酯型生物碱易分解。使用化学防褐变剂处理后再低温干燥能抑制褐变,但带来外源化学物质残留,目前尚无更好的解决办法。
Aconite is an important Chinese medicine, can be prepared into a film into medicine. Health attached film has greater toxicity, many people talk about its toxic color change, the author visited the aconite planting base in Anxian, the toxicity of aconite had a keen interest in access to relevant information found that the aconite extract the main toxic component of the di-ester type Alkaloids have been gradually used in detoxification, topical analgesics and bio-insecticides, also directly into the medicine in Sini decoction. Local processing plants are also a small amount of processing attached. Raw sticks processing simple, direct high-temperature drying, but the browning obvious, the surface easily gelatinized, poor quality of goods, high temperature so that double-ester alkaloids easily broken down. The use of chemical anti-browning agents and then low-temperature drying can inhibit browning, but bring the exogenous chemical residues, there is no better solution.
