我们对含挥发油成分的中草药如何制成注射剂,在方法上作了试验;并以较简便的方法提取中草药中挥发油,作了初步探讨。目前常用的中草药,含挥发油较多品种有些已制成注射液.制备多数系采用中草药的原药材或饮片,反复蒸馏2—3次后,以每毫升蒸馏液相当于原中草药的克数,做为含量的标准。所以常因中草药本身质量的不同(产地及存放时间不同)而造成成品质量不能一致,影响疗效。依据中草药所含挥发油,可随水蒸汽蒸出,及
We made a preliminary study on how Chinese herbal medicines containing essential oils were made into injections and tested on the methods; we also extracted the essential oils from Chinese herbs with simpler methods. At present, the commonly used Chinese herbal medicines, some of which contain more volatile oils, have been made into injections. Most of the preparations use the original herbs or pieces of Chinese herbal medicines, and after repeated distillation 2-3 times, they are equivalent to the grams of the original Chinese herbal medicine per ml of distillate. For the content of the standard. Therefore, the quality of finished products cannot always be the same due to the different quality of Chinese herbal medicines (distinct origin and storage time), which affects the efficacy. According to the volatile oil contained in Chinese herbal medicine, it can be distilled out with steam, and
