Extractor for paeoniflorin and benzoic acid contents in red paeony root and white paeony root

Abstract

The invention discloses an extractor for paeoniflorin and benzoic acid contents in red paeony root and white paeony root, which comprises a scale, high performance liquid chromatographs, a connectingpartition, a sliding door, an analysis scale, a protective housing, an ultrasonic instrument, a temperature-controlled extraction and storage box, a thermal insulation handle, fixed blocks, adjustingscrews, a curved clamping rod, and an anti-corrosion protecting pad. The extractor has the advantages that: because pull rings are arranged on the high performance liquid chromatographs through fastening screws, the high performance liquid chromatographs can be drawn out when needed; because a scale which can independently carry out computation and reading to carry out operation control is arranged in the analysis scale, the situation that a material which needs to be weighed and analyzed cannot be analyzed is prevented; and because a type of high-strength stainless steel plate is welded to form the temperature-controlled extraction and storage box and a layer of thermal insulation layer is stuck in the temperature-controlled extraction and storage box by hot melt adhesive, the phenomenonof severe rusting can be prevented from occurring on the inside and outside of the temperature-controlled extraction and storage box to cause the damage of the extractor after a long time of use.

Description

technical field [0001] The invention relates to an extraction device, in particular to an extraction device for the content of paeoniflorin and benzoic acid in Radix Paeoniae Rubra and Radix Paeoniae Alba, and belongs to the technical field of extraction devices. Background technique [0002] Paeoniflorin is the main active ingredient of many commonly used Chinese medicinal materials such as Radix Paeoniae Alba, Radix Paeoniae Rubra and Cortex Moutan. It has significant analgesic, sedative, and anticonvulsant effects, can expand coronary arteries, increase coronary flow, resist acute myocardial ischemia, and lower blood pressure. , protect cerebral ischemia, anti-thrombosis, anti-platelet aggregation, anti-hyperlipidemia, and reverse hypotension. Bozhou, Anhui is the authentic production area of ​​Paeoniae Alba, and it is famous all over the country for its large output and good quality." [0003] Although the technology of the existing extracting devices of paeoniflorin and...

Problems solved by technology

[0003] Although the technology of the existing extracting devices of paeoniflorin and benzoic acid content in Radix Paeoniae Rubra and Radix Paeoniae Alba is relatively perfect, and the combination forms of the extraction devices of paeoniflorin and benzoic acid content in Radix Paeoniae Rubra and Radix Paeoniae Alba are various, But in general, there are still many common problems. First, the balance is only an ordinary balance, and there is no chip capable of high-speed calculation inside it, resulting in inaccurate weighing. Second, the existing red peony and white peony Most of the temperature-controlled extraction and storage boxes in the extraction device for the content of paeoniflorin and benzoic acid are iron products, which will lead to serious rusting inside and outside after long-term use, resulting in damage to the device. , The existing extraction devices for paeoniflorin and benzoic acid in Radix Paeoniae Rubra and Radix Paeoniae Alba are not equipped with analytical balances, which makes it impossible to analyze the materials that need to be weighed and analyzed, thus affecting the accuracy
