Embodiment 1

[0022] Different solvent experiments

[0023] The dried Phellodendron officinalis was crushed through a 60-80 mesh sieve, 12 parts of 1.0 g dried Phellodendron officinalis powder were accurately weighed, placed in plastic sealed bags, randomly divided into 4 groups, 3 bags in each group, and 40 ml of water, 70% Ethanol, 70% methanol, 70% acetone, sealed and soaked for 24 hours. Then put it into the ultra-high pressure equipment, pressurize 200 MPa for leaching, extract at 30°C, hold the pressure for 3 min, release the pressure, and after centrifugal filtration, take 1 ml of the extract into a 10 ml volumetric flask, and distill it to volume. The content of berberine and palmatine was determined by HPLC-DAD method. HPLC conditions: Daiso ODS-BP column (5 μm, 4.6 mm × 250 mm); mobile phase: acetonitrile (A)—0.7% phosphoric acid solution (B); gradient elution conditions: 0-5 min, B: 75 %; 5-35 min, B: 60%; column temperature: 30°C; flow rate: 1 ml / min; detection wavelength: 345...

Abstract

The invention discloses an extraction method and a detection method for berberine and palmatine in cortex phellodendri chinensis. The extraction method comprises the following steps: crushing dried cortex phellodendri chinensis and carrying out sieving with a 60-mesh to 80-mesh sieve; adding obtained powder in to a solvent according to a solid-liquid mass ratio of 1:10 to 1: 50; soaking the powder for 24 h at a normal temperature after mixing and sealing; placing an obtained mixture in a high pressure vessel and applying a pressure of 100 to 500 MPa at a temperature of 20 to 60 DEG C for extraction, with holdup time being 1 to 5 min; and centrifuging an extractive after pressure relief, taking a supernatant and carrying out filtration so as to obtain an extract of cortex phellodendri chinensis; wherein the solvent is selected from the group consisting of water, ethanol with a concentration of 10 to 90%, methanol with a concentration of 70% and acetone with a concentration of 70%. The supernatant is subjected to HPLC quantitative analysis so as to realize detection. According to the invention, structural changes and loss and reduction in physiological activity of an effective constituent caused by heat effects are avoided, extraction time is short and consumes a small amount of energy, and the detection method is simple, accurate and rapid and has high compactness and good repeatability.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to the extraction of effective components in Phellodendron officinalis, in particular to a method for extracting berberine and palmatine from Phellodendron officinalis by using ultra-high pressure. Background technique [0002] Phellodendron Phellodendri is a commonly used Chinese medicinal material, which has the functions of clearing away heat and dampness, purging fire and removing steam, detoxifying and treating sores. Phellodendron cortex used clinically in traditional Chinese medicine includes two varieties, "Guan Phellodendron" and "Chuan Phellodendron", and the medicinal parts are all dry bark. Before the 2005 edition of "Chinese Pharmacopoeia", Guan Phellodendron and Chuan Phellodendron were recorded together as "Phelloderma Phellodendron". Cortex Phellodendri Phellodendron amurense Rupr. The dry bark of the plant has antibacterial, antipyretic, anti-inflammatory, anti-ca...
