The flowers are green, the first end is fractured, the fragments are hairy, about 2 mm long. Opener coronary drums, with a pretentious diliptical shape; malei 5, attached to the barrel wall, yellow; female 1, no hair. Taste, taste, taste。
[identify] (1) the powder is light yellow brown or yellow green. The gland is larger, the head is coneed, rectangular or slightly flat, 4-33 cells, two-four layers, 30-64-108 m in diameter, handle 1-5 cells, up to 700 m. There are two types of non-temporal hair: a thick wall with a single cell of up to 900 m long, with a thin or bubble-shaped snail on the surface, and a thin wall of non-tempered hair with a very long, bent or wrinkled surface. Thrysal acid crystals 6-45 m in diameter. A round or triangle of pollen granules, with a small, small surface mask and fine granular sculpture, with a 3-knot trench。
(2) take this product powder 0. 2g, plus 5 ml of methanol, and place it for 12 hours, filtered, and extract the filter as a solution for the test product. A green acid control product is also taken and methanol is added to a solution of 1 mg per 1 ml as a control solution. Following the thin layer chromatography (general rule 0502) test, extracts 10-20 ml from the specimen solution and 10 ml from the control solution, which is placed on the same silica gel h thin plate, with the upper layer solution of the acetate-methylate-water (7. 2. 5. 2. 5. 2. 5) as an extruder, carried out, removed, dryed and examined under ultraviolet light (365 nm). Fluorescent spots of the same colour in the chromatography for the test product, in positions corresponding to the control chromatography。
[specific spectrogram] measured according to the high-efficiency liquid chromatography method (general rule 0512)。
Spectrum conditions and system applicability tests, except for detection wavelengths of 240 nm, other same [dense determination] under phenol acid。
A reference to the preparation of a solution accurate is taken from a control of a green propane acid, defined in precise terms, plus methanol is made to a solution of 0. 40 mg per 1 ml。
Equivalent [dense determination] under phenol acid。
Precision extracts 2 μl of the reference solution and 2 μl of the solution for the test product, injects the liquid chromatograph, determines, and is obtained。
Seven characteristic peaks shall be present in the profile of the characteristics to be used for the test, corresponding to the peaks of the reference material, and the relative retention time of the peaks to the peaks of the reference material shall be calculated within the specified value of 10 per cent of the specified value, which shall be: 0. 91 (peak 1), 1. 00 [peak 2 (s)], 1. 17 (peak 3), 1. 38 (peak 4), 2. 43 (peak 5), 2. 81 (peak 6), 2. 93 (peak 7)。

The preparation of a control solution for the control of green acrylic acids, 3,5-o-d coffee acceleryl fluoride and 4,5-o-o-d coffee accommodated accompaniments, with a precise designation of 75 per cent of the brown volume bottles and a solution of 0. 28 mg, 0. 15 mg, 44 μg for each 1 ml。
Taking the powder of the product (over sift 4) is about 0. 5 g, defined in fine terms, with a cascading bottle containing a precise addition of 75% ml of methanol, weighing, ultrasound treatment (power 500 w, frequency 40khz) for 30 minutes, cooling, restating, filling the reduced weight with 75% methanol, smoothing, filtering, extracting leaching。
Precision extracts 2 μl of the control solution and 2 μl of the test solution, and the liquid chromatograph is injected to determine, i. E. To determine。
This product may not be less than 1. 5% green (c16h18o9) and the total volume of phenol acids may not be less than 3. 8% green (c16h18o9), 3,5-o-dcafazine acid (c25h24o12) and 4,5-o-d c25h24o12)。
The wood rhinoceros is determined by the high-efficiency liquid chromatography method (general rule 0512)。
The chromatography conditions and system applicability test uses phenylsilony key-based silicone as a filling agent (agilent zorbax sb-phenyl 4. 6 mm x 250 mm, 5 mm), acetylene as a flow a, 0. 5% ice-acrylate solution b as a flow b, with gradients removed as specified in the following table; detection wavelength is 350 nm. Theoretical plate numbers should not be less than 20,000 based on the peak of wood rhinoceros。
The preparation of a control solution the extraction of wood rhinoceros in a finely defined amount, plus 70% ethanol to a solution of 40 mg per 1 ml。
