Problems solved by technology

[0010] However, the Chinese Pharmacopoeia only records that the "shady and cool place" does not exceed 20°C, and the requirement for "shady and cool and dry place" is relatively vague
Moreover, in practice, due to factors such as production, operation, and user unit storage conditions, management measures, and personnel quality, the factors affecting storage such as light, temperature, humidity, oxygen, and time have not been studied and controlled one by one; in addition, after storage There is no research on the quality of the medicinal materials, whether the storage conditions are appropriate, etc.
To sum up, the current status quo has led to large differences in the storage conditions of the mountain silver flower, and the quality of the medicinal materials is uneven.

Embodiment 1

[0059] Purchased 4 copies of Sanyinhua medicinal materials from 4 different stalls in the Chongqing Traditional Chinese Medicinal Materials Market, each 500g, all of which were identified as genuine Sanyinhua specified in the "Chinese Pharmacopoeia", marked as medicinal material 1, medicinal material 2, medicinal material 3 and medicinal material 4; Take another 1000g of Lonicerae pilosula flower buds collected in Xiushan County, Chongqing, steam them and dry them in a high-temperature dryer, and mark them as medicinal material 5.

[0060] Take 10 g of each portion of medicinal materials 1-5 as samples 1-5, and measure the content C1 of chlorogenic acid therein by HPLC method. The above samples were stored under different conditions. After storage, the content C1' of chlorogenic acid was measured respectively, and the evaluation value ΔC1 was calculated according to the formula ΔC1=1-C1' / C1. The storage conditions and measurement results are shown in Table 3 :

[0061] Table ...

Embodiment 2

[0066] Take 10 g of medicinal materials 1-5 in Example 1 as samples 6-10, and measure the content C2 of caffeic acid in them by HPLC method. The above samples were stored under different conditions. After storage, the content C2' of caffeic acid was measured respectively, and the evaluation value ΔC2 was calculated according to the formula ΔC2=1-C2 / C2'. The storage conditions and results are shown in Table 4:

[0067] Table 4 The content change of caffeic acid in L. japonicus under different temperatures

[0068]

[0069] It can be seen that the change of the content of caffeic acid can better evaluate the influence of temperature during storage on L. japonicus. When the evaluation value ΔC2≤0.20, it can be considered that the medicinal material is stored in a "shady place", such as storage below 20°C.

Embodiment 3

[0071] 10 g of medicinal materials 1 to 5 in Example 1 were taken as samples 11 to 15, and the content C3 of 3,5-dicaffeoylquinic acid was determined by HPLC. The above samples were stored under different conditions. After storage, the content C3' of 3,5-dicaffeoylquinic acid was measured respectively, and the evaluation value ΔC3 was calculated according to the formula ΔC3=1-C3' / C3. Storage conditions and results are shown in Table 5:

[0072] Table 5 Changes in the content of 3,5-dicaffeoylquinic acid in Flos Japonica under different vacuum conditions

[0073]

[0074] It can be seen that the change in the content of 3,5-dicaffeoylquinic acid can better evaluate the effect of oxygen on Linica japonica during storage. When the evaluation value ΔC3≤0.15, it can be considered that the medicinal material is stored in vacuum packaging.

Abstract

The invention brings forward a method for detecting storage condition of a lonicera macranthoides bud medicinal material. The method comprises the following steps: respectively measuring the color of lonicera macranthoides bud and content of six components of chlorogenic acid, caffeic acid, 3,5-dicaffeoylquinic acid, galuteolin, lonicera macranthoides saponins ethyl and Dipsacus asper wall saponins ethyl in lonicera confuse before and after the storage, combining changes of appearance colour and change degree of six components content before and after the storage, and evaluating whether the storage condition of the lonicera macranthoides bud is appropriate or not. The method is scientific and simple, and is in favor of guarantee of medicinal material quality, and fills the blank that no appropriate detection and evaluation method is existed for detecting storage condition of lonicera macranthoides bud.

Description

technical field [0001] The invention relates to the storage of the traditional Chinese medicine japonica japonica, in particular to a method for detecting storage conditions in the jasmine japonica. Background technique [0002] Mountain silver flower is a commonly used Chinese herbal medicine, which can be used to clear away heat and detoxify, and cool down wind-heat. In the "Chinese Pharmacopoeia", the source of mountain silver flower is: Lonicera macranthoides Hand.-Mazz., Lonicera macranthoides Hand.-Mazz., Lonicera macranthoides, Lonicera chinensis or Lonicera chinensis, or the dried flower buds with early blooming. [0003] Mountain silver flower has the characteristics of light weight, fragility, mildew and insect infestation, so how to store it is a very important issue. Various methods are reported in the prior art. Such as: [0004] CN201110175699.1 discloses a storage method for mountain silver flower tea: after packing mountain silver flower tea, put it in a s...
