Description
Technical Field
The invention relates to the field of traditional Chinese medicine variety analysis, in particular to a high performance liquid chromatography identification method for gastrodia elata.
Background
Gastrodia elata is one of the commonly used famous and precious traditional Chinese medicines, also known as red arrow, sedge, shencao and the like, is a dry tuber of Gastrodia elata Bl. Tianma is neutral in nature and sweet in taste, and enters liver meridian; has effects in calming endogenous wind, relieving spasm, suppressing liver yang, dispelling pathogenic wind, and dredging collaterals; can be used for treating hyperactivity of liver-yang, hyperactivity of liver-wind, apoplexy, and arthralgia due to wind-dampness. Gastrodia elata is a perennial parasitic plant, and takes its host Armillaria mellea as a nutrient source. The chemical components of gastrodia elata are various, and mainly comprise phenol components represented by gastrodine (gastrodine) and p-hydroxybenzyl alcohol, barcinoside components formed by condensing gastrodine and citric acid, sterols such as beta-sitosterol, amino acids such as lysine and polysaccharides, and various chemical components. Rhizoma gastrodiae is known as a wind-treating psychotropic drug, is commonly used for treating diseases such as infantile convulsion, epilepsy and convulsion, tetanus, headache and dizziness, limb paralysis, limb numbness, rheumatism and arthralgia and the like in clinical traditional Chinese medicine, has wide pharmacological action and relates to a plurality of systems such as a central nervous system, a cardiovascular system, an immune system and the like. Modern pharmacological research shows that the gastrodia elata also has pharmacological activities of resisting cerebral ischemia, AD, oxidation, aging, inflammation, neuroprotection, immunity enhancement and the like.
The gastrodia elata is used as a traditional rare Chinese medicinal material in China, is widely applied in the clinical field of traditional Chinese medicine, and is an important raw material medicine of more than ten common Chinese patent medicines such as gastrodia elata and polygonum multiflorum tablets, gastrodia elata and uncaria granules, large ligusticum wallichii tablets and the like. Common gastrodia elata medicinal materials mainly comprise gastrodia elata, red gastrodia elata and Wuhong hybrid gastrodia elata, the character difference of underground tubers of different varieties of gastrodia elata is small, after the gastrodia elata medicinal material commodities are processed, the character difference of different varieties of gastrodia elata medicinal materials is not obvious and difficult to distinguish, and great difficulty is brought to distinguishing and identifying different varieties of gastrodia elata medicinal materials. Among various gastrodia elata medicinal materials, the genuine medicinal material gastrodia elata is expensive and has obvious price difference with the red gastrodia elata and the black red gastrodia elata, so that the phenomenon that the red gastrodia elata and the black red gastrodia elata are used for being sold as the black gastrodia elata is caused, market circulation is influenced, and the quality of related products is reduced.
The traditional method distinguishes and determines the varieties of the gastrodia elata through the color of the rachis, and the method is strong in experience, low in standardization degree and difficult to master. The traditional method for identifying gastrodia elata, gastrodia elata and gastrodia elata mostly adopts a capillary electrophoresis technology, a nuclear magnetic resonance spectroscopy technology and an electron bombardment ion source-mass spectrometry combined technology, and the detection technologies are complex and complicated to operate. The traditional high performance liquid chromatography technology is adopted to detect the gastrodia elata, the gastrodia elata and the gastrodia elata, although the detection is quick and convenient, the different components of the gastrodia elata and other gastrodia elata cannot be found, and the gastrodia elata cannot be identified through index chemical components (such as gastrodin, balansin A, balansin B, balansin C, balansin E, hydroxybenzaldehyde and the like) of the gastrodia elata.
Disclosure of Invention

The HPLC-UV characteristic spectrum of Gastrodia elata Blume is shown in figure 1, wherein P3 is gastrodin; p6 is the balsamoside E; p9 is the balsamoside B; p11 is balaneboside a. The HPLC-UV characteristic spectrum of 15 batches of gastrodia elata medicinal materials is shown in figure 2.
The HPLC-UV characteristic spectrum of rhizoma Gastrodiae is shown in figure 3, wherein P3 is gastrodine; p6 is the Balison glycoside E; p9 is the balsamoside B; p11 is balaneboside a. The HPLC-UV characteristic spectrum of 15 batches of the gastrodia elata medicinal material is shown in figure 4.

As shown in fig. 7, by comparing the HPLC fingerprints of gastrodia elata, gastrodia elata and gastrodia elata, we found 3 different components, which are labeled as a, b and c, respectively. The chemical components a, b and c are absent in the gastrodia elata, and the gastrodia elata both contain the 3 components, wherein the content of the 3 components in the gastrodia elata is slightly higher than that of the gastrodia elata.
To further characterize these 3 differential components, the experiment used a tandem Agilent MSD-iQ single quadrupole mass spectrometer to acquire LC-MS data in positive ion mode in SCAN mode, and the results are shown in fig. 8, where the chromatographic peak a (m/z 848, c) was extracted by comparing the Total Ion Current (TIC) chromatogram and the 290nm Ultraviolet (UV) chromatogram to obtain a chromatographic peak a (m/z 848, c) 41 H 53 NO 18 )，b(m/z 802，C 40 H 51 NO 16 ) And c (m/z 772,C) 39 H 49 NO 15 ). Comparing the retention time and the relative retention time of the 3 chromatographic peaks with obvious missing characteristics, wherein the distribution ranges of the retention time of chromatographic peaks a, b and c are respectively 16.94-17.01 min, 19.79-19.86 min and 20.83-20.88 min; by P9 chromatographyThe peak (the balaneboside B) is used as a reference, and the relative retention time distribution ranges of chromatographic peaks a, B and c are 1.18-1.21, 1.39-1.42 and 1.47-1.49 respectively.
In summary, when the high performance liquid chromatography identification method for gastrodia elata is adopted to analyze a gastrodia elata sample, if chromatographic peaks of compounds a, b and c are found in an obtained liquid chromatogram, and within the range of the retention time and the relative retention time, the gastrodia elata sample is red gastrodia elata or black red gastrodia elata, and if the chromatographic peaks of a, b and c are not found in the liquid chromatogram, the gastrodia elata is black.
