説明Gastrodin is extracted from the dry root of the orchid plant, Gastrodia elata. The source of raw materials is Yunnan Province. Traditional Chinese medicine Gastrodia elata (Gastrodia elata Bl.) is also known as Chi Jian, Ding Feng Cao, Shui Yang Yu, and so on, belonging to special symbiosis perennial herb of Orchidaceae and Armillaria mellea. The medicinal part is its tubers. It has sweet flavor and liver channel tropism and is neutral in nature. Traditional Chinese medicine believes that its main functions are to expel wind and relieve convulsion, calm the liver and suppress liver-yang, and expel wind evil and channel. There are 23 chemical ingredients extracted from Gastrodia elata, including gastrodin, gastrodia glycosides, vanilla alcohol, vanilla aldehyde, beta steroid valley alcohol, p-hydroxybenzoic acid, carrot glycosides, and so on, among which the highest content of single active ingredient is Gastrodia glycosides, namely, gastrodin

来歴It has been more than 30years since the chemical composition of Gastrodia elata was analyzed. It includes phenols, organic acids, sterols, and so on. At present, the studies of the composition of Gastrodia elata focus on the fingerprint, but the studies of gastrodin were centered on the activity. The studies showed that gastrodin has many pharmacological effects with safety and few side effects; moreover, it is not easy to accumulate in the body. Based on traditional medicinal experience of Gastrodia elata, gastrodin has been developed as a medicine for the treatment of insomnia, headaches, and other symptoms related to the functions and indications of Gastrodia elata. At present, many pharmaceutical factories in China have produced active pharmaceutical ingredients (API) and general preparation of gastrodin, such as Gastrodia tablet, Gastrodia capsule, and Gastrodia injection. To reduce the frequency of administration, the fluctuations of blood drug concentration, as well as side effects, some new dosage forms have been developed in recent years, such as Gastrodia dispersible tablets, Gastrodia sustained-release tablet, sustained-release pellets and osmotic pump tablets, etc. . Although gastrodin has been applied clinically, a lot of studies still need to be done to confirm the pharmacological effects of gastrodin. Recent studies found that other compositions of Gastrodia elata also showed rather excellent biological activity, suggesting that the study of Gastrodia elata and gastrodin needs further investigation.

使用Gastrodin up regulates heme oxygenase-1 expression through activation of p38 MAPK/Nrf2 signaling pathway thus protecting the SH-SY5Y cells from MPP+-induced oxidative cell death.
