Parishin C is a phenolic glycoside and a major component of G. elata. It prevents inhibition of NMDA receptor (NMDAR) currents induced by amyloid-β (1-42) (Aβ42) in rat hippocampal neurons when used at a concentration of 2 μM. In vivo, parishin C (20 mg/kg) prevents Aβ42-induced inhibition of long-term potentiation (LTP) in rats. Parishin is an agonist of the serotonin (5-HT) receptor subtype 5-HT1A (Ki = 1.54 nM; EC50 = 34 nM for [35S]GTPγS binding) that reverses phencyclidine-induced increases in immobility time in the forced swim test, phencyclidine-induced decreases in interaction time in the social interaction test, and phencyclidine-induced impairments in visual recognition of a novel object in mice.

Parishin C's prevention of Aβ 1-42-induced inhibition of long-term potentiation is related to NMDA receptors
Acta Pharm Sin B 2016 May;6(3):189-97.PMID:27175329DOI:10.1016/j.apsb.2016.03.009.
The rhizome of Gastrodia elata (GE), a herb medicine, has been used for treatment of neuronal disorders in Eastern Asia for hundreds of years. Parishin C is a major ingredient of GE. In this study, the i.c.v. injection of soluble Aβ 1-42 oligomers model of LTP injury was used. We investigated the effects of Parishin C on the improvement of LTP in soluble Aβ 1-42 oligomer-injected rats and the underlying electrophysiological mechanisms. Parishin C (i.p. or i.c.v.) significantly ameliorated LTP impairment induced by i.c.v. injection of soluble Aβ 1-42 oligomers. In cultured hippocampal neurons, soluble Aβ 1-42 oligomers significantly inhibited NMDAR currents while not affecting AMPAR currents and voltage-dependent currents. Pretreatment with Parishin C protected NMDA receptor currents from the damage induced by Aβ. In summary, Parishin C improved LTP deficits induced by soluble Aβ 1-42 oligomers. The protection by Parishin C against Aβ-induced LTP damage might be related to NMDA receptors.
Parishin C attenuates phencyclidine-induced schizophrenia-like psychosis in mice: involvements of 5-HT1A receptor
J Pharmacol Sci 2010;113(4):404-8.PMID:20644336DOI:10.1254/jphs.10040sc.
Parishin C, a major component of Gastrodia elata BLUME (GE), was purified from GE. Because GE modulates the serotonergic system and the 5-HT(1A) receptor is an important therapeutic target of schizophrenia, we examined whether Parishin C affects phencyclidine-induced abnormal behaviors in mice. Phencyclidine-induced abnormal behaviors were significantly ameliorated by Parishin C. These effects were reversed by WAY 100635, a 5HT(1A)-receptor antagonist. Consistently, Parishin C showed high affinity at 5-HT(1A) receptor as well as a 5-HT(1A)-agonist activity in a 8-OH-DPAT-stimulated [(35)S]GTP-gammaS binding assay. Our results suggest that the antipsychotic effects of Parishin C require activation of 5-HT(1A) receptors.
Ameliorative Effect of Parishin C Against Cerebral Ischemia-Induced Brain Tissue Injury by Reducing Oxidative Stress and Inflammatory Responses in Rat Model
Neuropsychiatr Dis Treat 2021 Jun 4;17:1811-1823.PMID:34113111DOI:10.2147/NDT.S309065.
Background: Gastrodia elata Blume (Orchidaceae) is a widely used traditional Chinese herbal medicine in the clinical practice of China, to treat nervous headache, convulsions, dizziness, neurasthenia, and so on. Parishin C (Par C), one of the major bioactive components of Gastrodia elata Blume, is known to exert many different biological activities, including antipsychotic and neuroprotective effects. However, there is little research about its neuroprotective effect in an ischemic stroke model. The objective of the present study is thus to investigate the neuroprotective effects of Par C against cerebral ischemia damage. Methods: Rats were pretreated with Par C (25, 50, or 100 mg/kg/day, i.p.) for 21 days, then subjected to 2 h of middle cerebral artery occlusion (MCAO) and 22 h of reperfusion. Neurological deficient scores, brain water content, histopathology, TCC staining were performed to assess the neuroprotective effects of Par C. Meanwhile, the oxidative stress, inflammation and apoptosis-related markers of brain tissue were evaluated by corresponding assay kits. Besides, the antioxidant and pro-inflammatory expression was measured by real-time quantification PCR (RT-qPCR). Results: Our findings indicated that the pre-treatment with Par C improved nerve function, suppressed oxidative stress, and pro-inflammatory factors release in rats with cerebral ischemia damage. Besides, Par C significantly increased antioxidant expression and declined pro-inflammatory cytokines expression. Conclusion: Par C is shown to exert neuroprotective effects partly via inhibiting oxidative stress and inflammation in a rat model of MCAO.
An Optimized and Sensitive Pharmacokinetic Quantitative Method of Investigating Gastrodin, Parishin, and Parishin B, C and E in Beagle Dog Plasma using LC-MS/MS after Intragastric Administration of Tall Gastrodia Capsules
Molecules 2017 Nov 10;22(11):1938.PMID:29125575DOI:10.3390/molecules22111938.
Gastrodia elata Blume, called Tianma in China, has been widely used to treat headaches, convulsions and epilepsy for thousands of years. In the present study, a series of optimizations were employed to develop a rapid, sensitive, and reliable high-performance liquid chromatography-triple quadrupole mass spectrometry method, which was then used for the simultaneous determination of gastrodin, parishin, parishin B, Parishin C and parishin E in beagle dog plasma after intragastric administration of tall Gastrodia capsules (Tianma brand). The chromatographic separation was achieved on a C18 column with gradient elution by using a mixture of 0.4% formic acid aqueous solution and acetonitrile as the mobile phase at a flow rate of 0.15 mL/min. A tandem mass spectrometric detection was conducted using multiple-reaction monitoring (MRM) via electrospray ionization (ESI) source in negative ionization mode. Samples were pre-treated by a single-step protein precipitation with methanol, and bergenin was used as internal standard (IS). Under the optimized conditions, the lower limit of quantification (LLOQ) was 0.10 ng/mL for gastrodin, 0.40 ng/mL for parishin B, 0.02 ng/mL for parishin E and 0.20 ng/mL for parishin and Parishin C, all of which previously were the highest levels of sensitivity. The methods were optimized for selectivity, calibration curves, accuracy and precision. Extraction recoveries, matrix effects and stability were within acceptable ranges. Pharmacokinetic parameters of the tested substances were also quantitatively determined. Finally, a possible metabolic pathway was induced based on correlations obtained from quantitative and qualitative data analysis in vivo.
Pharmacokinetic and tissue distributions study of adenosine, 4-hydroxybenzyl alcohol and Parishin C from Gastrodia elata extract in rats
Pak J Pharm Sci 2018 Sep;31(5(Supplementary)):2053-2060.PMID:30393212doi
The plant Gastrodia elata is a type of the orchid plant Gastrodia elata Bl. which contains glycosides, phenols, polysaccharides, sterols, and organic acids and a variety of active ingredients are proved to have certain pharmacological activities. To understand the process in the body of Gastridua elata, we used HPLC to study pharmacokinetics and tissue distributions of adenosine, 4-hydroxybenzyl alcohol and Parishin C in rats. The results showed that the three ingredients could be detected in plasma and different organizations at various time points. There was no significant difference in systemic clearance at three ingredients and it may be show that the three ingredients distributed (0.475±0.025, 0.518±0.033, 0.699±0.051) quickly and eliminated (5.37±0.87, 4.54±0.69, 5.34±0.82) slowly in plasma. There was the highest content of adenosine in spleen, followed by liver and lung. The highest content of 4-hydroxybenzylacohol in liver, and was higher in spleen. Parishin C was highest in heart, followed by liver and spleen. It is obvious that the contents of three ingredients are all higher in liver. The trends of the three ingredients' contents in G. rhizome extract were consistent with the contents in the plasma after intravenous administration.
