Jatamansinol from Nardostachys jatamansi (D.Don) DC. Protects Aβ **Authors:** Anupama Kizhakke P, Shilpa Olakkaran, Antony Anet et al. **Journal:** Neurotoxicology (2022) **PMID:** 35247505 > Nardostachys jatamansi (D. Don) DC. is an essential plant used in Indian Ayurveda to treat neurological disorders, and it enhances memory. Its active phytochemical(s) responsible for neuroprotection is not yet studied. One of the neurological disorders, namely Alzheimer's disease (AD) causes dementia, is not having pharmacological strategies to effectively prevent the onset of AD, cure or reverse AD progression, and treat cognitive symptoms. Here is an attempt to analyze the neuroprotective effect of jatamansinol isolated from N. jatamansi against Aβ... **Keywords:** Aβ(42) protein, Drosophila, Memory, Nardostachys jatamansi, Oxidative stress, Pyranocoumarin #### 4. Jatamansinol from Nardostachys jatamansi Ameliorates Tau-Induced Neurotoxicity in Drosophila Alzheimer's Disease Model. **Authors:** Anupama Kizhakke Purayil, Antony Anet, Shilpa Olakkaran et al. **Journal:** Molecular neurobiology (2022) **PMID:** 35864434 > Nardostachys jatamansi has long been used to prepare Medhya [Rasayana](/reference/rasayana/) in traditional Indian Ayurveda medicine to treat neurological disorders and enhance memory. Jatamansinol from the N. jatamansi against Alzheimer's disease (AD) showed that it could be a multitargeted drug against AD. Drosophila is an ideal model organism for studying a progressive age-related neurodegenerative disease such as AD since its neuronal organizations and functioning are highly similar to that of humans. The current study investigates the neuroprotective properties of jatamansinol against Tau-induced neurotoxicity in the AD Drosophila model. Results indicate jatamansinol is not an antifeedant for larva and adult Drosophila. Lifespan, locomotor activity, learning and memory, Tau protein expression level, eye dege... **Keywords:** Drosophila, Memory, Nardostachys jatamansi, Oxidative stress, Pyranocoumarin, Tau protein #### 5. None **Authors:** Duan Congyan, Lin Weifang, Zhang Mingjie et al. **Journal:** Cells (2025) **PMID:** 40358168 > BACKGROUND: METHODS: Lipopolysaccharide(LPS)-induced BV-2 microglial cells and a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine/probenecid (MPTP/p)-induced male C57BL/6N mouse chronic model of Parkinson's disease were applied. RESULTS: Both NJ-1A and Nar could significantly suppress LPS-induced production of M1 pro-inflammatory factors or markers in microglia and could inhibit the glycolytic process and promote oxidative phosphorylation via the AKT/mTOR signaling pathway. Furthermore, they exhibited the capacity to attenuate chemokine release from activated microglia, consequently reducing T cell migration. In vivo experiments revealed that NJ-1A and Nar effectively inhibited microglial activation, diminished T cell infiltration, and mitigated the loss of tyrosine hydroxylase (TH)-positive ... **Keywords:** Nardostachys jatamansi, Parkinson’s disease, T cell infiltration, metabolic reprogramming, microglia, nardosinone, neuroinflammation #### 6.

Aromatherapy With Nardostachys Jatamansi DC. Essential Oil Targeting the MAOA Gene Regulates Cardiac Neural Remodeling and Amino Acid Metabolism to Alleviate Sleep Deprivation-Induced Myocardial Injury. **Authors:** Yang Hang, Li Yanzhen, Feng Lin et al. **Journal:** FASEB journal : official publication of the Federation of American Societies for Experimental Biology (2025) **PMID:** 40364704 > Sleep deprivation (SD) adversely affects cognition, as well as physical and mental health, and is closely linked to an increased risk of cardiovascular disease. The therapeutic efficacy and underlying mechanisms of aromatherapy with Nardostachys jatamansi DC. essential oil on SD-induced myocardial injury remain poorly understood. This study aimed to evaluate the therapeutic potential of aromatherapy with Nardostachys jatamansi DC. essential oil in mitigating SD-induced myocardial injury and to elucidate the associated mechanisms. Electroencephalogram (EEG) recordings and behavioral tests were employed to evaluate sleep and emotional responses. Serum myocardial injury markers were quantified using ELISA. Hematoxylin-eosin (H&E), Masson, and wheat germ agglutinin (WGA) staining were performe... **Keywords:** MAOA, amino acid metabolism, aromatherapy with Nardostachys jatamansi DC. essential oil, neural remodeling, sleep deprivation‐induced myocardial injury #### 8. Nardostachys jatamansi Ethanol Extract Ameliorates Aβ42 Cytotoxicity. **Authors:** Liu Quan Feng, Jeon Youngjae, Sung Yung-Wei et al. **Journal:** Biological & pharmaceutical bulletin (2018) **PMID:** 29398668 > The Nardostachys jatamansi DC (NJ) root has been used as a sedative or [analgesic](/reference/analgesic/) to treat neurological symptoms and pain in traditional Korean medicine. Here, we investigate the potential effects of NJ on Alzheimer's disease (AD) and reveal the molecular mechanism through which NJ exerts its effects. The neuroprotective effect of the NJ root ethanol extract against β amyloid (Aβ) toxicity was examined in vitro using a cell culture system and in vivo using a Drosophila AD model. The NJ extract and chlorogenic acid, a major component of NJ, inhibited Aβ-induced cell death in SH-SY5Y cells. Moreover, the NJ extract rescued the neurological phenotypes of the Aβ42-expressing flies (decreased survival and pupariation rate and a locomotor defect) and suppressed Aβ42-induced cell death in the brai... **Keywords:** Alzheimer’s disease, Drosophila, Nardostachys jatamansi, anti-inflammation, antioxidant, extracellular-signal-regulated kinase ## What do recent clinical trials show? - Jismi VS, Ramakrishna KK, Mehta UM and others 2025.
