Angelica (Angelica archangelica) and Cognitive function: evidence and sources

The current study evaluated the anticonvulsant properties of ethanolic extracts from Morus alba, Angelica archangelica , Passiflora incarnata , and Valeriana officinalis using integrated phytochemical, in vivo, biochemical, and computational approaches. Phytochemical analysis by UHPLC-HRMS/MS revealed the presence of various bioactive compounds, notably flavonoids such as isorhamnetin, quercetin, and kaempferol. In an electroshock-induced seizure model, Morus alba extract (MAE, 100 mg/kg) demonstrated significant anticonvulsant effects, reducing both seizure duration and incidence, likely mediated by flavonoid interactions with GABA-A and 5-HT3A receptors, as suggested by target prediction and molecular docking analyses. The extracts of Angelica archangelica (AAE, 100 mg/kg) and Passiflora incarnata (PIE, 50 mg/kg) exhibited moderate, non-significant anticonvulsant activities. At the same time, Valeriana officinalis (VOE, 50 mg/kg) displayed considerable antioxidant and anti-inflammatory properties but limited seizure protection. All extracts significantly reduced brain inflammation markers (TNF-α) and enhanced antioxidant defenses, as indicated by total thiols. Molecular docking further supported the interaction of key phytochemicals, including naringenin and chlorogenic acid, with human and mouse 5-HT3A receptors. Overall, Morus alba extract exhibited promising therapeutic potential for epilepsy management, warranting further investigation into chronic seizure models and optimized dosing strategies.

Plant-derived molecules have enduring usefulness in treating diseases, and herbal drugs have emerged as a vital component of global therapeutic demand. Angelica archangelica L. (A. archangelica), commonly known as garden angelica, is an aromatic food plant used in culinary procedures as a flavoring agent. In the traditional medicine system, it is regarded as an "Angel plant" due to its miraculous curative power. This review aims to provide a comprehensive summary of the plant's taxonomic profile, ethnopharmacology, Phytochemistry, and pharmacological activities. Various in vivo and in vitro experiments have validated that the plant possesses broad pharmacological potential. The biological activities attributed to the plant include anti-anxiety activity, anti-convulsant activity, cognition enhancer, antiviral activity, cholinesterase inhibitory potential, antiinflammatory activity, gastroprotective activity, and radioprotective activity. The beneficial effects of the plant are credited to its bioactive components, that is, coumarins and volatile oils. The review summarizes the pharmacological activities of crude extract and its bioactive fractions and has also explored their target-oriented effects. This review will be of value in undertaking further investigations on the plant with regard to exploring mechanism-based pharmacological approaches on A. archangelica.

The plant Angelica archangelica, owing to its magnificent therapeutic effectiveness in folklore medicine system, has been regarded as an "angel plant." The current investigation was aimed to optimize extraction conditions of A. archangelica roots and to investigate in vivo role of optimized extract in fibromyalgia. Plant material (dried roots) was subjected to methanol extraction at variable temperature (40 to 60 °C) and time (12 to 36 hr) conditions as per two-factorial design strategy, and responses in terms of antioxidant activity were determined. The optimized extraction conditions were found to be temperature of 60 °C and time of 36 hr. HPLC fingerprinting indicated the presence of coumarins in extract. To induce fibromyalgia, the mice were administered reserpine at a dose of 0.5 mg/kg. Mice were orally treated with 100, 200, and 400 mg/kg extract, and magnitude of fibromyalgia was quantified. In comparison to reserpine group, the extract treatment attenuated pain as shown by significant increase in paw withdrawal threshold against mechanical stimuli (P < 0.05), improved motor ability indicated by increase in fall-off time in inclined plane test (P < 0.05), improved locomotion indicated by increased square crossings in open field test (P < 0.05), and improved cognition as shown by significant reduction in time to reach platform in Morris water maze test and passive avoidance task test (P < 0.05). Extract treatment significantly halted reserpine-induced rise in serum cytokine level (P < 0.05) and brain oxidative stress (P < 0.05). Angelica archangelica extract exerted its beneficial effects in fibromyalgia possibly through the attenuation of oxidative stress-mediated inflammatory cascade. PRACTICAL APPLICATION: Leads from natural products have become an integral part of drug designing processes and have high acceptability due to their better tolerance. The optimization of extraction conditions of plant yields better results and could reduce the processing time, thus increasing its industrial value.
