Bacopa monnieri (L.) Pennell - syn.Gratiola monnieria L.; Lysimachia monnieri L. - Plantaginaceae
brahmi, bacopa, water hyssop, herb of grace, Kleines Fettblatt

Succuleent creeping herb, native to India and Southeast Asia; leaves sessile, entire, oblong-oblanceolate; flowers axillary, white, blue, or purple; fruit a narrowly ovoid capsule; seeds yellow-brown.

„Bacopa has been used in traditional Ayurvedic treatment for epilepsy and asthma.“

The putative bioactive component, Bacoside A, was found to be a mixture of saponins with bacoside A3 (0.1-0.8%), bacopaside II (0.1-0-6%), jujubogenin isomer of bacopasaponin C (0.05-0.7%) and bacopasaponin C (0.05-0.4%) as major constituents. Two common flavonoids, luteolin and apigenin, were also present in all samples.

„Several Bacopa samples (plant materials, extracts and commercial formulations) were successfully analyzed. Major bacopasaponins were bacosides A3 (3), bacopaside II (4), bacopaside I (5), bacopaside X (6), bacopasaponin C (7), bacopaside N2 (9) and the minor components were bacopasaponin F (1), bacopasaponin E (2), bacopaside N1 (8) bacopaside III (10), bacopaside IV (11) and bacopaside V (12). The total saponin content in the samples, plant materials and extracts varied from 5.1 to 22.17% and 1.47 to 66.03 mg/capsule or tablet in the commercial formulations.“

„There is some evidence to suggest that Bacopa improves memory free recall with evidence for enhancement in other cognitive abilities currently lacking perhaps due to inconsistent measures employed by studies across these cognitive domains.“

„A search strategy was implemented to capture clinical studies into the neurocognitive effects of modafinil, Ginseng and Bacopa. Studies undertaken on healthy human subjects using a double-blind, placebo-controlled design were included. For each study where appropriate data were included, effect sizes (Cohen's d) were calculated for measures showing significant positive and negative effects of treatment over placebo. The highest effect sizes for cognitive outcomes were 0.77 for modafinil (visuospatial memory accuracy), 0.86 for Ginseng (simple reaction time) and 0.95 for Bacopa (delayed word recall). These data confirm that neurocognitive enhancement from well characterized nutraceuticals can produce cognition enhancing effects of similar magnitude to those from pharmaceutical interventions.“

Using oxygen- and glucose-deprivation (OGD)-induced hippocampal cell damage as an in vitro model of ischemia, bacopaside I (25 μM) exhibited potent neuroprotective effects against OGD-induced neuronal cell damage. „OGD caused necrosis and apoptosis and… bacopaside I attenuated the effects of OGD. The neuroprotective effects of bacopaside I were blocked by the PKC inhibitor Ro-31-8220 and PI3K inhibitor LY294002, but not by the ERK inhibitor U0126.“
