(2001) reported significant improvement in verbal learning, memory consolidation, and faster information processing following bacopa administration (containing 55% combined bacosides) for 12 weeks at a dose of 300 mg daily in a double-blind, placebo-controlled study in healthy volunteers (age 18–60 years, n=46; Stough et al., 2001). The flowers have both pollen -bearing and ovule -bearing parts, and usually zygomorphic (i.e., bilaterally symmetrical ). P. kurroa commonly known as kutki and belonging to the family Scrophulariaceae, is a herb native to the Himalayan regions of India, Pakistan, and Nepal. Scrophulariaceae family includes 62 genera and about 1830 known species.. Click on the photo or the name of the plant for which you wish to see further information. The Scrophulariaceae family is a diverse botanical family, also known as figwort. Some members of these families have been investigated for their neuroprotective activities through various in vitro and in vivo methods.

A methine doublet of doublets (J = 3.7, 7.4 Hz) was found at 5.61 ppm, and the methine coupling with the methyl doublet (J = 7 Hz) was located at 3.59 ppm. Root zone heating has been shown to increase Calceolaria plant shoot fresh and dry weights and flower number with no effect on days to anthesis (White and Biernbaum, 1984b). In another randomized, double-blind, placebo-controlled trial of 54 elderly participants over 70 years of age without clinical signs of dementia, bacopa treatment enhanced auditory verbal learning test results and delayed word-recall memory scores relative to placebo (Calabrese et al., 2008). Water relations were also not affected by the heating system as measured by stomatal resistance or water potential (Panter and Hanan, 1987). Studies have also documented its potential as a therapeutic candidate for mental illness and epilepsy. Therefore the methine protons were deduced to be anti to each other, and rhexifoline has the stereochemistry shown in 23 (35). Species in Diocirea. Picroliv has been found to possess active hepatoprotective activity against different hepatotoxins (Saraswat et al., 1999). Springer. The stereochemistry of rhexifoline was deduced from NOE studies, in which irradiation of H-5 enhanced H-6β at 2.03 ppm, but not H-6α at 2.43 ppm. Daylength had little effect during the cool temperature treatment. The neuronal dendritic growth-stimulating property of bacopa has also been reported, which may be responsible for its memory-enhancing effects (Vollala et al., 2011). Bacopa and its constituents (bacosides) prevented behavioral impairment and GABA-receptor dysfunction in epileptic rats (Mathew et al., 2010a, 2010b, 2010c, 2011, 2012). Studies have shown that the methanolic extract of P. kurroa rhizomes was effective in reducing the indomethacin-induced gastric ulceration in mice by reducing oxidative stress; promoting mucin secretion and prostaglandin synthesis; and augmenting expressions of cyclooxygenase enzymes and growth factors (Banerjee et al., 2008). Australia: 17 genera, all States. In a double-blind, placebo-controlled trial of 38 healthy volunteers (ages 18–60 years), a single dose of 300 mg of Bacopa monnieri extract (containing 55% combined bacosides A and B) did not cause any significant change in cognitive function at two hours (Nathan et al., 2001). 44.2). Gross lesions include widespread hemorrhage and a pale yellow liver. Modified from. Chlormequat has been used as an effective height control agent for Calceolaria. Scrophulariaceae and Buddlejaceae contain a considerable number of medicinal plants. R. Arora, ... M.S. Daylength extension was with 0.060 klx of incandescent light. Other plants in this family grown for ornament include Mimulus, Penstemon, Hebe, and Calceolaria. Later, the neurocognitive enhancement in healthy human subjects was confirmed in a double-blind, placebo-controlled trial (Neale et al., 2013). Figwort, (genus Scrophularia), any of about 200 species of coarse herbs of the figwort family (Scrophulariaceae), native to open woodlands in the Northern Hemisphere. Veronica), have four petals, but many have irregular shaped flowers with five petals, often joined to form a bell or tube, sometimes with two lips. Expanded studies by Stermitz and co-workers (68) demonstrated the presence of rhexifoline (23) in specimens of the aerial parts of C. sulphurea, C. occidentalis, and C. rhexifolia, but not C. hispida var. ‘Portia’ responded similarly except it is earlier flowering. Some of them are semi-parasitic (Hay Rattle, Lousewort). Distribution and occurrence: World: 54 genera, c. 1800 species, cosmopolitan.

C. rhexifolia serves as the host for the plume moth, Pletyptilia pica, and the larvae, moth frass, and adults were analyzed for alkaloids.
