“…The changes in the calli pigments and its intensity were visualized in the first week after exposing the plates in an environment treated by different kinds of light (visual observations, data not shown), firstly in white light. Reports have demonstrated that betalains biosynthesis occurs between the sixth and fifteenth days, but is most intense towards the ninth day (Radfar et al, 2012).…”

“…The MS medium containing IAA (0.75 mg L -1 ) and 2,4-D (1 mg L -1 ) exposed to blue and white lights have been highlighted as the strongest inductors for production and intensification of the pigments. In studies that used Zaleya decandra calli grown under white light (Radfar et al, 2012), the highest pigments intensity was seen when the samples were cultured on the MS-plus-TDZ (2 mg L ). However, it is not entirely clear whether the intense pigmentation is due to an increase of metabolic activity in individual cells, or simply an increase in the number of cells able to produce betalains (Kishima et al, 1991).…”

Alternanthera brasiliana is a medicinal plant with several popular use and high production of betalains. The aim of the present research was to establish a protocol for callus induction and betalain biosynthesis in A. brasiliana species, as well as to investigate the effect of different qualities of light in increasing betalain in A. brasiliana callus cultures. In this way, the callus initiation and the improvement of secondary metabolites were induced using varying phytohormones concentrations and under the influence of red, white and blue lights. To start the experiments, the plants were cultivated for 30 days in Murashige and Skoog (MS) medium to grow and form internodes. These were inoculated in MS medium supplemented with different combinations of plant growth regulators to find the best combination for medium callus induction (MCI). After another 30 days, the explants were transferred to a medium for betacyanin induction (MBI) containing thidiazuron (TDZ) and α-naphthalene acetic acid (NAA) under blue, white, and red lights. The best medium for A. brasiliana callus induction with higher production of betalains, was the MS medium supplemented white indole-3-acetic acid (IAA) and 2,4dichlorophenoxyacetic acid (2,4-D), before inoculation on the MBI. The blue and white lights promoted callus pigmentation (betalains), whereas the red light was not effective at inducing pigmentation in the calli.

“…In the present study the increase of phenols it can be due to the excess production of H2O2 in elicited plant cells through increased respiration (Farkas and Kiraly, 1962) or due to the activation of hexosemonophosphate pathway, acetate pathway and release of bound phenols by hydrolytic enzymes. Moreover, callus cultures can be employed and exploited for secondary metabolites production (Jedinák et al, 2004;Radfar et al, 2012). In tissue culture procedures, this used frequently for production of flavonoids.…”

Effects of sodium nitroprusside (SNP; nitric oxide donor) treatment on the enhancement of secondary metabolites production, oxidative stress mediators (O 2 -. ) accumulation and antioxidant defense enzymes of Ginkgo biloba callus culture was investigated. On one hand, the obtained data showed a highly metabolic modification of chemical constituents, PAL activity and various antioxidant defense enzymes (APX, SOD), which gradually increased in response to SNP treatments. On the other hands the high NO levels significantly increased the accumulation of various oxidative burst of O 2 -.. MS basal medium supplemented with casein hydrolase (500 mg/L), NAA and BA at equal concentration (0.5 mg/L) recorded the highest number of regenerated shoots (4.81 cm) and shoot height (4.96 cm) as well as root number (2.25 cm) and root length (4.5 cm). The highest survival (40 %) was shown in acclimatization on the mixture containing sand, peat moss and vermiculite (1: 1: 1, v/v/v), which significantly confirmed and reflected the variation in survival percentage. Meanwhile, higher treatment (500 µM) of NO positively enhanced secondary products accumulation of total tannins, saponins, phenols and total flavonoids in G. biloba callus culture.

The purpose of this study was to evaluate anti-trichophytic effects of Baillonella toxisperma (Pierre) extracts against Trichophyton rubrum and Trichophyton soudanense. The tests were performed by the agar dilution method and the results have showed the effective inhibition of the mycelia growth of theses strains by B. toxisperma (Pierre) extracts. After 7 days of incubation at 28°C, the percentages of mycelia growth inhibition PI (%) by plant extracts and fluconazole were range between 20.81 and 100% on T. soudanense, and between 19.92 and 100% on T. rubrum. Some B. toxisperma (Pierre) extracts were exhibited similar anti-trichophyton activities compared to those obtained with fluconazole which was used like reference antifungal drug (p < 0.05). The best anti-trichophyton activities of B. toxisperma (Pierre) extracts were obtained at 5 mg/ml on T. Rubrum with almond oil and hexane phase of water-hexane partition of hydro-ethanol crude extract of barks bromobentseeni (HBb), and at 10 mg/ml on T. soudanense with (HBb). This anti-trichophyton activity of B. toxisperma (Pierre) extracts was attributed to secondary metabolites. The phytochemical analysis has showed that the plant contain bioactive metabolites groups such as phenols, flavonoids, saponins, coumarin, tanins, anthocyanins, lipids and triterpenes. The metabolic groups have been mentioned in several studies for their antifungal activities. The results from this study provide a scientific validation for the ethnomedicinal uses of B. toxisperma (Pierre) in the treatment of fungal infections.
