Enhancement of Macarpine Production in Suspension Cultures under Salicylic Acid Elicitation and Precursor Supplementation.

Macarpine is a minor benzophenanthridine alkaloid with interesting biological activities, which is produced in only a few species of the Papaveraceae family, including . Our present study was focused on the enhancement of macarpine production in suspension cultures using three elicitation models: salicylic acid (SA) (4; 6; 8 mg/L) elicitation, and simultaneous or sequential combinations of SA and L-tyrosine (1 mmol/L). Sanguinarine production was assessed along with macarpine formation in elicited suspension cultures.

Evaluation of Manganese Chloride's Effect on Biosynthetic Properties of In Vitro Cultures of Cham.

The basal production of secondary metabolites in medicinal plants is limited. One of the effective approaches that encourages plants to produce a remarkable amount of precious compounds is an application of elicitors. Our work was focused on the elicitation of Cham.

Agrimonia eupatoria L. and Cynara cardunculus L. Water Infusions: Comparison of Anti-Diabetic Activities.

Diabetes mellitus (DM) is frequently diagnosed at a time when patients already suffer from several cardiovascular complications. Our previously published data (Molecules 201520 (11): 20538-50) on the anti-oxidative properties of Agrimonia eupatoria L. (AE) and Cynara cardunculus L.

[Effect of abiotic elicitation on the sanguinarine production and polyphenol oxidase activity in the suspension culture of Eschscholtzia californica CHAM].

Elicitation of plant in vitro cultures represents a biotechnological tool to improve the production of secondary metabolites. In this study, the effect of AgNO3 and CdCl2 on the sanguinarine production by the suspension culture of Eschscholtzia californica CHAM. was investigated.

[Testing of the potentially probiotic lactobacilli for use in food supplements].

Unlabelled: Some lactobacilli strains are used as probiotics in food industry and in dietary supplements. Eight lactobacilli strains, originated from the stomach of the lamb and goatling, are tested for their potential use in human and/or veterinary medicine in our department. Sanguinarine is a major alkaloid of Papaveraceae suspension cultures.

[Comparison of sanguinarine production in suspension cultures of the Papaveraceae plants].

Intact plants of the Papaveraceae family are producers of a whole range of benzylisoquinoline alkaloids, which are used in pharmaceutical industry. In vitro cultures derived from plants of the Papaveraceae do not have the ability to produce such a broad spectrum of alkaloids, only the biosynthetic pathway leading to sanguinarine is active. This study deals with the preparation of in vitro cultures of Papaver somniferum, Eschscholtzia californica, Chelidonium majus and Macleaya cordata.

[Bacteriocins produced by lactic acid bacteria].

Lactic acid bacteria comprise several genera of gram-positive bacteria that are known for the production of structurally different antimicrobial substances. Among them, bacteriocins are nowadays in the centre of scientific interest. Bacteriocins, proteinaceous antimicrobial substances, are produced ribosomally and have usually a narrow spectrum of bacterial growth inhibition.

Involvement of lipoxygenase in elicitor-stimulated sanguinarine accumulation in Papaver somniferum suspension cultures.
