One of the challenges of the pharmaceutical and cosmetic industries is to deliver biochemical compounds that can be advantageous for the skin. Research on Boraginaceae taxa has confirmed their use in traditional medicine and proved the potential biological importance of various molecules in cosmetology. The main classes of valuable compounds associated with Boraginaceae taxa are fatty acids, including γ-linolenic acid, essential oils, phenolic acids (e.

A precursor feeding strategy was used for the first time in agitated microshoot cultures of . This strategy involved the addition of biogenetic precursors of simple phenolic acids (phenylalanine, cinnamic acid, and benzoic acid) and depsides (caffeic acid) into the culture media, with an assessment of its effect on the production of these bioactive compounds. The in vitro cultures were maintained in Murashige-Skoog medium (1 mg/L BAP and 1 mg/L NAA).

The purpose of this study was to evaluate the phytochemical profiles of the seeds, sprouts, leaves, flowers, roots and herb of and to demonstrate their significant contribution to antioxidant and antimicrobial activities. Applied methods were: HPLC-DAD coupled with post-column derivatization with ABTS reagent, untargeted metabolomics performed by LC-Q-Orbitrap HRMS, and two-fold micro-dilution broth method, which involved suspending a solution of tested compounds dissolved in DMSO in Mueller-Hinton broth for bacteria or Mueller-Hinton broth with 2% glucose for fungi. Metabolomic profiling using LC-Q-Orbitrap HRMS used in this study yielded the identification and preliminary characterization of one hundred fifteen compounds.

The use of plant secondary metabolites has gained considerable attention among clinicians in the prevention and treatment of cancer. A secondary metabolite isolated mainly from the roots and rhizomes of Podophyllum species (Berberidaceae) is aryltetralin lignan - podophyllotoxin (PTOX). The purpose of this review is to discuss the therapeutic properties of PTOX as an important anticancer compound of natural origin.

The effect-directed detection (EDD) of fruit and leaves extracts was performed to assess their pharmacological properties. The EDD comprised TLC-direct bioautography against , a DPPH assay, as well as α-glucosidase, lipase, tyrosinase, and acetylcholinesterase (AChE) inhibition assays. The leaf extracts showed stronger antioxidant activity than the fruit extract as well as inhibition of tyrosinase and lipase.

The in vitro cultures of the following three species of the genus were investigated: , , and . The dynamics of biomass growth and accumulation of secondary metabolites in the 3-, 4-, 5-, 6-, and 7-week growth cycle were analysed. The antioxidant capacity of the methanol extracts obtained from the biomass of the in vitro cultures was also assessed by different in vitro assays: 1,1-diphenyl-2-picrylhydrazil (DPPH), reducing power, and Fe chelating activity assays.
