The transformation of major ginsenosides to minor ginsenosides by microorganisms was considered to be an environmentally friendly method. Compared with GRAS (generally recognized as safe) strains, non-food-grade microorganisms could transform polar ginsenosides to various minor ginsenosides. In this study, screened from the rhizosphere was capable of transforming PPD-type and PPT-type ginsenosides in the underground parts of to 18 minor ginsenosides. The transformation reactions invovled deglycosylation, epimerization, and dehydration. To the best of our knowledge, this transformation characteristic of was first reported in fungi. Its crude enzyme can efficiently hydrolyze the outer glucose linked to C-20 and C-3 in major ginsenosides Rb, Rb, Rb, Rc, Rd, and 20()-Rg within 48 h. The transformation of major ginsenosides to minor ginsenosides by will help raise the functional and economic value of .

is a traditional Chinese medicinal plant of considerable application value and commercial potential, primarily due to its production of various bioactive compounds, particularly dammarane-type triterpenoid saponins that are structurally analogous to ginsenosides. Oxidosqualene cyclase (OSC), a pivotal enzyme in the biosynthesis of triterpenoid metabolites in plants, catalyzes the conversion of oxidosqualene into triterpenoid precursors, which are essential components of the secondary metabolites found in . To elucidate the role of gene family members in the synthesis of gypenosides within , this study undertook a comprehensive genome-wide identification and characterization of genes within and compared their expression levels across populations distributed over different geographical regions by both transcriptome sequencing and qRT-PCR experimental validation.

The effects of puffing on the ginsenoside composition as well as antioxidant and anti-inflammatory activities of ginseng berry were investigated to increase the utilization of ginseng berry. There was no significant difference in extraction yield between the control and puffed samples at all moisture contents and pressure conditions ( < 0.05).

β-Glucosidase plays a pivotal role in transforming ginsenosides into specific minor ginsenosides. In this study, total ginsenosides from Panax notoginseng leaves were used as substrates to stimulate the growth of Aspergillus niger NG1306. Transcriptome analysis identified a β-glucosidase gene, Anglu04478 (1455 bp, 484 amino acids, 54.

Minor ginsenosides have demonstrated notable anti-fatigue capabilities. The aim of this study was to investigate the anti-fatigue mechanisms of total minor ginsenosides (TMGs) derived from a process involving probiotic fermentation and high-pressure steam treatment. The fatigue model was established in BALB/c male mice using weight-bearing swimming and TMGs were administered by orally at a dosage of 200 mg/kg for four weeks.
