Three minor ginsenosides, namely, ginsenoside Rh6 (1), vina-ginsenoside R4 (2) and vina-ginsenoside R13 (3), were isolated from the leaves of hydroponic Panax ginseng. The chemical structures were determined based on spectroscopic methods, including fast atom bombardment mass spectroscopy (FAB-MS), 1D-nuclear magnetic resonance (NMR), 2D-NMR, and, infrared (IR) spectroscopy. The melanogenic inhibitory activity of compounds 1, 2 and 3 was 23.9%, 27.8% and 35.2%, respectively, at a concentration of 80 µM. Likewise, the three compounds showed inhibitory activity on body pigmentation on a zebrafish model, which is commonly used as a model for biomedical or cosmetic research. These results from in vitro and in vivo systems suggest that the three aforementioned compounds isolated from Panax ginseng may have potential as new skin whitening compounds.

Cholinergic deficiency and neuroinflammation are the two main factors of Alzheimer's disease. Recent studies have shown that water-soluble ginseng oligosaccharides (WGOS) derived from Panax ginseng roots can protect against scopolamine-induced impairments in learning and memory. However, the fundamental mechanisms remain unclear for the most part.

Introduction: Functional rhizosphere microbiomes (FRM) are critical for plant health and yield. However, the ecological succession of FRM and their links to plant genetic factors across the life cycle of perennial plants remain poorly understood.
Methods: This study profiled FRM, including plant-beneficial bacteria (PBB) and fungal plant pathogens (FPP), across different developmental stages of .

There are abundant glycosylated substances such as cellulose, hemicellulose, and phytochemical glycosides in plants, which could be converted into functional chemicals such as monosaccharides, oligosaccharides, and bioactive aglycones by cleavage of glycosidic bonds using glycoside hydrolases (GHs). Among those GHs, β-glucosidase and β-xylosidase are the rate-limiting enzymes for degrading cellulose and hemicellulose, respectively, and can convert a variety of glycosylated substances. These two enzymes play important roles in the high value use of plant resources and have great potential applications.

Hepatitis is a chronic inflammatory liver disease and an important cause of liver fibrosis, which can progress to cirrhosis and even hepatocellular carcinoma if left untreated. However, liver fibrosis is a reversible disease, so finding new intervention targets and molecular markers is the key to preventing and treating liver fibrosis. Ginseng, the roots of Panax ginseng C.

Introduction: The biological activities of osthole have been widely reported in recent years. However, few studies have been conducted on osthole in agriculture, and its effects on plant growth have little been reported.
Methods: Three experimental treatments were set up in this experiment: blank control (CK), osthole (CLS), and (LKWS).
