Background: Ginseng, officially known as Panax ginseng Meyer, has been traditionally used as a medicinal herb, particularly in Asia. Ginseng is propagated from seeds; however, seed germination is challenging, especially in its natural environment on farms. The seeds typically exhibit morphophysiological dormancy and require release from both morphological and physiological dormancy before germination. Although some studies have proposed methods for increasing seed germination rates, the underlying mechanisms of its dormancy release process remain unclear. Here, we investigated metabolic alterations during dehiscence in P. ginseng to determine their potential roles in dormancy release. Methods: We compared the ginseng seed metabolome before and after dehiscence and the ginsenoside and phytosterol compositions of the seeds in both periods in the presence of related enzymes. Results: After seed dehiscence, the sugar, amino acid, and squalene concentrations were significantly altered, phytosterols associated with the stigmasterol biosynthesis pathway were increased, while ginsenoside and brassinosteroid levels were not significantly altered. In addition, squalene epoxidase, cycloartenol synthase, 24-methylenesterol C-methyltransferase, and the stigmasterol biosynthesis pathway were activated. Conclusion: Overall, our findings suggest that morphological activities that facilitate ginseng seed growth are the primary phenomena occurring during the dehiscence process. This study improves the understanding of P. ginseng germination processes and promotes further research of its germination and cultivation.

Background: Various treatments are used to relieve menopausal symptoms for women. However, herbal substances are frequently used as complementary and alternative therapies as other treatments can increase ovarian and breast cancer risk. While the herbal substances' therapeutic effect is essential, the safety of their use is considered more important. This study aims to confirm the safety of red ginseng and herb extract complex (RHC), which are used to relieve menopausal symptoms. Methods: This randomized, double-blind, placebo-controlled clinical study recruited and divided 120 women experiencing menopausal symptoms into the RHC and placebo groups (60 women per group). Subjects were administered with 2 g RHC or placebo daily for 12 wk. Adverse reactions, female hormonal changes, and uterine thickness were observed and recorded on wk 0, 6, and 12. Hematologic and blood chemistry tests were also conducted. Results: The reactions of the subjects who received RHC or placebo at least once were analyzed. A total of six adverse reactions occurred in the RHC group, while nine occurred in the placebo group; common reactions observed in both groups were genital, subcutaneous tissue, and vascular disorders. However, there was no statistically significant difference between the administration groups (p = 0.5695), and no severe adverse reactions occurred in both groups.

Background: Gray mold, caused by Botrytis cinerea, is one of the major fungal diseases in agriculture. Biological methods are preferred over chemical fungicides to control gray mold since they are less toxic to the environment and could induce the resistance to pathogens in plants. In this work, we try to understand if ginseng defense to B. cinerea could be induced by fungal hypovirulent strain △BcSpd1. BcSpd1 encodes Zn(II)₂Cys₆ transcription factor which regulates fungal pathogenicity and we recently reported △BcSpd1 mutants reduced fungal virulence. Methods: We performed transcriptomic analysis of the host to investigate the induced defense response of ginseng treated by B. cinerea △BcSpd1. The metabolites in ginseng flavonoids pathway were determined by UPLC-ESI-MS/MS and the antifungal activates were then performed. Results: We found that △BcSpd1 enhanced the ginseng defense response when applied to healthy ginseng leaves and further changed the metabolism of flavonoids. Compared with untreated plants, the application of △BcSpd1 on ginseng leaves significantly increased the accumulation of p-coumaric acid and myricetin, which could inhibit the fungal growth. Conclusion: B. cinerea △BcSpd1 could effectively induce the medicinal plant defense and is referred to as the biological control agent in ginseng disease management.

Korean Ginseng is a medicinal herb which grows naturally in korea. an ancient country situated in north-eastern Asia. Its medical use was already well known to herb doctors in this region about five thousand years ago since the effectiveness of korean ginseng has been recognized through practical use for a long time. Korean Ginseng has always been regarded as a devine cure. The name "Ginseng" can be found in various medicinal books. many of which were written as early as B.C. 100. In the records of many chinese medical books. dating from the inception of publishing, it was noted that Korean Ginseng was of the highest level of quality. Korean Ginseng originally grew in the mountains of korea. However, this wild Korean Ginseng(js called SANSAM) could not meet the ever-increasing demands. and from the 16th century. it has been cultivated on farms for mass processing and supplying in korea(js called INSAM). It was already recognized in korea a long time ago(B.C. 57 - A.D. 668) that Korean Ginseng possessed the qualities of panacea, tonic and rejuvenator, and had other medicinal properties as well. The effectiveness of Korean Ginseng is widely recognized among south-eastern Asians as well as Chinese. As its effect has been proved scientifically. Korean Ginseng is now becoming the ginseng for all human beings in the world. Korean ginseng is differently called according to processing method. Dried thing is Insam(white ginseng), boiled or steamed is Hongsam(red ginseng). 장뇌삼(long headed ginseng) is artificially grown in the mountain no in field for a long time. So the body is thin and some long. but ingredients are concentrated. Korean wild ginseng(SANSAM) is rare in these days but we developed cosmetic ingredient. The scientific name of Korean Ginseng is Panax Ginseng. It has acknowledge as a natural mysterious cure among the notheastern peoples. because of its broad medicinal application. The origin of the word" Panax" derived from panacea. a Greek word meaning cure-all. According to the classification method of herb medicines in the Chinese medicinal book. "God-Farmer Materia Medica(A.D. 483-496) korean Ginseng was described as the superlative drug: panacea. tonic and rejuvenator. We studied skin immunological effect. collagen synthesis. cell growth and whitening effect of SANSAM extract. IN cosmetics.. SANSAM extract had skin fibroblast cell growth effect. recover damaged skin in the sun and protect fine wrinkle. Also. In hair product.. inhibits hairless, white hair.its hairless, white hair.

The potential factors for quality loss of cleaned fresh ginseng and technology to be associated with the improvement of marketability through pre-packaging fumigation were examined. Major microorganisms isolated from fresh ginseng included Botrytis cinerea, and Erwinia sp. Others such as Cylindrocarpon sp., Fusarium spp., Pennicilium spp., Bacillus spp. were also found at relatively low frequency. The bacterial density of vacuum packaged fresh ginseng rapidly increased during simulated marketing. Little correlation between bacterial growth and package swelling was found. In order to improve packaging method of fresh ginseng, pre-packaging treatment of 2-phenylethyl alcohol (PE, 100 uL/L, 4 hr) was examined. The fumigation treatment effectively inhibited the growth of bacteria density and also effective on keeping firmness of ginseng root, especially in cortical portion. The internal gas compositions of plastic container packaged for ginseng were approximately ranged between 6 to 8% $O_2$and 3 to 4% $CO_2$. The $O_2$ level of fumigation treatment was lower than control whereas $CO_2$ level was higher. The upsurge of ethylene evolution I day after simulated marketing was found only in fumigation treatment but it returned to ordinary level at day 2. The sucrose content of 2-PE treatment was significantly reduced at 5 days after simulated marketing but reducing sugars like glucose and fructose remained at higher level. The difference in sugar levels was reduced after 10 days of simulated marketing. The decay of fresh ginseng began at the lateral or fine root, which is weak to physical damage, in general. The epidermis was more damaged. Plastic container packaging with PE fumigation could be an alternative to vacuum packaging, which allows an aerobic environment and prevents anaerobic respiration. Further study of pre-package fumigation is required to improve technology of fresh ginseng marketing.

Schizonepeta spike (Korean name "Hyung-Gae") has been used for oriental medicinal purposes in Korea, China and Japan. In this study, twenty six "Hyung-Gae" samples were collected including nine certified Schizonepeta tenuifolia plants, and seventeen commercially marketed "Hyung-Gae" products. Chloroplast trnL-F and rDNA ITS regions of the "Hyung-Gae" samples were sequenced and used to identify whether the samples were genuine S. tenuifolia or not. As the result, the trnL-F and ITS sequences of all the "Hyung-Gae" samples were shown to be identical and it was proven that commercially available medicinal products "Hyung-Gae" are genuine S. tenuifolia. Phylogenetic tree of S. tenuifolia using the trnL-F sequences was constructed and compared with phylogenetic tree using ITS of rDNA region sequences. In these tree, S. tenuifolia was affiliated in the family Lamiaceae. It is proven that trnL-F and ITS phylogenetic trees are useful to study taxonomic position of S. tenuifolia.

Background: Among the various ginseng strains, Shizhu ginseng is endemic to China, mainly distributed in Kuandian Manchu Autonomous County (Liaoning Province, China); however, not much is known about the compounds (especially saponins) in Shizhu ginseng. Methods: A rapid, sensitive, and reliable ultra-high performance liquid chromatography coupled with MS/MS (UHPLC-MS/MS) method was developed to separate and identify saponins in Shizhu ginseng. Results: The separation was carried out on a Waters ACQUITY UPLC BEH $C_{18}$ column ($100mm{\times}2.1mm$, $1.7{\mu}m$) with acetonitrile and 0.1% formic acid aqueous solution as the mobile phase under a gradient elution at $40^{\circ}C$. The detection was performed on a Micromass Quattro Micro API mass spectrometer equipped with electrospray ionization source in both positive and negative modes. Under the optimized conditions, a total of 31 saponins were identified or tentatively characterized by comparing retention time and MS data with related literatures and reference substances. Conclusion: The developed UHPLC-MS/MS method was suitable for identifying and characterizing the chemical constituents in Shizhu ginseng, which provided a helpful chemical basis for further research on Shizhu ginseng.

The purpose of this study was to evaluate the quality properties of muffin added with different concentration (0, 1, 3, and 5%) of ginseng leaves powder, which is discarded in the process of ginseng. Density of muffin was the highest at 1.45 g/mL in control, and pH (7.41) was at the highest level as well. There was no tendency at the bottom and upper dimensions according to addition of ginseng leaf powder. The height and baking loss rate of the muffins increased with increase in the powder concentration, but there were no significant differences. The weight of muffins did not show constant tendency, according to addition ratio of ginseng leaves powder. The degree of lightness and yellowness of muffin decreased as the concentration of the powder increased, whereas no significant difference in the redness was found with increased powder concentration. The factors of hardness and chewiness were higher at the control group and cohesiveness was the highest at 0.65 in 3% group, but springiness and gumminess did notshow significant differences. DPPH free radical scavenging activity of muffins was significantly increased with increasing ginseng leaves powder (p<0.05). For the sensory evaluation in 1% group, the intensity of color, smell, taste, softness, and moistness was the lowest, whereas the overall acceptability score of color, smell, taste, chewiness, and moistness was the highest. Thesensory properties of muffin linearly decreased as the concentration of ginseng leaves powder increased. Taken together, the results of this study suggest that ginseng leaf powder is a good ingredient for increasing the consumer acceptability and functionality of cookies.
