Ginseng is widely used for its promising healing and restorative properties as well as for its possible tonic effect in traditional medicine. Nowadays, many studies focus on purified individual ginsenoside, an important constituent in ginseng, and study its specific mechanism of action instead of whole-plant extracts on cardiovascular diseases (CVDs). Of the various ginsenosides, purified ginsenosides such as Rb1, Rg1, Rg3, Rh1, Re, and Rd are the most frequently studied. Although there are many reports on the molecular mechanisms and medical applications of ginsenosides in the treatment of CVDs, many concerns exist in their application. This review discusses current works on the countless pharmacological functions and the potential benefits of ginseng in the area of CVDs. Results: Both in vitro and in vivo results indicate that ginseng has potentially positive effects on heart disease through its various properties including antioxidation, reduced platelet adhesion, vasomotor regulation, improving lipid profiles, and influencing various ion channels. To date, approximately 40 ginsenosides have been identified, and each has a different mechanism of action owing to the differences in chemical structure. This review aims to present comprehensive information on the traditional uses, phytochemistry, and pharmacology of ginseng, especially in the control of hypertension and cardiovascular function. In addition, the review also provides an insight into the opportunities for future research and development on the biological activities of ginseng.

Object To find out which of the 27 ginsenosides isolated from Panax ginseng C.A. Mey that may inhibit the proliferation of human osteosaocoma cell line $U_2OS$. Methods Effects of each individual ginsenoside on the proliferation of $U_2OS$ cell were studied by determining the viability of cancer cells during culture with or without the presence of the test compound. DNA assay was determined by flow cytometry. Results Ginsonosides -Ro, $-Rh_l,\;-Rh_2,\;-F_1\;and\;-L_8$ at concentrations of 5 ,umol/L could obviously suppress the proliferation of $U_2OS$ cells while ginsenosides $-Rg_1,\;-F_3,$ -Rf, PPT and PT significantly inhibited the cancer cells. Flow cytometry revealed that ginsenosides $-Ro,-Rg_1-Rf,-F_1-Rh_2,PPT$ and PT induced cell cycle arrest at $G_0/G_1$ phase with obvious decrease of cell count at Sand $G_2+M$ phase, Moreover, ginsenosides $-Rf_1,-Rg_1,\;-F_1$ and PPT induced significantly high rates of cell death as compared with the control. Conclusion These data suggested that ginsenosides inhibited $U_2OS$ proliferation Via cell cycle arrest or induction of cell death.

A high performance liquid chromatography (HPLC) method has been successfully developed to identify and quantify major ginsenosides in Korean ginseng seeds and roots. Using gradient elution of acetonitrile and water without buffer, the 6 major ginsenosides ($Rb_1,\;Rb_2$, Rc, Rd, Re, and $Rg_1$) were identified. Compared with ginseng roots, the amount of ginsenoside Re and Rd in ginseng seeds were significantly higher than those in ginseng roots (p<0.05). In ginseng seeds, the content of protopanaxtriol (PPT) was higher than that of protopanaxdiol (PPD) and the ratio of PPT and PPD was approximately 2.2 : 1. However, the content of PPT was lower than that of PPD in ginseng roots. It should be mentioned that both content of PPT and PPD in ginseng seeds were much higher than those in ginseng roots.

Background: Ginsenosides (GS) have potential value as cosmetic additives for prevention of skin photoaging. However, their protective mechanisms against skin barrier damage and their active monomeric constituents are unknown. Methods: GS monomer types and their relative proportions were identified. A UVB-irradiated BALB/c hairless mouse model was used to assess protective effects of GS components on skin epidermal thickness and transepidermal water loss (TEWL). Skin barrier function, reflected by filaggrin (FLG), involucrin (IVL), claudin-1 (Cldn-1), and aquaporin 3 (AQP3) levels and MAPK phosphorylation patterns, were analyzed in UVB-irradiated hairless mice or HaCaT cells. Results: Total GS monomeric content detected by UPLC was 85.45% and was largely attributed to 17 main monomers that included Re (16.73%), Rd (13.36%), and Rg1 (13.38%). In hairless mice, GS ameliorated UVB-induced epidermal barrier dysfunction manifesting as increased epidermal thickness, increased TEWL, and decreased stratum corneum water content without weight change. Furthermore, GS treatment of UVB-irradiated mice restored protein expression levels and epidermal tissue distributions of FLG, IVL, Cldn-1, and AQP3, with consistent mRNA and protein expression results obtained in UVB-irradiated HaCaT cells (except for unchanging Cldn-1 expression). Mechanistically, GS inhibited JNK, p38, and ERK phosphorylation in UVB-irradiated HaCaT cells, with a mixture of Rg2, Rg3, Rk3, F2, Rd, and Rb3 providing the same protective MAPK pathway inhibition-associated upregulation of IVL and AQP3 expression as provided by intact GS treatment. Conclusion: GS protection against UVB-irradiated skin barrier damage depends on activities of six ginsenoside monomeric constituents that inhibit the MAPK signaling pathway.

This study was carried out to investigate the changes of ginsenosides composition in Korean red ginseng water extract (RGWE) after heated with high temperatures above $100^{\circ}C$. RGWEs were adjusted with pH 3.0, pH 7.0 and pH 10.0, respectively, and then heated at 100,110 and $120^{\circ}C$ for 30 minutes by using autoclave. Total ginsenosides of RGWE treated with heating showed decreasing tendency when compared with control. By TLC analysis, decreasing effect of ginsenosides in RGWE were significantly observed in the acidic condition of pH 3.0, particulary. By HPLC analysis, total ginsenoside of control showed 1.89%, while those of RGWE treated with 100, 110 and $120^{\circ}C$ showed 1.22, 1.05 and 0.97%, respectively. The ratio of protopanaxadiol (PD) to protopanaxatriol (Pr) saponins in control was 1.89, while that of PD/PT in treated RGWEs were level of 1.33 to 1.47. By the result of decreased ratio of PD/PT in RGWE, it was considered that PD type saponin such as ginsenoside$-Rb_{1}$, $-Rb_{1}$, -Rc and -Rd was more unstable than PT type saponin such as ginsenoside-Re and Rg against high temperature heating above $100^{\circ}C$.

Rice wine (makgeolli) containing various amounts of mountain ginsengs (MG) are being prepared with nuruk and yeasts, and the physicochemical characteristics and contents of ginsenosides in MG-makgeolli were analyzed. Average particle size of MG powder is $29.1{\mu}m$. MG slice (20 g) or powder (0~20 g) and rice (3,000 g) were used for 12 days fermentation of makgeolli, makgeolli containing slice of MG (SW-makgeolli), makgeolli containing 2 g (PW1-makgeolli), 10 g (PW2- makgeolli), 20 g (PW3-makgeolli) of powder of MG, respectively. Soluble solids and pH levels show no differences between five kinds of makgeolli groups, whilst the presence of high amounts of MG (PW3-makgeolli) caused decreases in ethanol and acidity. Major free amino acids in MG-makgeolli are glutamic acid and arginine. Total contents of 14 ginsenosides are approximately 2.5 g/100 g of dried MG powder and major ginsenoside were ginsenosides Re, Rb1, Rb2, Rg1, Rc and Rf. During the propagation of makgeolli containing MG, the ginsenosides Rb1, Rb2, Rb3, and Rc decreased, whilst ginsenosides Rg3 and compound K increased highly. It indicates that ginsenosides in MG are metabolized to different forms of ginsenosides by brewing microorganisms.
