The Effect of a Combination of and on Alleviation of Testosterone Deficiency in Aged Rat Models.

With aging, men inevitably encounter irreversible changes, including progressive loss of testosterone and physical strength, and increased fat mass. To assess the alleviatory effects of EUAJ on andropause symptoms, including in vivo testosterone deficiency, we administered EUAJ for 6 weeks in 22-week-old Sprague-Dawley rats. Before EUAJ (3:1) (: = 3:1, KGC08EA) administration, testosterone decline in 22-week-old SD rats was confirmed compared to 7-week-old SD rats (NC group).

Effects of red ginseng oil(KGC11) on testosterone-propionate-induced benign prostatic hyperplasia.

Background: Benign prostatic hyperplasia (BPH) is a disease characterized by abnormal proliferation of the prostate, which occurs frequently in middle-aged men. In this study, we report the effect of red ginseng oil (KGC11) on BPH.

Methods: The BPH-induced Sprague-Dawley rats were divided into seven groups: control, BPH, KGC11 25, 50, 100, 200, and finasteride groups.

Therapeutic effects of non-saponin fraction with rich polysaccharide from Korean red ginseng on aging and Alzheimer's disease.

Biological aging provokes morbidity and several functional declines, causing older adults more susceptible to a variety of diseases than younger adults. In particular, aging is a major risk factor contributing to non-communicable diseases, such as neurodegenerative disorders. Alzheimer's disease (AD) is an aging-related neurodegenerative disease that is characterized by cognitive deficits and the formation of amyloid plaques formed by the accumulation of amyloid-β (Aβ) peptides.

analysis of chemical components induced by steaming between fresh ginseng, steamed ginseng, and red ginseng.

Background: The chemical constituents of are changed by processing methods such as steaming or sun drying. In the present study, the chemical change of induced by steaming was monitored .

Methods: Samples were separated from the same ginseng root by incision during the steaming process, for monitoring.

Characterization of Korean Red Ginseng (Panax ginseng Meyer): History, preparation method, and chemical composition.

It has been reported that Korean Red Ginseng has been manufactured for 1,123 y as described in the GoRyeoDoGyeong record. The Korean Red Ginseng manufactured by the traditional preparation method has its own chemical component characteristics. The ginsenoside content of the red ginseng is shown as Rg1: 3.

New Method for Simultaneous Quantification of 12 Ginsenosides in Red Ginseng Powder and Extract: In-house Method Validation.

For quality control of components in Korean red ginseng powder and extract, a new method for simultaneous quantification of 12 ginsenosides (Rg1, Re, Rf, Rh1, Rg2[S], Rg2[R], Rb1, Rc, Rb2, Rd, Rg3[S], and Rg3[R]) was studied. Compared to the official method for quantification of marker substances (ginsenosides Rg1 and Rb1), the proposed methods were guaranteed by in-house method validation. Several criteria such as linearity, specificity, precision and accuracy were evaluated.
