Chemical and bioactive comparison of Panax notoginseng root and rhizome in raw and steamed forms
Yin Xiong,Lijuan Chen,Jinhui Man,Yupiao Hu,Xiuming Cui 고려인삼학회 2019 Journal of Ginseng Research Vol.43 No.3
Background: The root and rhizome are historically and officially utilized medicinal parts of Panaxnotoginseng (PN) (Burk.) F. H. Chen, which in raw and steamed forms are used differently in practice. Methods: To investigate the differences in chemical composition and bioactivities of PN root and rhizomebetween raw and steamed forms, high-performance liquid chromatography analyses and pharmacologiceffects evaluated by tests of anticoagulation, antioxidation, hemostasis, antiinflammation, and hematopoiesiswere combined. Results: With the duration of steaming time, the contents of ginsenosides Rg1, Re, Rb1, Rd, and notoginsenosideR1 in PN were decreased, while those of ginsenosides Rh1, 20(S)-Rg3, 20(R)-Rg3, Rh4, and Rk3were increased gradually. Raw PN samples steamed for 6 h at 120 C with stable levels of most constituentswere used for the subsequent study of bioeffects. Raw PN showed better hemostasis, anticoagulation,and antiinflammation effects, while steamed PN exhibited stronger antioxidation andhematopoiesis activities. For different parts of PN, contents of saponins in PN rhizome were generallyhigher than those in the root, which could be related to the stronger bioactivities of rhizome comparedwith the same form of PN root. Conclusion: This study provides basic information about the chemical and bioactive comparison of PNroot and rhizome in both raw and steamed forms, indicating that the change of saponins may have a keyrole in different properties of raw and steamed PN.

Chemical and bioactive comparison of Panax notoginseng root and rhizome in raw and steamed forms
Xiong, Yin,Chen, Lijuan,Man, Jinhui,Hu, Yupiao,Cui, Xiuming The Korean Society of Ginseng 2019 Journal of Ginseng Research Vol.43 No.3

Chen, which in raw and steamed forms are used differently in practice. Methods: To investigate the differences in chemical composition and bioactivities of PN root and rhizome between raw and steamed forms, high-performance liquid chromatography analyses and pharmacologic effects evaluated by tests of anticoagulation, antioxidation, hemostasis, antiinflammation, and hematopoiesis were combined. Results: With the duration of steaming time, the contents of ginsenosides $Rg_1$, Re, $Rb_1$, Rd, and notoginsenoside $R_1$ in PN were decreased, while those of ginsenosides $Rh_1$, $20(S)-Rg_3$, $20(R)-Rg_3$, $Rh_4$, and $Rk_3$ were increased gradually. Raw PN samples steamed for 6 h at $120^{\circ}C$ with stable levels of most constituents were used for the subsequent study of bioeffects. Raw PN showed better hemostasis, anticoagulation, and antiinflammation effects, while steamed PN exhibited stronger antioxidation and hematopoiesis activities. For different parts of PN, contents of saponins in PN rhizome were generally higher than those in the root, which could be related to the stronger bioactivities of rhizome compared with the same form of PN root. Conclusion: This study provides basic information about the chemical and bioactive comparison of PN root and rhizome in both raw and steamed forms, indicating that the change of saponins may have a key role in different properties of raw and steamed PN.
