The Atomic Absorption Spectrophotometry method for quantifying the lead and copper content of some herb products containing Panax pseudoginseng was reported. The proposed process of analyzing, using Graphite Furnace Atomizing Mode, were applied for 5 randomly selected samples and proved to be accurate. Results: Lead calibration curve: standard solution have exact lead concentrations of 10, 20 and 30ng/ml in 2% nitric acid. Copper calibration curve: standard solutions have exact copper concentration of 5, 10 and 20ng/ml in 2% nitric acid. Both techniques for decomposition of samples, wet ashing and microwave can be used in preparation of sample solutions

50 compounds isolated from "Ngoc Linh" ginseng in which 26 compounds had known chemical structure and 24 compounds were new chemical structure " Ngoc Linh " contains mainly saponine triterpenoid but content of sapopine pammaran in "Ngoc Linh" ginseng was highest centent (12-15%) and number of saponin in "Ngoc Linh" ginseng was biggest compared with other species of panax in the world.

OBJECTIVE: To investigate the current status and further development of Panax genus and 6 important individual species including P. notoginseng, P. quinquefolium, P. vietnamensis, P. japonicus, P. stipuleanatus and P. zingiberensis. METHODS: The bibliometric analysis was based on the Web of Science core database platform from Thomson Reuters. Totally, 7,574 records of scientific research of Panax species published from 1900-2019 were analyzed. The statistical and visualization analysis was performed by CiteSpace and HistCite software. RESULTS: The academic research of Panax species increase promptly. Plant science is the main research field while research and experimental medicine and agricultural engineering will be the further development tendency. Particularly, the discrimination research of P. notoginseng will be the research tendency among Panax species, especially diversity research. In addition, P. vietnamensis deserves more attention in the genus Panax. CONCLUSION This research provides a reference for further research of the genus and individual species.

OBJECTIVE: A meta-analysis was performed to determine effect of ginseng on blood pressure. METHODS: The databases of PubMed, Embase, Cochrane Library, RISS, DBpia, KISS, and Koreamed were searched for all published studies from inception to January 2016. The following terms were used: "ginseng", "hypertension", and "blood pressure". Using the Review Manager 5, mean differences (MDs) were pooled to measure the effect of ginseng on blood pressure compared to that of placebo. RESULTS: Eleven randomized controlled trials were included. In this meta-analysis, ginseng treatment significantly lowered systolic blood pressure (SBP) in a dose-independent way (MD: -1.99, p = 0.04). In subgroup analysis, 8-12 week consumption of ginseng achieved significantly greater reduction in SBP (MD: -3.14, p = 0.03), while single administration of ginseng failed to show BP-lowering effect. When ingested over 8-12 weeks, ginseng significantly lowered diastolic blood pressure (DBP) (MD: -1.96, p = 0.03). No significant association was found between ginseng dose and the magnitude of BP-lowering effect. However, a significant positive relationship was observed between baseline SBP level and the magnitude of SBP reduction (r = 0.848, p = 0.033). Such a relationship was not seen in DBP. CONCLUSION: Consumption of ginseng for 8-12 weeks achieved significant reductions in SBP and DBP in a dose-independent way. There was a significant positive relationship between baseline SBP level and the magnitude of SBP reduction.

The fluidextract of PG (2ml contains 1 g radix of PG) was used to evaluate its cardio vascular effects on dog blood pressure, frog isolated intestine. Our experimental results show that: The fluidextract of PG in dose of 0.7g/kg body of weigh (correspond to the clinical dose) per oral route decreases blood pressure by 24.1% in comparison with initial level. PG influences both on the heart frequency and on the heart amplitude depending on the utilizing doses. Low doses have stimulating effect whereas high doses inhibiting one. PG with our experimental doses provoke vasodilatation but don't influence on the intestinal peristalsis

The Panax vietnamensis (K5 panax, Ngoc Linh panax) known as its scientific name is Panax vietnamensis Ha et Grushv., belonging to Araliaceae. K5 panax is the 3rd genus of panax L. branch and the 20th in the world. The mojoir components of Panax vietnamensis are determined the majonosid R2, 17 fat acide with 0.53% contents.
