AMENDMENTS OF GEOGRAPHICAL INDICATION REGISTRATION CERTIFICATE OF “NGỌC LINH” FOR GINSENG

“Ngọc Linh” has been registered as geographical indication (GI) for ginseng by GI Registration Certificate No. 00049

“Ngọc Linh”  has been registered as geographical indication (GI) for ginseng by  GI Registration Certificate No. 00049 attached to Decision No. 3235/QD-SHTT dated 18 June 2016 of the Director General of National Office of Intellectual Property (NOIP). As stipulated in this Decision, ginseng products bearing the GI are from Ngọc Linh mountain within territories of Măng Ri and Ngọc Lây communes f (Tu Mơ Rông district, Kon Tum province) and Trà Linh commune  (Nam Trà My district, Quảng Nam province).

Ngọc Linh Ginseng is a herbaceous plant with scientific name of Panax vietnamensis and belongs to  Araliaceae family. Before the discovery of scientists, Ngọc Linh ginsengs had been used by  ethnic minorities as a traditional medicine from wild plant that can cure many ailments. Ngọc Linh Ginseng has officially been known in Viet Nam since 19 March 1973. During the last 40 years, domestic and international scientists have proven that Ngọc Linh Ginseng is the  rare and best gingseng in the world. For such special quality of Ngọc Linh Ginseng, on 16 August 2016, the National Office of Intellectual Property (NOIP)  issued Decision No. 3235/QD-SHTT on granting Certificate of Geographical Indication Registration No. 00049 for Ngọc Linh Ginseng of Kon Tum and Quảng Nam provinces. However, in fact, Ngọc Linh Ginseng is not limited to in geographical area as specified  in Decision No. 3235/QD-SHTT. This is the center with altitude of 1800 - 2500 meter and organic matter layer of over 18 centimeter thickness which are the most suitable conditions for ginseng development with the best quality. In reality, the production area of Ngọc Linh Ginseng in Kon Tum and Quảng Nam is exceeded the announced GI area and is still in area of Ngọc Linh mountain with similar natural conditions, production practices and variety of ginseng to the announced GI. Therefore, on 22 June 2018, Kon Tum’s Department of Science and Technology, with the authorization of Quảng Nam’s Department of Science and Technology, filed request for amendments of GI Registration Certificate No. 00049 regarding peculiar characteristics and product quality as well as expansion of  geographical area. On 30 July 2018, Director General of the NOIP  issued Decision No. 2465/QD-SHTT on the amendments of GI Registration Certificate No. 00049. This Decision has replaced Decision No. 3235/QD-SHTT dated 16 August 2016 of  Director General of the NOIP on granting the GI Registration Certificate of Ngọc Linh for ginseng.

Ngọc Linh Ginseng has straight posture with green or slightly purple colour. Its root has multiple nodes and curves with length of around 3.5 – 10.5 centimeter and diameter of around 0.5 – 2.0 centimeter. The outer surface of gingseng has brown or yellowish grey colour. The tuberous root has a spindle shape with 2.4 – 4 centimeter long and diameter of 1.5 – 2 centimeter. The tuberous root’s colour is slightly brown, it also features horizontal edges and rootlet nodes. It has a solid body which is hard to break.

Average weights of fresh and dried ginsengs are increased by age. Specifically, average weight of 4-year-old whole rootlets fresh ginseng is 14.20g; 5-year-old’s is 16.78g; 6-year-old’s is 19.63g; 7-year-old’s is 22.78g; 8-year-old’s is 24.40g; 9-year-old’s is 26.70g; 10-year-old’s is 28.68g; 15-year-old’s is 31.60g. Average weight of 4-year-old dried ginseng is 4.13g; 5-year-old’s is 4.58g; 6-year-old’s is 5.54g; 7-year-old’s is 6.92g; 8-year-old’s is 7.53g; 9-year-old’s is 7.83g; 10-year-old’s is 8.71g; 15-year-old’s is 9.47g.

 

The quality of ginseng is evaluated by  criteria related to saponin content. Whole saponin content and  content of main compositions of saponin of Ngọc Linh Ginseng also tend to increase with its age. Specifically, the average content of whole saponin of 4-year-old ginseng is 7.15 ± 0.1411%; 5-year-old’s is 8.91 ± 0.1375%; 6-year-old’s is 10.67 ± 0.2792%; 7-year-old’s is 12.43 ± 0.2984%; 8-year-old’s is 14.19 ± 0.0158%; 9-year-old’s is 15.94 ± 0.2862%; 10-year-old’s is 19.75 ± 0.2712%; 15-year-old’s is 19.93 ± 0.7299%. The contents of main compositions of saponin including R2 (MR2), Gingsenosid Rg1 (G-Rg1), Gingsenosid Rb1 (G-Rb1) in 4-year-old ginseng are: MR2: 2.04±0.0024%;  G-Rg1: 1.11±0.0032%;  G-Rb1: 0.73±0.0103%; 5-year-old’s are: MR2: 3.02±0.1762%;  G-Rg1: 1.30±0.0347%;  G-Rb1: 0.75±0.0398%; 6-year-old’s are: MR2: 3.62±0.1027%;  G-Rg1: 1.63±0.0478%;  G-Rb1: 0.88±0.0386%; 7-year-old’s are: MR2: 4.35±0.0399%;  G-Rg1: 2.33±0.0439%;  G-Rb1: 0.89±0.0212%; 8-year-old’s are: MR2: 4.96±0.0606%;  G-Rg1: 2.53±0.0786%;  G-Rb1: 0.95±0.0117%; 9-year-old’s are: MR2: 5.58±0.0768%;  G-Rg1: 2.73±0.0965%;  G-Rb1: 1.12±0.0764%; 10-year-old’s are: MR2: 7.46±0.0176%;  G-Rg1: 3.26±0.0398%;  G-Rb1: 1.58±0.1070%; 15-year-old’s are: MR2: 7.97±0.0391%;  G-Rg1: 4.17±0.0388%;  G-Rb1: 1.96±0.0234%.
