“…Gambir (Uncaria gambir Roxb) is one species from the Rubiaceae family that is widely grown in Indonesia and has the potential to be a medicine. 1 Gambir is a typical plant produced in four provinces in Indonesia, namely West Sumatra, North Sumatra, Riau, and South Sumatra. 2 However, as much as 90% of the gambir in Indonesia is produced in West Sumatra.…”

Gambir (Uncaria gambir Roxb) has long been thought to provide various health benefits due to the main secondary metabolite, catechin. The high catechin content makes gambir a strong antioxidant. The present study was conducted to develop and validate the quantification of catechin in gambir leaves by high-performance liquid chromatography (HPLC). The method was performed using a 100 mL sample with dilution. The separation process employed a Sunfire C18 (150 mm × 4.6 mm) column, the mobile phase was composed of solvent A: 0.03% trifluoroacetic acid in acetonitrile-water (5:95) and solvent B: 0.1% trifluoroacetic acid in acetonitrile at a 0.45 mL/min flow rate. The validation was conducted by measuring the accuracy, precision, linearity, limit of detection (LOD), limit of quantification (LOQ), and robustness. The results showed that the percent recovery was 98.30-99.82% with a precision value of 0.28% RSD, good linearity with a 0.9996 R-value, 2.7 µg/mL of LOD, and 8.3 µg/mL of LOQ. There was no significant difference between changes in the mobile phase of 4% (comparison of area and retention time), and 6% (comparison of area). However, the results also demonstrated that the mobile phase was not resistant to changes in the mobile phase of 6% in the ratio of retention time because of the shift in retention time that was faster than the catechin standard. The findings of this study reveal that this method satisfies the validation requirements for accuracy, precision, linearity, and robustness tests, therefore, the HPLC-based method can be applied to analyze catechin in gambir leaves.

Gambir (Uncaria Gambir Roxb.) is one of the non-timber forest product commodities developed by Pakpak Bharat society has beneficial for the health and raw materials of the industry. This research aims to determine the contribution of gambir to the local economy, identifying the district production base of gambir commodities as well as characteristics of spreading gambir commodities to support the economic development of the Pakpak Bharat District. The study was using secondary data of time series from 2015 to 2019. Location Quotient (LQ) was used for localization and specialization analysis, as well as for basic service ratio (BSR) and regional multiplier (RM) analysis. The results showed that the region of the gambir commodity base based on the production indicator consists of Salak subdistrict, Sitellu Tali Urung Jehe sub-district, Pergetteng Getteng Sengkut sub-district, and Tinada sub-district. The gambir community forest is not concentrated in one region but is scattered in several sub-districts. Pakpak Bharat District also does not specialize in gambir community forest. Gambir commodities can support plantation activities and the regional economy in Pakpak Bharat District. The existence of the gambir community forest supports economic activity in the form of the multiplier effect generated for the sub-districts in Pakpak Bharat District. The multiplier effect is generated in the form of increasing community income and the absorption of manpower both in the plantation subsectors and other sectors.
