Background: The quality of a medicinal plant is influenced by agronomic conditions and harvesting time. Objective: This study aimed to evaluate the effect of planting method (openair (OA) and shedding house (SH)) and harvesting time (2, 4, 6 months) of Lampeni (Ardisia humilis Vahl.) toward the inhibitory activity of alpha-glucosidase. Methods: The Lampeni seedling were placed under controlled light conditions (SH) and on direct sun exposure (OA). Harvesting of the leaves was carried out at the age of 2, 4, and 6 months after plantation (2m, 4m, and 6m). Each leaves dry powder was refluxed with methanol 70\% and followed by liquid-liquid partition using n-hexane, ethyl acetate (EtOAc), and water. All samples were evaluated toward inhibition of the alpha-glucosidase enzyme in vitro. Total phenol levels were determined using Folin-Ciocalteu reagent. Results: The results showed that EtOAc fractions of both plantation techniques exhibited the highest inhibition of alpha-glucosidase. The highest activity was demonstrated by the 4m-OA-EtOAc fraction (IC50, 93.50 ppm) and followed by the 6m-OA-EtOAc fraction (IC50, 98.13 ppm). Based on the kinetic study, the inhibition type of the two most active samples were categorized as a non-competitive type. Total phenolic contents were decreased in the following order: 6m-SH-EtOAc \> 4m-OA-EtOAc \> 6m-OAEtOAc \> 4m-SH-EtOAc fraction. It was shown that there was no positive correlation between the strength of inhibition with total phenolic content. Conclusions: This study concluded that Lampeni at open-air plantation harvested on fourth months demonstrated the highest alpha-glucosidase inhibitory activity, although there was no positive correlation between the inhibition activity and phenolic content.

Introduction: Hypertension is a leading problem in Indonesia, because of the high prevalence and the long term effect. Bitter melon leaves (Momordica charantia L.) has been traditionally utilized to treat hypertension, yet not many studies explained the antihypertension effect of this plant. Methods: This study was conducted to test the benefit of bitter melon leaves as antihypertension using angiotensin converting enzyme inhibition activity in 80\% ethanolic extract and its fractions (n-hexane, ethyl acetate, and n-butanol) using ACE kit-WST (Dojindo, Japan). Then the antihypertension activity was associated with the phenolic content which was expressed in gallic acid equivalent (GAE) and total flavonoid in quercetin equivalent (QE). Results: Result of the study showed that the IC50 value obtained from the ethanolic extract to inhibit ACE activity was 7.52 \μg/mL and the highest inhibition obtained in ethyl acetate fraction with IC50 value was 4,29 \μg/mL. Phenolic total and flavonoid total determination also showed that the highest content obtained in ethyl acetate fraction with 18.752 mg GAE/gr extract and 8.310 mg QE/gr extract, respectively. Conclusion: According to the study, it could be concluded that bitter melon (Momordica charantia L.) leaves provide inhibition activity against Angiotensin Converting Enzyme (ACE) and chemical compounds that were expected to play an active role in inhibiting ACE were flavonoid and tannin.
