Community service activities carried out by students of Universitas Jenderal Achmad Yani were carried out on August 29, 2022, taking place in a medicinal plant garden, Faculty of Pharmacy, Universitas Jenderal Achmad Yani which was attended by UMKM Spice Nusantara Bandung participants. The socialization carried out was the presentation and delivery of post-harvest processing materials (wet sorting, washing, drying, and dry sorting) and the standardization of traditional raw materials. Conventional medicine is a form of treatment efforts in the community to support health which is currently being recommended by the government. Communities can use the toga as an economical and efficient measure to maintain body immunity because the community can obtain and use the toga quickly and simply to maintain family health. The postharvest process greatly determines the existence of active compounds that are efficacious for treatment. Incorrect postharvest management can change, reduce, or destroy the active substance of a plant into a substance that has no therapeutic effect and can even endanger health. The results of the participant's level of understanding were carried out post-test with the results of what is the purpose of post-harvest processing (100%), the sequence of post-harvest processing (80%), what is the general drying temperature (100%), a medicinal plant has good quality and efficacy then we need to know (80%), and what is the function of the washing process (90%) with the conclusion that socialization activities can significantly increase the knowledge of participants from MSMEs regarding planting, post-harvest processing, and the properties of medicinal plants significantly.
telah diisolasi dari fraksi etil asetat berdasarkan sitotoksik tertinggi dengan nilai LC50 3.69 µg/mL. Senyawa yang diisolasi diuraikan untuk mendapatkan basis struktur kimia pada data spektroskopik (UV-Vis Spektrofotometrik, IR Spektrofotometrik, dan NMR). Toksisitas fraksidin diuji dengan BSLT dan tidak menunjukkan potensi aktivitas dengan nilai LC50 > 500 μg/mL.
The Pangandaran people process honje flowers into fresh drinks that are consumed for health. Theforest honje leaf extract provides antidiabetic activity at a dose of 0.39 mg/g BW can reduce bloodglucose levels by 36.16% has been reported. Limited scientific information from honje hutan flowers,it is necessary on its activity as an alpha-glucosidase inhibitor and study its chemical content. Theextraction process was macerated in 70% ethanol for 24 hours and the fractionation process wascarried out by liquid-liquid extraction method with n-hexane, ethyl acetate and water as solvents.Testing the activity of alpha-glucosidase inhibitors colorimetrically using the chromogenic substratep-nitrophenyl α-D-glucopyranoside, alpha-glucosidase enzymes derived from Saccharomycescerevisiae, measurement of absorption at a maximum wavelength of 401.3 nm and acarbose usedas a comparison drug alpha-glucosidase inhibitors. The results showed that the forest honje flowerscontain flavonoids, polyphenols, tannins, quinones, monoterpenoids, and sesquiterpenoids. IC50 valuesfor 70% ethanol extract, n-hexane, ethyl acetate, water and acarbose fractions were 136.79, 307.18,277.12, 66.18, and 14.63 g/mL respectively. The water fraction gave the best inhibitory activity againstalpha-glucosidase with an IC50 value of 66.18 g/mL.Keywords: Etlingera hemisphaerica (Blume) R.M.Sm, honje hutan flowers, alpha-glucosidaseinhibitor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
