“…These findings were in line with the function of the garden as an important location for the process of plant domestication and also the development and cultivation of economic value crops (Miller and Nair 2006;Ashagre et al 2015). F. rukam fruits contain other secondary metabolites which were very useful for medicinal purposes such as saponins, flavonoids, polyphenols, and tannins (Barcelo 2015). This fruit became a source of fruit for tribal of Anak Dalam in Jambi (Setyowati 2003).…”

Silalahi M, Nisyawati. 2018. The ethnobotanical study of edible and medicinal plants in the home garden of Batak Karo subethnic in North Sumatra, Indonesia. Biodiversitas 19: 229-238. The cultivation of plants in home gardens for self-sufficiency is a long tradition in Karo District, but the documentation of local knowledge about edible and medicinal plants in home gardens in Karo District is limited. This study aimed to (i) document the uses of the edible and medicinal plants in home gardens; (ii) to analyze the diversity of edible and medicinal plants in home gardens. Data were collected using the ethnobotanical surveys and interviews methods. The Shannon Weiner and Margalef indices were calculated to determine the diversity levels of medicinal and edible species in the home gardens of Karo ethnic. The surveys were conducted in 30 home gardens (7 villages), Karo District, North Sumatra. The 85 recorded species belonged to 43 families, and 73 genera were used as edible and medicinal plants. The plants studied in the home gardens used for human consumption were i.e. fruits, vegetables, spices, tubers and medicinal plants. Among 85 plant species growing in home gardens, 52 species were cultivated, and the rest were semi cultivated. Home gardens had the Shannon Wiener index ranging from 1.164 to 3.123 while Margalef index ranging from 0.929-2.531.

The RFS extract solution and pancreatic elastase (PPE) were mixed in Trizma®-HCl buffer (pH 8.0), then pre-incubated at 25 o C for 5 min. Substrate N-Succinyl-Ala-Ala-Ala-p-nitroanilide (SANA) was added to the mixture and incubated at 25 o C for 20 min in 96-well microplate (Nunc). The optical density due to the formation of p-nitroaniline was ABSTRACT Introduction: Some Rubus were reported had anti-skin aging activity. Rubus fraxinifolius was one of Rubus genus which lives in Indonesian highland. Objective: This study was to examine elastase, tyrosinase, and oxidant inhibitory activity of R. fraxinifolius stem (RFS) extract. Methods: Extraction was done by a Soxhlet apparatus using methanol as solvent. Elastase inhibition activity was determined, which based on the formation of p-nitroaniline. Tyrosinase inhibition activity evaluated based on inhibition of mushroom tyrosinase by the sample with L-DOPA as substrate. The activity of antioxidant was determined using the DPPH radical scavenger method. LC-MS was used for prediction of naturally occurring phytochemicals. Results: The RFS extract yield was 9.03 %. The RFS extract revealed inhibition activity against elastase and tyrosinase with IC 50 128.85 ppm, and 155.19 ppm, respectively. DPPH radical scavenging activity gave IC 50 63.04 ppm. Total phenolic content of the extract was 387.99+3.21 mg GAE/g extract. The LC-MS analysis showed the presence of at least 13 different organic compounds in RFS extract, which might contribute to the bioactivity. Conclusion: Therefore, this experiment further proved that RFS extract might be useful as a natural product ingredient of anti-photoaging skincare products because of its ability to inhibit elastase, tyrosinase, and as an antioxidant.

“…Dari hasil penelitian (Gambar 2) menunjukkan bahwa kandungan polifenolat tertinggi diperoleh dari daun dengan metode ekstraksi menggunakan Soxhlet. Sementara bagian buah R. fraxinifolius mengandung lebih sedikit polifenolat, hal ini sesuai dengan beberapa penelitian lainnya (3,10) . Kandungan polifenolat dari buah R. fraxinifolius terutama dari golongan antosianin, elagitanin, serta proantosianidin (10) .…”

Rubus fraxinifolius can be founded in the mountainous regions of West Java. Previous studies have shown that this plant has potent antioxidant activity. The content of polyphenol compounds in this species contributes substantially to antioxidant activity, and the extraction method will aff ect the content of the compound. In this study, an evaluation of the extraction method eff ect on leaves, young fruits, and stems of R. fraxinifolius on the content of polyphenols and their antioxidant activity, have been done. The leaves, fruits, and stems of R. fraxinifolius were extracted by maceration, refl ux, and Soxhlet using methanol as a solvent. Each extract was determined the total polyphenol content using Folin-Ciocalteu reagent and antioxidant activity test using DPPH reduction method. The highest extract yield was R. fraxinifolius leaf refl ux extract (30.20%). The highest total polyphenol content was given by the Soxhlet extract of leaf R. fraxinifolius (48.79 mg GAE/g extract). The highest antioxidant activity was leaf Soxhlet extract of R. fraxinifolius (98.29% at 100 ppm). From this study it was shown that the methanol extract of R. fraxinifolius leaves extracted by soxhlet gave the highest polyphenol content and antioxidant activity.Abstrak: Tanaman Rubus fraxinifolius dapat ditemukan di daerah pegunungan Jawa Barat. Penelitian sebelumnya menunjukkan bahwa tanaman ini memiliki aktivitas antioksidan yang sangat kuat. Kandungan senyawa polifenol pada tanaman berkontribusi secara substansial terhadap aktivitas antioksidan dan metode ekstraksi akan mempengaruhi kandungan senyawa yang tersari. Pada penelitian ini dilakukan evaluasi pengaruh metode ekstraksi organ daun, buah muda, dan batang R. fraxinifolius terhadap kandungan polifenol serta aktivitas antioksidannya. Bagian daun, buah, dan batang R. fraxinifolius diekstraksi cair padat secara maserasi, refl uks, dan Soxhlet menggunakan pelarut metanol. Terhadap masing-masing ekstrak dilakukan penetapan kadar polifenol total dengan pereaksi Folin-Ciocalteu serta uji aktivitas antioksidan dengan metode peredaman DPPH. Rendemen ekstrak terbanyak adalah ekstrak refl uks daun R. fraxinifolius sebesar 30,20%. Kandungan polifenol total tertinggi adalah pada ekstrak Soxhlet daun R. fraxinifolius sebesar 48,79 mg GAE/g ekstrak. Aktivitas antioksidan tertinggi yaitu ekstrak Soxhlet daun R. fraxinifolius sebesar 98,29% pada 100 bpj. Dari penelitian ini menunjukan bahwa ekstrak metanol daun R. fraxinifolius yang diekstraksi secara Soxhlet memiliki kandungan polifenol serta aktivitas antioksidan tertinggi.Kata kunci: Rubus fraxinifolius, metode ekstraksi, rendemen, polifenolat, antioksidan.
