Antioxidant and alpha-amylase inhibitory study of Sansevieria trifasciata Prain. leaves extract

Diabetes is one of the chronic diseases whose prevalence is increasing all over the world, including in Indonesia. Diabetes mellitus is characterized by high blood glucose levels that can be overcome by, for instance, inhibiting the alpha-amylase enzymes that play a role in carbohydrate hydrolysis. Several studies have proved that active antioxidant substances can also support the treatment of diabetic patients. Snake plant (Sansevieria trifasciata Prain.), or locally known as lidah mertua in Indonesia, is a traditional herbal used to treat diabetes. This study investigated the activity of the ethanol extract of S. trifasciata leaves in inhibiting α-amylase. The leaves were extracted by maceration with ethanol 70%, followed by phytochemical screening. The antioxidant activity was determined using the DPPH method, while the inhibition of α-amylase was measured using UV-Vis spectrophotometer at 524nm wavelength. The results showed that IC50 of the antioxidant activity was 1527.55 ppm, five times greater than the positive control, i.e., vitamin C. In the case of α-amylase enzyme, the IC50 of the ethanol extract of S. trifasciata leaves was 158.31 μg/ml and 0.26 times more potential than acarbose. The study has proved that the crude extract of S. trifasciata leaves has the potential as one of the antidiabetics and antioxidants that can be studied further

Artocarpus altilis Leaves Activity in Inhibiting α-Amylase Enzyme as Oral Antidiabetic Drug Candidate

Background: The search for effective antidiabetic drugs remains to be a focus of research in the world. Artocarpus have been used as traditional medicine in South-East Asia. One of the species, Artocarpus altilis has been known in Indonesia as traditional treatment for diabetic. Objective: This research aimed to discover α-amylase inhibitor activity of Artocarpus altilis leaves. Methods: Leaves were extracted by maceration method, followed by phytochemical screening and quercetin identification using LC-MS method. Inhibition of α-amylase was measured using UV-Vis spectrophotometer at 524 nm wavelength, while antioxidant activity was determined using DPPH. Results: Artocarpus altilis leaves ethanol extract exhibited activity against α-amylase with 155.96 ppm IC50 (0.27 times relative potential compared to acarbose) and the extract showed antioxidant activity with the IC50 of 999.96 ppm. Conclusion: Artocarpus altilis showed activity as the α-amylase inhibitor

Exploration, phenolic content determination, and antioxidant activity of dominant pteridophytes in Gunung Malang Village, Mount Halimun Salak National Park, Indonesia

Rindita, Anggia V, Rahmaesa E, Devi RK, Alawiyah LF. 2020. Exploration, phenolic content determination, and antioxidant activity of dominant pteridophytes in Gunung Malang Village, Mount Halimun Salak National Park, Indonesia. Biodiversitas 21: 3676- 3682. Pteridophytes have been known to have pharmacological activities as an antioxidant, anti-inflammation, antimicrobials, and anticancer, such as Selaginella sp. In this research, exploration was conducted in Gunung Malang Village, Mount Halimun Salak National Park (TNGHS), West Java. Samples were collected by purposive sampling method, related to its abundant populations, Histiopteris incisa, Nephrolepis biserrata, and Selaginella willdenowii were collected based on different height and light intensity. Abiotic factors were measured to know their ecological requirements. Samples were extracted using ultrasonic method. Organoleptic test, yield, and phytochemical screening were done for the crudes extract. Total phenolic level was determined with Folin-Ciocalteu method and antioxidant activity test with DPPH. Phytochemical screening showed that H. incisa contains phenolics, saponins, tannins, and steroids; N. biserrata contains phenolics, flavonoids, and saponins while S. willdenowii contains phenolics, alkaloids, flavonoids, saponins, and tannins. Phenolic content of H. incisa and N. biserrata from 700 m. asl.was 9.8523 mg GAE/g ± 0.9694 and 17.5399 mg GAE/g ± 0.5350 respectively, from 1000 m. asl. was 18.1231 mgGAE/g ±2.1535 and 8.8468 mg GAE/g ± 0.1437. S. willdenowii extract collected from shaded canopy forest was 19.2324 mg GAE/g ± 0.6041 and opened canopy forest was 38.7087 mg GAE/g ± 1.484. Antioxidant IC50 of H. incisa and N. biserrata from 700 m. asl. respectively was 96.4271 ppm and 85.1907 ppm, while from 1000 m. asl. was 75.6381 ppm and 95.0678 ppm, S. willdenowii from the closed canopy is 101.7326 ppm, while from the opened canopy was 92.0998 ppm. This study shows that all ferns tested gave significant antioxidant activity and was influenced by environmental factors

Evaluasi Fitokimia dan Antioksidan dari Piper hispidum Sw. yang dikoleksi dari Desa Gunung Malang pada Vegetasi yang Berbeda

Jamaican pepper (Piper hispidum Sw.) is a wild plant, member of Piperaceae family and invasive plant species reported used to heal wounds and treat symptoms of skin leishmaniasis. This study aims to explore phytochemicals of Piper hispidum, especially phenolic content and antioxidant capacity, in two different abiotic condition of the forest, shaded and open area. Exploration of P. hispidum was conducted in Gunung Malang Village, Halimun Salak Mountain National Park (TNGHS). The sample was extracted with the ultrasonic method. The phenolic level and antioxidant activity were determined with Folin Ciocalteu and DPPH method where gallic acid was used as a standard. The total phenolic content assay showed 70% ethanol extract of P. hispidum Sw. leaves from the shaded and open forest were 17.4775 mg GAE/g and 12.6137 mg GAE/g of sample respectively. The antioxidant activity assay showed that IC50 of the sample from shaded and open forest were 94.8414 and 94.3412 ppm and gallic acid was 7.9817 ppm. This study showed that differences in vegetation and environmental abiotic factor may contributed in the amount of chemical compounds where open vegetation exposed to the sunlight had lower values than shaded but not significantly affected the antioxidant value.Jamaican pepper (Piper hispidum Sw.) adalah anggota Piperaceae, tumbuhan liar, dan merupakan jenis tumbuhan invasif yang dilaporkan digunakan untuk menyembuhkan luka dan mengobati gejala leishmaniasis kulit. Penelitian ini bertujuan untuk mengetahui kandungan fitokimia, khususnya kadar fenolik dan aktivitas antioksidan Piper hispidum di dua kondisi abiotik yang berbeda di dalam hutan, yaitu hutan terbuka dan hutan ternanungi. Eksplorasi dilakukan di Desa Gunung Malang, Taman Nasional Gunung Halimun Salak (TNGHS). Metode ekstraksi menggunakan ultrasonik, asam galat sebagai pembanding pada pengujian fenol dan metode DPPH untuk pengujian antioksidannya. Hasil uji kandungan total fenol menunjukkan ekstrak etanol 70% daun P. hispidum Sw. yang ternaung adalah 17,4775 mg GAE/g dan di hutan terbuka adalah 12,6137 mg GAE/g sampel. Uji aktivitas antioksidan menunjukkan bahwa IC50 dari vegetasi tertutup dan terbuka berturut-turut adalah 94,8414 dan 94,3412 ppm dan serta asam galat sebagai pembanding sebesar 7,9817 ppm. Hasil penelitian menunjukkan bahwa perbedaan vegetasi dan faktor biotik dan abiotik dapat mempengaruhi perbedaan kadar senyawa kimia, nilai uji fenol vegetasi terbuka dan terpapar matahari memiliki nilai yang lebih rendah dibanding ternanung tetapi tidak signifikan mempengaruhi kapasitas antioksidan
