Abstract. Batubara R, Hanum TI, Affandi O, Julianti E, Ulfa M. 2022. The antioxidant activities and chemical compounds of Aquilaria crassna, Aquilaria microcarpa, and Gyrinops versteegii leaves growing in Langkat, North Sumatra, Indonesia. Biodiversitas 23: 6619-6628. Agarwood has been cultivated for its wood and leaves in Indonesia. This research aims to determine the potential of the leaves of Aquilaria crassna, A. microcarpa, and Gyrinops versteegii that grow in Langkat as raw materials for antioxidant-rich tea based on their chemical compounds and antioxidant activities. The leaf powder was extracted using ethanol. Bioactive compounds were analyzed by GC-MS, while the antioxidant activity was analyzed by the DPPH method. The results showed that A. crassna leaves contained alkaloids, flavonoids, tannins, steroid/triterpenoid dan glycosides, whereas A. microcarpa leaves contained alkaloids, tannins, saponins, steroid/triterpenoid dan glycosides alkaloids, tannins, and triterpenoids. In comparison, G. versteegii leaves contained flavonoids, tannins, saponins, steroid/triterpenoids, and glycosides. The IC50 values of ethanol extract of A. crassna, A. microcarpa, and G. versteegii leaves were 30.0079, 29.3263, and 31.6304 µg/mL, respectively. The highest chemical compounds of A. crassna, A. microcarpa, and G. versteegii were Cyano, -acetic acid, 1,2,3,4-Cyclopentane Petrol, and Oxacycloheptadec-8-en-2-one Ambrettolide The three species had high antioxidant activity; therefore they are potential sources of antioxidants.

Abstract. Batubara R, Hanum TI, Affandi O, Nurminah M, Winarni I, Hannum S, Yasmin OY, Chery SC, Dalimunte A. 2025. Proximate and phytochemical analysis of Acanthus ilicifolius hot water extract from three different growing locations. Biodiversitas 26: 1641-1651. Jeruju (Acanthus ilicifolius) is a tide-dependent plant and often obtains more freshwater supply. The chemical composition of this plant needs to be explored so that consumers can obtain the required information, particularly regarding the use of A. ilicifolius hot water extract. Therefore, this research aimed to determine proximate and phytochemical content of A. ilicifolius from three different growing locations. Proximate analysis was carried out by testing water, ash, fat, and protein composition, while phytochemical tests and GC-MS (Gas Chromatography Mass Spectrometry) were used to determine the number and names of chemical compounds, respectively. The results showed that ash, fat, and protein composition of A. ilicifolius from the three sample locations were not statistically different. Based on SNI 3945-2016 and SNI 01-4453-1998, water content met the standard of 2.11-7.47%, while ash content did not fulfill the requirement of 0.56-0.59%. Fat and protein content ranging from 8.58 to 10.22% and 19 to 19.95% had no standard specification. Phytochemical test results of hot water extract showed that the compounds from the three sample locations were the same, including flavonoids, glycosides, steroids, triterpenoids, saponins, and tannins. Based on GC-MS, the main compound in hot water extract of A. ilicifolius sampled from Pasar Rawa Village was 2(3H)-Benzoxazolone. In comparison, the main compounds from Percut Village and Paya Pasir Village were found to be dodecanoic acid, 1,2,3-propanediol ester, and dodecyl palmitate.

Abstract

Penelitian ini bertujuan untuk memberikan pemahaman praktis kepada siswa mengenai penggunaan tanaman iler dalam penyembuhan luka serta untuk meningkatkan keterampilan mereka dalam meracik sediaan farmasi. Metode pelatihan melibatkan sesi teori yang mencakup informasi tentang sifat-sifat tanaman iler, teknik ekstraksi bahan aktifnya, formulasi sediaan obat, dan praktik langsung dalam pembuatan serta pengujian efektivitas obat luka yang dihasilkan. SMA Negeri 1 Perbaungan dipilih sebagai lokasi pelaksanaan karena keberadaan tanaman iler yang melimpah di sekitarnya, memungkinkan integrasi pengetahuan teori dengan pengalaman langsung dalam memanfaatkannya. Pelatihan berfokus pada pendekatan praktis dengan siswa terlibat dalam setiap tahap produksi sediaan obat, mulai dari pengumpulan sampai penggunaan akhirnya dalam proses penyembuhan luka. Hasil evaluasi menunjukkan peningkatan signifikan dalam keterampilan siswa dalam meracik sediaan farmasi dengan tanaman iler. Mereka memperoleh pemahaman yang lebih baik tentang proses ekstraksi dan formulasi obat serta keterampilan praktis dalam pembuatan sediaan yang efektif untuk pengobatan luka. Dengan mengintegrasikan pendekatan ini ke dalam kurikulum, diharapkan siswa dapat mengaplikasikan pengetahuan dan keterampilan yang mereka peroleh dalam konteks nyata, mendorong inovasi dalam pengobatan tradisional berbasis tanaman.
