Abstract

North Kalimantan is home to a unique biodiversity, including medicinal plants traditionally used by local communities such as the Dayak people. Several of these plants are endemic—found exclusively in this region. Two notable endemic species, Dayak onion (Eleutherine palmifolia (L.) Merr.) and rose myrtle (Rhodomyrtus tomentosa), are known to contain secondary metabolites, including phenolic compounds. This study aimed to determine the total phenolic content of these two endemic plants. Extraction was performed using Ultrasonic-Assisted Extraction (UAE), resulting in extract yields of 11.42% (11.42 g) for Dayak onion and 24.33% (24.33 g) for rose myrtle. Preliminary phytochemical screening using 1% FeCl₃ reagent indicated the presence of phenolic compounds, evidenced by a color change to bluish-green or dark green. The quantitative analysis was performed using UV–Vis spectrophotometry at a wavelength of 752 nm, applying the Folin–Ciocalteu method with gallic acid as the standard. The results showed that Dayak onion extract contained 1.410 mg GAE/g extract (0.141%), while rose myrtle extract contained 2.259 mg GAE/g extract (0.2259%) of total phenolic compounds. These findings highlight the phenolic potential of endemic medicinal plants from North Kalimantan and support their further exploration for pharmacological and nutraceutical applications

Abstract

Labu kuning (Cucurbita moscata) adalah tanaman tropis dan salah satu  komoditas pertanian unggulan di kecamatan Bontonompo, kabupaten Gowa, Sulawesi Selatan. Buah labu  bernilai ekonomis dan dijadikan sayur mayur, dan bahan olahan pangan lainnya. Namun daunnya  hanya terbuang jadi limbah karena kurangnya pengetahuan oleh masyarakat setempat akan manfaatnya sebagai bahan baku obat alam, padahal daun labu kuning memiliki kandungan metabolit sekunder seperti flavonoid, tokoferol, fenol, yang memiliki efek antioksidan, antibakteri, antidiabetik, antikolesterol. Untuk menjamin kualitas bahan baku  produk bahan alam, maka diperlukan  pengujian mutu. Tujuan penelitian ini untuk menganalisis mutu fisik ekstak daun labu kuning asal Bontonompo. Metode penelitian dimulai dengan mengekstraksi daun labu kuning menggunakan  etanol encer 70% metode Ultrasonic Assisted Extraction (UAE) yang dikompilasi dengan perendaman selama 2 jam, ekstrak kental hasil penguapan dengan rotavapor lalu diuji parameter fisik terdiri dari penentuan identitas ekstrak, uji organoleptik, penetapan kadar air, dan berat jenis.  Hasil ekstraksi  daun labu kuning didapatkan nilai rendemen ekstrak 21,68%. Identitas ekstrak dengan nama ekstrak Curcubitae Folium Extractum. Hasil parameter mutu fisik ekstrak secara organoleptik dengan bentuk ekstrak kental, higroskopik, mirip pasta, warna hitam,  bau tidak berbau, rasa pahit. Data berat jenis yang didapatkan sebesar 0,99, dan  kadar air adalah 0,82%. Data parameter fisis ekstrak daun labu kuning merupakan pedoman dasar dan Langkah awal dalam standarisasi bahan baku bahan alam yang akan dikembangkan menjadi produk farmasi yang bermutu.
