| Judul Artikel | Perbandingan Morfologi, Epidermis, dan Kandungan Flavonoid Gempur Batu Daun Hijau dan Ungu (Pararuellia napifera (Zoll.) Bremek. & Nann.-Bremek) |
| Abstrak (Bhs. Indonesia) | Gempur batu (Pararuellia napifera (Zoll.) Bremek. & Nann.-Bremek) merupakan tanaman herba dari famili Acanthaceae yang memiliki variasi warna daun hijau dan ungu. Perbedaan warna daun tersebut diduga berkaitan dengan variasi karakter morfologi, struktur epidermis, serta akumuluasi metabolit sekunder terutama flavonoid. Variasi morfologi dan struktur epidermis seperti bentuk dan ukuran daun, tepi daun, tipe dan kerapatan stomata, serta tipe trikoma berpotensi mencerminkan perbedaan fisiologis antar variasi warna daun. Penelitian ini bertujuan untuk mengetahui perbedaan karakter morfologi, struktur epidermis, dan kandungan flavonoid pada gempur batu daun hijau dan daun ungu. Penelitian dilakasanakan menggunakan metode purposive sampling dan eksperimen dengan Rancangan Acak Lengkap (RAL), yaitu warna daun yang terdiri atas dua taraf, yaitu daun hijau dan daun ungu, dengan masing-masing tiga ulangan. Parameter yang diamati meliputi karakter morfologi organ tanaman (akar, batang, dan daun), struktur epidermis daun yang meliputi ketebalan epidermis, trikoma, tipe dan kerapatan stomata, serta kadar total flavonoid yang dianalisis menggunakan metode spektrofotometri UV-Vis dengan larutan standar kuersetin. Data dianalisis menggunakan uji t (independent sample t-test) pada taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa P. napifera berdaun hijau dan ungu menunjukkan perbedaan pada beberapa karakter morfologi, struktur epidermis, dan kandungan flavonoid. Perbedaan karakter morfologi terutama ditunjukkan pada warna akar, batang, dan daun serta bentuk ujung daun, sedangkan karakter morfologi lainnya relatif serupa. Struktur epidermis daun P. napifera berdaun hijau dan ungu menunjukkan perbedaan pada kerapatan stomata, sedangkan ketebalan epidermis tidak menunjukkan perbedaan yang signifikan. Tipe stomata dan trikoma yang ditemukan pada kedua tipe warna daun juga menunjukkan karakter yang sama. Kandungan flavonoid total pada akar dan daun menunjukkan perbedaan yang signifikan antara P. napifera berdaun hijau dan ungu, sedangkan kandungan flavonoid pada batang cenderung serupa. Kandungan flavonoid total tertinggi ditemukan pada daun pada kedua tipe warna. |
| Abtrak (Bhs. Inggris) | Gempur batu (Pararuellia napifera (Zoll.) Bremek. & Nann.-Bremek) is a herbaceous plant belonging to the family Acanthaceae that exhibits variations in leaf color, namely green and purple. Differences in leaf color are presumed to be associated with variations in morphological characteristics, epidermal stucture, and the accumulation of secondary metabolites, particularly flavonoids. Variations in morphological and epidermal characteristics, such as leaf shape and size, leaf margin, stomatal type and density, and trichome type, may reflect physiological differences between plants with different leaf colors. This study aimed to determine differences in morphological characteristics, epidermal structure, and flavonoid content between green and purple leaved P. napifera. The study was conducted using a purposive sampling method and an experiment with a Completely Randomized Design (CRD), consisting of two leaf color treatments, namely green and purple leaves, with three replicates for each treatment. The observed parameters included the morphological characteristics of plants organs (roots, stems, and leaves), leaf epidermal structures comprising epidermal thickness, trichomes, stomatal type and density, and total flavonoid content analyzed using UV-Vis spectrophotometry with quercetin as the standard solution. The data were analyzed using an independent samples t-test at a 5% significance level. The results showed that green and purple leaved P. napifera differed in several morphological characteristics, epidermal structures, and flavonoid content. The morphological differences were mainly observed in the color of the roots, stems, and leaves, as well as the shape of the leaf apex, whereas the other morphological characteristics were relatively similar. The leaf epidermal structure differed in stomatal density, while epidermal thickness did not differ significantly, and the trichome and stomatal types were similar between the two leaf color types. Statistical analysis showed that the total flavonoid content in the roots and leaves of green leaved P. napifera differed significantly from that of purple leaved P. napifera, whereas no significant difference was observed in the stems. The highest total flavonoid content was found in the leaves. |
