“…Apart from these, TCs were also determined where leaf extracts in spring season of Ungma were found to be the highest. Tannins are naturally occurring water-soluble plant polyphenols [32,33] that provide dark color and astringent taste [32]. In one site (Ungma), the TC was found to decrease progressively with the seasons; however, no significant relationship could be established between TC and season of the year in leaves extract of Tuli.…”

Objectives: The objective of the study was to estimate the seasonal variations in the antioxidant capacities, total polyphenol content (TPC), total flavonoid content (TFC), and tannin content (TC) of tea leaf extracts from two different plantation sites. Methods: Samples were collected from two tea gardens in Tuli and Ungma situated at N 26°39’19.3 E 094°39’22.7 and N 26°17’30.6 E 094°28’29.2, respectively, under the Mokokchung district of Nagaland, India. TPC, TFC, and TC from sample extracts were determined using Folin–Ciocalteu reagent, aluminum chloride colorimetric, and Folin–Ciocalteu assay. Apart from these, antioxidant capacities were analyzed using ferric reducing ability of plasma (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Results: The concentrations of total polyphenol, flavonoid, and tannin varied from 552.029±8.079 to 305.647±1.744 mg gallic acid equivalent/g, 238.770±0.508–148.457±1.653 mg catechin equivalent/g, and 26.453±0.485–20.173±0.173 mg tannic acid equivalent/g, respectively. FRAP and DPPH assay displayed value ranging from 2.564±0.023 to 1.074±0.023 mmol Fe(II) equivalent/g and 3.612±0.053–2.076±0.028 mmol Trolox equivalent/g. Significant seasonal variations in concentrations of these compounds were observed and a positive correlation between antioxidant capacities and phenolics of tea leaf extracts was established. Conclusion: Tea (Camellia sinensis (L.) O. Kuntze) has been regarded as a plant of immense medicinal and therapeutic value since time immemorial. The tea leaf extracts analyzed in this study gave high TPC, TFC, and TC, as well as high antioxidant activity in terms of DPPH and FRAP value. Studying such properties in tea leaves contributes more to our understandings of health benefit potentials in tea leaves and the quality of tea leaves on the basis of seasons and sites where they are planted.

“…Pemanfaatan R. simplex masih terbatas sebagai tanaman hias di Indonesia, akan tetapi beberapa penelitian telah mengungkap potensi lain dari jenis tersebut. Ekstrak etanol, etil asetat, dan n-heksana daun mahkota R. simplex mampu menghambat pertumbuhan sel kanker serviks HeLa dan R. simplex memiliki aktivitas biologi sebagai antioksidan (Tejaputri et al, 2019;Tejaputri et al, 2020). Ekstrak R. simplex menunjukkan reaksi perubahan warna apabila ditambahkan larutan asam dan basa, sehingga dapat digunakan sebagai indikator asam-basa (Mahmud et al, 2018).…”

AbstrakInformasi mengenai suku Acanthaceae di Jawa telah dianggap selesai ketika buku Flora of Java diterbitkan. Berdasarkan buku tersebut, marga Ruellia di Jawa hanya terdiri dari lima jenis, yaitu R. brevifolia, R. costata, R. elegans, R. Repens, dan R. tuberosa. Sebagian besar dari anggota Ruellia merupakan jenis asing yang ternaturalisasi, sehingga Ruellia eksotik lainnya yang belum terekam kemungkinan masih ada. Penelitian ini dilakukan untuk menyediakan informasi terkini marga Ruellia di Pulau Jawa dan akan menjadi bagian dari penulisan Alien Flora of Java. Penelitian dilakukan di Jawa Barat (Bandung, Bogor, Depok, Cianjur, Sukabumi, Sumedang, dan Tasikmalaya), Jawa Tengah (Tegal), Yogyakarta, dan Jawa Timur (Malang) pada bulan September hingga November 2020. Pengamatan spesimen Ruellia dilakukan di Herbarium Bogoriense. Penelitian ini berhasil mengungkap satu jenis tambahan spesies dari marga Ruellia, yaitu R. simplex C.Wright. Jenis tersebut dibudidayakan sebagai tanaman hias, namun populasi meliarnya telah ditemukan di Cimenyan (Kabupaten Bandung), Rancaekek (Kabupaten Bandung), Pasir Mulya (Kota Bogor), dan Leuwiliang (Kabupaten Bogor). Jenis ini diduga telah ternaturalisasi dan memiliki kemungkinan untuk tumbuh mendominasi hingga mengancam flora lokal. Secara morfologi, R. simplex dicirikan oleh perawakan yang tegak, helaian daun melanset hingga memita, dan bunga yang berwarna ungu, jambon pucat, atau putih. Kunci determinasi untuk marga Ruellia di Jawa, deskripsi jenis, foto, dan diskusi singkat disajikan dalam makalah ini.Abstract Based on the Flora of Java, the genus Ruellia in the island only consists of five species, namely R. brevifolia, R. costata, R. elegans, R. repens and R. tuberosa. Most of the species are naturalized alien flora. Thus, other exotic Ruellia that have not been recorded may still exist. Our study was conducted to provide updated information on the genus Ruellia in Java and be part of the Alien Flora of Java writing. Field study was conducted in West Java (Bandung, Bogor, Depok, Cianjur, Sukabumi, Sumedang, and Tasikmalaya), Central Java (Tegal), Jogjakarta, and East Java (Malang) from September to November 2020. Further specimen examinations were carried out in Herbarium Bogoriense and Herbarium Bandungense. This research revealed a newly recorded alien species found in Java, namely R. simplex C. Wright. The species is commonly cultivated as an ornamental plant, and it also has been naturalized in the island. Its wild populations were found in Cimenyan (Bandung Regency), Rancaekek (Bandung Regency), Pasir Mulya (Bogor City), and Leuwiliang (Bogor Regency). Ruellia simplex is characterized by its erect habit, lanceolate to linear leaves, and corolla in purple, pale pink, or white. The updated key to the Ruellia of Java, species description, photographs, and a brief discussion is presented in this paper.

“…De acordo com SAMY et al (2015), a Ruellia tuberosa tem diversas propriedades, dentre elas, anti-inflamatória, antioxidante, antibacteriana e citotóxica. Quanto a Ruellia simplex, TEJAPUTRI et al, (2019) diz que o extrato feito com acetato de etila apresentou o melhor resultado para ação antioxidante mostrando que essa espécie também tem propriedades medicinais. Desde a antiguidade, as plantas têm sido utilizadas para tratamento de diversas doenças.…”

A Ruellia simplex C. Wright, conhecida como petúnia mexicana, é comumente utilizada como planta ornamental, no entanto, estudos recentes têm relatado seu potencial medicinal. Assim, o objetivo deste trabalho foi avaliar o potencial antimicrobiano do extrato etanólico da Ruellia simplex C. Wright utilizando dois métodos de extração para obtenção dos compostos orgânicos, o estático e o ultrassom em seguida testa-los frente às cepas de Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae e Staphylococcus aureus. Foram analisadas quatro concentrações dos extratos (10 mg/mL, 15 mg/mL, 20 mg/mL, 50 mg/mL). Sendo utilizado para a avaliação da atividade antimicrobiana o método de disco difusão, onde discos de papel filtro foram embebidos nas respectivas concentrações, com quatro repetições para cada tratamento, as placas desse experimento foram incubadas a 30 °C em estufa B.O.D., onde foram observadas por 72h, e posteriormente os halos de inibição formados foram medidos e as médias obtidas foram utilizadas na análise estatística (ANOVA). O extrato estático da flor e o ultrassom da folha foram capazes de inibir o crescimento das bactérias S. aureus e E. coli, porém o extrato do ultrassom foi o mais eficaz, observando-se halos de 8 mm para S. aureus. Para a E. coli, os dois tipos de extratos obtiveram um resultado semelhante. O extrato estático da flor apresentou potencial antimicrobiano sobre S. aureus e para E. coli. Portanto, neste trabalho, foi observado que os extratos etanólicos da Ruellia simplex apresentaram atividade antimicrobiana sob as condições avaliadas. Palavras-chave: Análise antimicrobiana. Extrato etanólico. Petúnia Mexicana.
