Abstract

Knobweed (Hyptis capitata) is a member of the genus Hyptis and the medicinal properties remain underexplored in scientific research. In this context, the use of Hyptis capitata essential oil as a medicinal plant depends on phytochemical content. Hyptis capitata is easily found in rice fields or agricultural areas such as Banyuwangi. Therefore, this research aimed to describe phytochemical compounds, antioxidants, and antibacterial activity of essential oil Hyptis capitata in Banyuwangi using Solvent-Free Microwave Extraction (SFME) method. Essential oil from leaves and inflorescence of the species was obtained with a yield of 0.273% and 0.282%, respectively. The results of Gas Chromatography-Mass Spectrometry (GC-MS) analysis showed that inflorescence and leaves of Hyptis capitata consisted of diterpenes, triterpenes, sesquiterpenes, esters, alcohols, ketones, and other groups of compounds. SFME method for the extraction affected both essential oil yield and phytochemical composition. Meanwhile, there were variations in phytochemical compounds of the plant parts used and from several previous research. The optimum % DPPH inhibition value of leaves extract and inflorescence were 19.187±0,06% and 18.784±0,06%, respectively. Antibacterial activity against Staphylococcus aureus and Eschericia coli reported no inhibition of plant extract. Phytochemical analysis showed several compounds with antibacterial potential, suggesting the need for further research of antibacterial activity against other pathogenic bacteria and exploration of additional biological activities.

Abstract

Holy basil (Ocimum tenuiflorum, L.) is one of the aromatic herbs that grows in empty or abandoned areas. Previous studies used conventional methods, including maceration and hydrodistillation, to extract Ocimum tenuiflorum, L. Genetic variation, plant phenology, geographical conditions, and extraction techniques affect the yield and variability of essential oil phytochemical composition. Here in, we report essential oil extraction of Ocimum tenuiflorum green and purple using solvent-free microwave extraction. The yield calculation obtained from purple and green O. tenuiflorum essential oils was 2.25 and 2.17%, respectively. GCMS data shows that the phytochemical compounds in Ocimum tenuiflorum essential oils, purple and green leaves, are dominated by sesquiterpene and phenylpropene groups. In the essential oil of purple Ocimum tenuiflorum leaves, the major phytochemical compound components are methyl eugenol, β-Caryophyllene, and Germacrene-D.  Antibacterial activity showed that Ocimum tenuiflorum purple essential oils a more preeminent effect against Escherichia coli than green.

Abstract

Di akhir tahun 2019, Dunia digemparkan dengan adanya Coronavirus Disease 2019 (Covid-19). Hingga saat ini Covid-19 telah menjadi masalah dunia internasional dan memberikan implikasi terhadap ekonomi, sosial, dan politik hampir diseluruh negara, termasuk di Indonesia. Di Indonesia sendiri dampak ekonomi akibat pandemi Covid-19 juga dirasakan sektor UMKM. Salah satu UMKM yang terkena dampak pandemi adalah UMKM penjual makanan di Desa Lesanpuro, Kecamatan Kedungkandang, Malang yang selama pandemi mengalami penurunan penjualan dan pendapatan. Untuk meningkatkan penjualan dan pendapatan, kami membantu dengan memberikan sosialisasi, edukasi dan pendampingan pengembangan inovasi produk dan pemanfaatan media digital untuk pemasaran produk. Pada tahap pertama kami melakukan sosialisasi yang bertujuan untuk mengembangkan area pemasaran dengan mengenalkan digital marketing kepada pemilik UMKM supaya digital marketing tersebut dapat digunakan sebagai sarana untuk memasarkan produk yang lebih luas jangkauannya sehingga diharapkan bisa mendapatkan penghasilan yang lebih banyak. Pada tahapan yang terakhir kami juga mengedukasi tentang pentingnya menciptakan inovasi produk kreatif agar UMKM tersebut memiliki ciri khas yang dapat dengan mudah dikenal konsumen sehingga dapat menarik minat konsumen. Tahap terakhir kami melakukan pendampingan inovasi produk baik dari segi isi produk, nama produk, kemasan, dan logo usaha.  Diharapkan dengan adanya kegiatan  ini dapat membantu UMKM tersebut agar bisa meningkatkan pendapatannya dan bisa bertahan di tengah pandemi Covid-19.
Solvent-Free Microwave Extraction: Phytochemistry and Bioactivities of Essential Oil from Stachytarpheta jamaicensis, L. in Banyuwangi Susanti, Yuni; Pambudi, Setyo; A'yun, Ayu Qurota; Aprilia, Melinda; Hanum, Nabila Salsabila; Armadan, Dwi Danang

Abstract

ABSTRACT. Stachytarpheta jamaicensis, L. is a member of the Verbenaceae family. It is a medicinal plant easily found on vacant land and in rice fields in Banyuwangi. The present study is the first detail reported to examine the phytochemical compound and bioactivities of essential oil from S. jamaicensis L., using solvent-free microwave extraction (SFME). Forty chemical compounds were identified in the inflorescence and thirty in the leaves. β-caryophyllene, fulvoipolamiide, hexahydrofarnesyl acetone, t-phytol, neophytadiene, and squalene were identified in inflorescence oil. In contrast to the inflorescence, where these compounds were present in minor amounts, fulvoipolamiide, t-phytol, and squalene were the predominant components in the leaf oil. The IC50 values of leaves and inflorescence essential oils were 30.566 mg/mL and 52.510 mg/mL, respectively. Based on IC50 values, leaf essential oils have stronger antioxidant potential than inflorescence. Antibacterial and antifungal tests indicated that the leaf essential oil possesses greater antimicrobial efficacy than that of the inflorescence. These findings suggest that the essential oil of S. jamaicensis is a promising source of antioxidant, antibacterial, and antifungal agents, and holds potential for future pharmaceutical applications.
