Abstract

The leaves of sea hibiscus (Hibiscus tiliaceus L.) are known to have good antibacterial activity against Escherichia coli and Staphylococcus aureus, which is associated with the saponin, flavonoid, polyphenol, and tannin contents. Chemical compounds in plant extracts are, however, influenced by the extraction method used. This study aimed to determine the antibacterial activity of the ethanol extracts of Hibiscus tiliaceus L. leaves obtained using four different extraction methods against E. coli and S. aureus. In the maceration, percolation, reflux, or Soxhlet method, 200 g of the crude drug (i.e., dried sea hibiscus leaf powder) was extracted with 96% ethanol, and the derived extract was tested at 1%, 2%, 3%, 4%, and 5% concentrations. The disk diffusion method was used to test the antibacterial activity by observing and statistically analyzing the diameter of the zones of inhibition. Results showed that all the ethanol extracts have antibacterial properties against E. coli and S. aureus,with the maceration-produced extract forming significantly different zones of inhibition from the other methods (percolation, reflux, and the Soxhlet) at all concentrations.

Abstract

The prevalence of breast cancer cases in Indonesia is increasing along with the ability of cancer cells to migrate or move from the primary tumor mass and form new colonies elsewhere. The migration of cancer cells has encouraged the develop anticancer drugs from natural ingredients. Waru leaves have been shown to have cytotoxic activity. This study aims to determine the inhibition activity of migration of breast cancer cells 4T1 from methanol extract of waru leaves. Waru leaves methanol extract was obtained using the maceration method. Cytotoxic test of methanol extract of waru leaves (MEWL) was the migration test used in the scratch wound healing method at concentrations 162.5, 325, and 650 μg/mL at 0, 18, 24, and 42 hours after treatment. Analysis of IC50 using linear regression, while large areas were analyzed using Image-J software. The percentage of data closure was analyzed statistically with the Anova Repeated Measure test. All concentrations of Methanol Extract of Waru Leaves had significant inhibition of cell migration (p<0,05) compared to control at each observation time at 0, 18, 24, and 42 hours after treatment.

Abstract

Breast cancer is a cancer that ranks the highest incidence in Indonesia. One of the plants that can be used for this treatment is a bay leaf (Eugenia polyantha Wight). Purification techniques can optimize the extraction of flavonoid compounds to create larger concentrations of these substances. Old bay leaves' ethyl acetate fraction has lethal effects on T47D cancer cells. In this work, the amounts of flavonoids and the cytotoxic activity of young bay leaves' pure extract and ethyl acetate fraction against T47D cells are to be determined. By using the maceration process, two phases of methanol extraction from young bay leaves were produced. In the first stage, ethyl acetate was used to partially purify the material, and in the second stage, n-hexane, ethyl acetate, and water. Cytotoxic tests of purified extract and ethyl acetate fraction of young bay leaves were carried out at 200; 350; 500; 750; and 1000 µg/mL. Cytotoxicity test using the MTT assay method. IC50 value analysis using linear regression. Determination of total flavonoid content using a UV-Visible spectrophotometer with a comparator compound, quercetin. The results showed that the purified extract of young bay leaves and the ethyl acetate fraction of methanol extract of young bay leaves had cytotoxic activity with IC50 values of 570.57 ± 30.72 µg/mL and  588.45 ± 6.90 µg/mL, respectively. Total flavonoid levels were 9.80 ± 0.05 mgQE/g and 5.99 ± 0.06 mgQE/g.The purified extract and ethyl acetate fraction on young bay leaf extract (Eugenia polyantha Wight) had cytotoxic activity on T47D cells and the highest levels of flavonoids in the purified extract.

Abstract

The most common type of cancer in Indonesia is breast cancer. Anticancer medications made of natural ingredients are beginning to be produced. Methanol extract of young bay leaves (Eugenia polyantha) has anticancer activity at moderate levels. The compounds that function as anticancer are flavonoids. The duration and extraction technique can have an impact on how active chemicals are extracted from natural materials. Through variations in the duration of the extraction process for young bay leaves, this study seeks to ascertain the amounts of flavonoids and the cytotoxic activity of T47D breast cancer.Young bay leaf ethanol extract (EEDSM) was obtained using the Ultrasonic assisted extraction (UAE) method with 70% ethanol solvent and varying extraction times of 5, 15, and 25 minutes. EEDSM total flavonoid content was tested using the UV-visible spectrophotometric method with quercetin as a comparison. The cytotoxic test of the ethanol extract of young bay leaves was carried out using the MTT assay method. Determining the IC50 value uses linear regression and probit analysis. It will also use One Way ANOVA to quantitatively determine the significance of the difference between the effect of extraction time and the IC50 value on T47D breast cancer cells. The results showed that EEDSM with extraction times of 5, 15, and 25 minutes had total flavonoid levels of 2.13mgQE/g, 2.36mgQE/g, and 2.61mgQE/g and cytotoxic activity with an IC50 value of 843μg/mL; 1007μg/mL; and 735μg/mL. EEDSM 5 and 25 minutes were shown to have moderate levels of cytotoxic activity.

Abstract

Post-harvest management is essential because it will affect the final results. Post-harvest management products can be classified as simplicia because the stages include wet sorting, washing, draining, changing shape, drying, packaging, and storage. These steps must be paid attention to to ensure the content of active compounds in simplicia. The Bejo Bintang Toedjoe herbal garden at the Plalangan Gunungpati sub-district is managed by women from the Plalangan sub-district, both housewives and workers. Community service was implemented by preparing and making leaflets/brochures, conducting site surveys, conducting pretests and posttests, and monitoring and evaluating the practical results. This activity was attended by 25 participants, not only participants from the managers of the Bejo Bintang Toedjoe herbal garden but also residents from representatives of several community associations. The discussion session was opened after the counseling had been delivered. After the discussion session is finished, it continues with practice. The results of the pretest analysis showed that most participants still need to learn the effect of direct heating with sunlight for drying medicinal plant materials. Some participants also needed to learn that the tools used to cut medicinal plant materials were stainless steel. The posttest results showed that there was an increase in knowledge after conducting counseling and post-harvest management practices of medicinal plants.

Abstract

Dengue fever (DF) is a global health problem. The epidemiology of dengue fever in Indonesia varies but continues to increase. Dengue fever itself is caused by the Aedes aegypti (Linn.) mosquito. Indonesia's tropical geographical location provides conditions that support the breeding of disease-carrying mosquitoes. This demonstrates the urgency with which disease-carrying mosquito eradication must be carried out. Currently, mosquito control strategies rely on the use of chemical drugs to control mosquitoes, which often cause side effects. Therefore, many mosquito repellents have been developed based on natural ingredients. Cymbopogon nardus, the plant that yields citronella essential oil, is one of them. The purpose of this PkM project is to increase knowledge regarding the benefits of citronella oil. In addition, it also improves the skills of participants to produce citronella oil as an anti-repellent. This training method is a combination of lectures, demonstrations, and practical actions. Participants will be given counseling regarding the benefits of citronella oil for health. The making of roll-on preparations begins with watching tutorials and live demonstrations by the team which are then followed by the participants. The results of this activity showed an increase in participants' knowledge and skills in making lemongrass aromatherapy roll-on preparations. This can be seen in the PkM product in the form of a roll-on aromatherapy preparation that has a distinctive lemongrass aroma, warm and stable at room temperature. Participants can also plan to make roll-on preparations using other essential oils. The knowledge gained is expected to be developed by participants as entrepreneurial capital. The community service activities were carried out smoothly and according to target. The PkM team succeeded in increasing the knowledge and skills of the participants through PkM activities.
