Abstract

Piper porphyrophyllum or known as tiger’s betel, is a medicinal plant of the Piper genus that is quite widespread in Indonesia, especially on Java, Sumatra, and Kalimantan island. Tiger’s betel is widely used traditionally to treat headaches, bone pain, chest tightness, skin diseases, relieve inflammation, and diabetes mellitus. This study aims to determine the type of secondary metabolite compounds contained in the ethyl acetate fraction of tiger’s betel and determine its antidiabetic activity. Determination of the type of compound is conducted by phytochemical screening by a qualitative test using various reagents to identify flavonoids, phenolics, saponins, triterpenoids, steroids, alkaloids, and coumarins. The antidiabetic assay was carried out by inhibiting α-glucosidase activity and the results were reported as IC50 values. The ethyl acetate fraction of tiger’s betel positively contains alkaloids, flavonoids, and phenolics. The antidiabetic activity is classified as very strong, with an IC50 value of 14.06 µg/mL.

Abstract

The marine sponge Aaptos suberitoides has been shown to have anticancer properties, with clear evidence of its capacity to suppress the growth of cancer cells. However, the pharmaceutical exploration of chemicals from marine organisms causes significant environmental concerns. Aspergillus unguis, a fungal symbiont of the marine sponge A. suberitoides, has been isolated for its potential in sustainable natural products resources. This study assesses the antioxidant activity of ethanol extract and the toxicity of four levels fractions from ethanol extracts of A. unguis mycelium and these results were reported for the first time in this study. The antioxidant of ethanol extract was determined using the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) method. The fractions were examined for toxicity using the Brine Shrimp Lethality Test (BSLT). The ethanol extract of A. unguis shows very strong antioxidant bioactivity (IC50 = 42.84 mg/L). The LC50 values for hexane, chloroform, ethyl acetate, and butanol fractions were determined to be 74.11 µg/mL, 93.84 µg/mL, 59.37 µg/mL, and 142.79 µg/mL, respectively. It indicates significant toxicity. These preliminary results are important knowledge for further research into the bioactivity potential of the metabolites as candidate anticancer compounds, aligning with marine pharmaceutical drug development.

Abstract

The Moringa plant, a tropical species, exhibits prolific growth and is abundantly present in Indonesia and other tropical regions worldwide. An extended lifespan, continuous flowering, and a high tolerance for elevated temperatures characterize it. Utilizing its components, including leaves, bark, seeds, and roots, this multifaceted plant is renowned for its therapeutic properties. The plant's antioxidants and various nutrients, including vitamins and minerals (iron, magnesium, vitamin B6, vitamin B2, vitamin C, and vitamin A), have led to studies on the plant's potential health benefits. In order to develop the local economy in Ulakan village, Padang Pariaman Regency, Moringa plants were processed by using the plant leaves to manufacture herbal tea, which can then be sold. This community service program was significant given the widespread presence and ease of cultivation of Moringa plants within the local region. The program involved the planning and selection of the activity site, the implementation of training sessions, and the assessment of the program's outcomes. The result of this community engagement initiative was the demonstrated interest of many participants in producing Moringa leaf tea.

Abstract

The abundance of natural medicines in nature is very capable of being used and developed in various lives both individually and in combination in the modern medical field. Various developments and treatments as well as the discovery of new concepts will be able to interact with human physiology. One plant that has the potential to be developed is Melastoma malabathricum, also known as senduduk. This plant from the Melastomataceae family is easily found in tropical Asia and has long been used as an herb in traditional Chinese medicine. Based on the data collected, various studies have shown the pharmacological bioactivity of Melastoma malabathricum which has antibacterial potential and is able to fight resistant bacteria. Chemicals in this plant, including flavonoids, terpenoids, alkaloids, and steroids have been detected and shown to be inhibitors of bacterial growth, including resistant bacteria.

Abstract

Cymbopogon nardus L. Rendle is one of the world trades essential oil plants. The high selling value of citronella oil is determined by the characteristics of its physical and chemical properties. In this study, determined the physical and chemical properties of citronellal oil isolated by two different methods, namely method of laboratory distillation (M1) and local community distillation (M2). The result showed that the essential oil produce from both methods match with SNI 06-3953-1995 on its physical properties. The results of the chemical composition using Gas Chromatography-Mass Spectrometry (GC-MS) indicated there are 38 and 48 compounds in the essential oil of M1 and M2, respectively with the main compositions are citronellal, citronellol, and geraniol. The antibacterial activity evaluated using the disc diffusion method showed inhibitory ability against the growth of Staphylococcus aureus and Staphylococcus epidermidis, but no inhibitory ability of Pseudomonas aeruginosa. Both, these M1 and M2 essential oils are categorized as a very strong antibacterial at concentration of 3.125% and 50%, respectively.

Abstract

Piper aduncum L., commonly known as spiked pepper, is a medicinal plant traditionally used to treat various diseases due to its diverse, active compounds. This article investigates the chemical composition, cytotoxic bioactivity in vitro and the silico of the essential oil (EO) from the flowers of Piper aduncum collected in Padang City, Indonesia. The EO was obtained by hydrodistillation using a Clevenger-type apparatus and characterized by gas chromatography-mass spectrometry (GC-MS). The in vitro cytotoxicity of the EO was assessed against cervical cancer (HeLa cancer cell line) using the MTT assay and further explored through molecular docking approaches. The main constituent of the essential oil from the flowers was dillapiol (31.68%). The LC50 and IC50 values were 31.3471 µg/mL and 65.83 µg/mL, respectively. Computational screening was performed to observe the interactions between active compounds and proteins AKT and ERK2 using molecular docking. AKT and ERK2 act as critical regulators in the PI3K/Akt and ERK/MEK signaling pathways and are potential drug targets for cancer therapy. The compounds used complied with ADMET analysis and toxicity profile. However, it is noteworthy that there have been no previous reports on the essential oil from Piper aduncum flowers from Padang City specifically targeting cervical cancer, which molecular docking studies have complemented. The results suggest that the essential oil from the flowers of Piper aduncum can be further studied as a potential lead in drug discovery for cervical cancer.

Abstract

The red betel plant (Piper porphyrophyllum) belongs to the Piperaceae family which is traditionally used to treat various diseases, including headaches, bone pain, chest tightness, leprosy, stomach ache, as well as for various other diseases such as skin diseases and diabetes. In this study, the antibacterial activity was tested for the hexane, ethyl acetate and methanol extracts of red betel nut using the disc diffusion method and the isolation of secondary metabolites from the hexane fraction of red betel nut using column chromatography technique. Determination of the antibacterial activity of the three fractions showed that the methanol extract had better antibacterial activity compared to the hexane extract and ethyl acetate extract. UV spectrum analysis showed 3 bands with absorption of 282 nm in band I, 274.80 nm in band II and 224.80 nm in band III which means that they show characteristics for triterpenoid group compounds. FTIR analysis showed the presence of C-H, CH2, C=O, C-O alcohol and geminal dimethyl functional groups in the isolated compounds.
