Myristica fragrans Houtt (nutmeg) is used as a spice and flavour for food and beverages. It has been traditionally used to treat a number of medical conditions, including diabetes mellitus. The study was undertaken to scientifically validate the traditional use of mace from M. Fragrans. The objectives of this study were to evaluate α-glucosidase inhibition, antioxidant and antibacterial activities of water extract (WE) and essential oil (EO) from M. fragrans mace. Both WE and EO were evaluated for their α-glucosidase inhibitory activities in vitro and their antioxidant activities based on DPPH radical scavenging assay. Standard compounds were used for every test. Total phenolic and flavonoid contents of both extracts were also determined. The extracts were also tested for their antibacterial activities against six different bacteria by a well diffusion method. Both extracts showed inhibition activities against α-glucosidase, with WE showed stronger activity than EO (IC50 = 1.86 and 8.15 mg/ml). Good radical scavenging activities were observed for both extracts, with WE showed stronger activity than EO (IC50 = 1.51 and 4.59 mg/ml). WE showed higher content in phenolic than EO (47.84 and 37.21 mg GAE/100 g DW). Flavonoid content in WE was also higher than EO (215.36 and 30.12 mg RE/ml). Based on the well diffusion method, only EO exhibited antibacterial activities, with inhibition zone in the range 1.03 – 1.30 mm. The strongest activity was observed against Staphylococcus mutans. The results indicate WE and EO can be exploited further for pharmacological uses, in particular for their antidiabetic and antioxidant activities.

Pinus Merkusii

The most common human pathogen that colonizes in a third of healthy people around the world are Staphylococcus aureus, and one of the materials allegedly able to overcome the pathogen is resin. Resin has been used in folk medicine for thousands of years to treat diseases. The antimicrobial activity of natural resins can be associated with a variety of organic compounds contained in them such as diterpenoids and triterpenoids. This research aimed to explore the antibacterial and antioxidant activities of Pinus merkusii, P. oocarpa, P. insularis, Agathis loranthifolia resins and essential oil. Resin was separated by distillation process to get essential oil and the residue was extracted using n-hexane, ethyl acetate (EtOAc), and methanol (MeOH). Antioxidant activity was performed by DPPH (1,1diphenyl-2-picryl hydrazyl) radical scavenging method. The antibacterial activity of resins and essential oil of the samples determined using the disc diffusion method against Staphylococcus aureus and Escherichia coli. The results showed that the yield of resin extract was ranging from 8.44 % to 95.56%. All extracts and essential oil could not inhibit E coli growth but inhibit the S. aureus growth. This experiment concluded that resin n-hexane extract from P.oocarpa was the most potent as antibacterial activity against S. aureus. All of the samples used had less potential antioxidant activity compared to positive control ascorbic acid. Result of this study show that pine resin from Indonesia has potential as an antibacterial agent.

Abstract Satureja rechingeri is a rare endemic and endangered species found in Iran. Its propagation, variations in essential oil and phenolic content, as well as antioxidant and antimicrobial activities at different phenological stages are reported in this study. The chemical composition of essential oils obtained by hydro-distillation from the aerial parts were determined by GC and GC-MS. A total of 47 compounds were identified in the essential oils of S. rechingeri at different phenological stages. The major components of all oils were carvacrol (83.6%–90.4%), p-cymene (0.8%–2.9%) and γ-terpinene (0.6%–2.4%). The total phenolic content and the antioxidant activity of methanolic extracts were determined with the Folin-Ciocalteau reagent and by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging and ferric reducing antioxidant power (FRAP) assay, respectively. Total phenols varied from 35.5 to 37.5 mg gallic acid equivalents/g dry weight (dw), and IC50 values in the radical scavenging assay ranged from 46.2 to 50.2 mg/mL, while those in the FRAP assay were between 49.6 and 52.5 μM quercetin equivalents/g dw. By the disc diffusion method and by determination of the minimum inhibitory concentrations (MIC), the essentials oils of the various phenological stages were found to have high activities against four medically important pathogens.
