“…The magnesium contents of different Nigerian spices including Cameroon pepper (124.6 mg/g), nutmeg (260.7 mg/g), clove (201.2 mg/g), ginger (176.4 mg/g), and turmeric (136.4 mg/g) reported by [22] are slightly in agreement with the values obtained for samples in this study. The magnesium contents of African nutmeg (182.99 mg/g) reported by [52] and other Cameroon spice (132 mg/g) by [53] are in agreement with the values observed for samples in this study. The findings of [37] on magnesium content of garlic (4.10 mg/g), ginger (5.00 mg/g) and pepper (4.50 mg/g) are lower than the values obtained for samples in this study.…”

“…There was no significant difference (p≥0.05) between cloves powder (CP) and ginger powder (GP) while other samples differed significantly (p≤0.05) from other samples. The iron contents of samples in this study are lower than the values reported by [52] and [54] for iron contents of African nutmeg (90.00 mg/g) and Byrsocarpus dinklage (efu) (598.00 mg/g). Ekeanyanwu et al [55] also reported (21.71 mg/g) for iron contents of African Nutmeg which are higher than the values obtained for samples in this study.…”

This study investigated the production and quality evaluation of selected spices [Ginger (Zingiber officinale), garlic (Allium sativum), turmeric (Curcuma longa) and clove (Syzygium aromaticum)]. The spices were labeled GP (garlic powder), TP (turmeric powder), CP (cloves powder) and GPW (ginger powder). The samples were evaluated for phytochemicals, β-carotene and minerals using standard procedures. The selected phytochemicals ranged as follows: (24.09 – 986.68 mg/g), phenol (150.85 – 2027.00 mg/g), flavonoids (32.55 – 2186.91 mg/g) and alkaloids (4.49 – 6.16 mg/g). The β-carotene content of samples ranged from 0.04 to 3.50 mg/g. For the selected mineral composition of samples, the results indicated; calcium ranged from 81.16 to 120.43 mg/g, potassium ranged from 129.35 to 815.28 mg/g, magnesium ranged from 10.59 to 160.80 mg/g, iron ranged from 1.01 to 14.86 mg/g and phosphorus ranged from 40.26 to 209.99 mg/g. The cloves powder (CP) had the highest level of tannin and phenol while turmeric powder had the highest β-carotene. Mineral content showed that potassium and calcium was more in ginger than other samples while others were high in turmeric powder.

“…In addition to containing active compounds, M. fragrans filtrate is also known to contain various vitamins and minerals. M. fragrans, especially the seeds, contain high levels of Mn, Mg, Na, Fe, Cr, Ca, and K. In addition, M. fragrans seeds were also reported to contain high amounts of vitamins such as Vitamin B1 5.63%, Vitamin C 9.88%, vitamin E 5.50% and other vitamins in smaller amounts (Nkwocha et al 2019). Vitamins and minerals are ones of the important growth factors that allow good growth of endophytic bacteria and in turn also affect the total population.…”

Abstract. Yunita M, Ohiwal M, Dirks CS, Angkejaya OW, Ilsan NA, Sukmawati S. 2022. Endophytic bacteria associated with Myristica fragrans Houtt: Improved media, bacterial population, preliminary characterization, and potential as antibacterials. Biodiversitas 23: 4047-4054. We have investigated a similar study previously and only obtained 4 isolates that were able to inhibit pathogenic bacteria with a very small inhibition index (1.5 mm-3.4 mm) in NA media. Therefore, the current study was conducted by improving the NA media with the addition of 1% peptone and Myristica fragrans filtrate. The study aimed to evaluate the potential of endophytic bacteria as antibacterials in the modified NA media. Endophytic bacteria were isolated from 5 organs of M. fragrans and were grown on Nutrient Agar added with 1% peptone and M. fragrans filtrate. The total bacterial population was analyzed by the TPC method. Preliminary characterization consisted of macroscopic and microscopic observations. Antibacterial test was carried out by agar diffusion method. The total population of endophytic bacteria varied for all organs of M. fragrans, with the highest population was found in the seeds (1x105 CFU/gr), while the least was found in the pulp (9x103 CFU/gr). A total of 10 isolates were selected and preliminary characterization showed that endophytic bacteria had different macroscopic and microscopic characteristics. All isolates were able to inhibit the growth of Escherichia coli ATCC-27853 and Staphylococcus aureus ATCC-29213 with the largest inhibition zone index was obtained by isolate BJ1 (22.5 mm and 23.8 mm), while the smallest was obtained by isolate TD2 (12.5 mm and 13.6 mm) which were still categorized as strong inhibition. The study concluded that the addition of 1% peptone and M. fragrans filtrate in NA media was able to show far better results compared to our previous study and the strong antibacterials can be developed and formulated in the future.

“…Also, nutmeg is used in the manufacture of many cosmetic products such as creams, soaps, shampoos, perfumes, etc [8]. Historically, nutmeg was a key ingredient in medical preparations that were recommended to treat stomachaches, diarrhoea, mouth sores, joint pains, insomnia, lowering blood pressure, and dissolving kidney stones [2][9] [10].…”

The present study was conducted with the aim to extract phytochemical constituents of nutmeg (Myristica fragrans) seeds using methanol and acetone solvents, respectively by soxhlet apparatus with a yield of (1.47gm/100 gm) for methanol solvent and (2.11gm/100gm) for acetone solvent. The two extracts were tested for their antimicrobial, antioxidant and antiinflammatory activities. Agar well diffusion method was adopted against four bacterial species including two Gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis) and two Gram-negative bacteria (Escherichia coli, and Klebsiella sp.) as well as one yeast (Candida albicans) to determine the antimicrobial activity. The present study showed that the tested microorganisms were inhibited by nutmeg acetone extract with an inhibition zone ranging between (11-15 mm), especially toward Candida albicans with 15 mm diameter while no inhibition zone was observed using methanol extract. Chemical constituents of nutmeg acetone extract were estimated using Atomic Absorption Spectrometry (AAS) and Gas Chromatography-Mass Spectroscopy (GC-MS) measurements revealed the presence of 150 µg/dl Cu, 280 µg/dl Zn, 6.1 µg/dl Pb, 0.08 µg/dl Cd, 0.09 µg/dl Cr, 0.0012 µg/dl Ni and 0.027 µg/dl Mn and 32 extra compounds. Other phytochemical detections including alkaloids, tannins, terpenoid, saponins, glycosides, resins, and flavonoids were investigated using standard procedures. Total phenol content and radical scavenging activity were measured quantitatively using Folin-Ciocalteu and 2,2-diphenylpicrylhydrazyl (DPPH) methods, respectively and were compared qualitatively with the microfluidic paperbased analytical device (µPADs) as a new platform. The extract contains a high concentration of phenolic compounds (0.6217 mg/ml) and the DPPH assay for acetone extract indicated a high amount of antioxidant compounds. The effect of nutmeg acetone extract on cyclooxygenase (COX-2) enzyme activity has been done and showed that the nutmeg extract can inhibit COX-2 activity better than the ability of anti-inflammatory drug (Aspirin). Our findings indicate the potential use of nutmeg acetone extract as a source of antimicrobial, antioxidant, and anti-inflammatory agent.
