“…The EOs of both species can be used against bacteria and fungi (Chen et al 2018;Ozogul et al 2021). They show antioxidant activities, as well as decrease the HL-60 cell viability and inhibit the cancer cells such as neuroblastomas, leukemias, prostate, and lung cancer lines (Diab 2016;Cristóbal-Luna et al 2018;Khan et al 2018). Due to all these properties, EOs of both species can be used in food, medicine, cosmetics, drugs, and pharmaceutical industries (Hardin et al 2010).…”

Grapefruit and shaddock essential oils (EOs) have remarkable biological activities. Soil types are characterized by various properties which affect the essential oils of grapefruit and shaddock. Many Citrus species are cultivated in the Nile Valley of Egypt, which is characterized by its clay soil, but there are no large areas cultivated with both grapefruit and shaddock. The reclaimed desert in Egypt which characterized by sand soil is expanded by planting many Citrus species, which produce different residues such as leaves, flowers, and peels rich in essential oil, which is used in the production of natural raw materials as a source for medicine and food. Thus, the variations of grapefruit and shaddock essential oils and their constituents were evaluated under sand and clay soils to find out the extent of the opportunities for expanding their cultivation in the new reclamation region as a natural source of EO. The leaves, flower, and peel EOs of grapefruit and shaddock were isolated by hydro-distillation and analyzed by gas chromatography and gas chromatography/mass spectrometry; data were statistically analyzed by one-way analysis of variance. Samples collected from trees grown in sand soil produced the greatest amounts of essential oil in both species whatever the organ from which this oil was extracted. Limonene was of the major compound in both peel and flower grapefruit essential oils, while sabinene was the predominant one in leaves EO (39.8% and 44.8%, in clay and sand soils respectively). E-phytol, linalool, and limonene were the predominant constituent in leaves, flower, and peel of shaddock essential oil, respectively. Various identified constituents in leaves, flowers, and peels noteworthy the presence of oxygenated diterpenes in percentage not less than 33% in leaves shaddock essential oil which was completely omitted in the other organs and in the grapefruit EOs. The monoterpene hydrocarbon was the major chemical class in various essential oils of grapefruit; oxygenated diterpenes, oxygenated monoterpenes, and monoterpene hydrocarbon were the main chemical classes of leaves, flower, and peel essential oils from shaddock, respectively. In the essential oil contents (%), most of the main constituents and major chemical groups were higher under sand soil than clay soil. This study serves as a reference for selection the suitable soil to produce the essential oil according to the components of interest; also, this trial recommends the cultivation of both species in reclaimed sand soil of Egypt.

“…Pomelo peel extract coated rice straw paper (6 mm in diameter) showed a better bactericidal effect against S. aureus than E. coli (Chollakup et al, 2020). However, PFE in the study of Hasan Khan (2018) was not found to induce the inhibitory activity against tested bacteria which could possibly be ascribed to the pomelo variety or maturity stage. Besides, S. typhimurium, and P. aeruginosa were found to be highly susceptible to the treatment that was in agreement with previous reports (Aydeniz Güneşer et al, 2018; Tawfik, Al‐Haliem, & Al‐Ani, 2010; Van Hung, Yen Nhi, Ting, Lan Phi, & Al Loman, 2020).…”

The pomelo flavedo extract (PFE) from the pomelo peel (an agricultural waste) is well known with many functional properties. In this study, the incorporation of PFE into the bio-based polymer (pectin) for the formulation of the coating film was generally developed. The PFE showed a very high inhibitory effect against Pseudomonas aeruginosa (9.22 ± 0.37 mm of inhibition zone diameter), whereas Escherichia coli was found to be resistant to the PFE treatment. The incorporation of varying PFE contents into the pectin film with glycerol as a plasticizer for developing PFE-Gly-Pectin composite film and its effect on the film performance was investigated. PFE was found to reduce the swelling degree and increase the solubility of the Gly-Pectin film as well as increase the flexibility of the resulting film. However, the molecular structure, structural morphology, and contact angle of the Gly-Pectin film were insignificantly affected by the presence of PFE. The composite film at the PFE:Pectin ratio of 3.4 g/g was selected for the preliminary preservation of jackfruit bulbs which was stored at ambient temperature. As a result, coated jackfruit bulbs appeared to maintain a better quality after 3 days with an alleviated change in weight loss, color parameters, and total soluble solids, whereas the uncoated jackfruits showed signs of spoilage on Day 2 of the storage period. Therefore, the PFE conjugated pectin film suggested potential in the preservation of food materials.

“…DPPH (2,2-diphenyl-1-picrylhydrazyl) assay used to evaluate the antioxidant activity of the extract prepared in nhexane extract by measuring the scavenging capacity of DPPH present in the tested solvent extract. Khan et al (2018) represented that the DPPH scavenging assay was an antioxidant method conducted commonly due to their highly selectivity compared to other antioxidant test.…”

Abstract. Kalsum U, Susanto S, Junaedi A, Khumaida N, Purnawawati H. 2021. Flowering and fruit quality characteristics in some seeded and seedless pummelo cultivars. Biodiversitas 22: 379-386. Most of the pummelo cultivars with seeds, while other parts of it are seedless. Each cultivar is thought to have his characteristics. This study aimed to obtain more detailed information related to the difference in flowering characteristics and fruit quality of seeded and seedless pummelo cultivars. This experiment used a randomized block design with four treatments, i.e., seeded pummelo (Adas Duku and Bali Merah 1) and seedless pummelo (Bali Merah 2 and Jawa 1). The results showed an irregular pattern in the flowering and harvesting period in both the seeded and seedless groups. Adas Duku blooms twice whereas Bali Merah 1 and the two cultivars of the seedless group bloom only once a year. The highest total flower number from the four cultivars was Adas Duku and followed by Jawa 1>Bali Merah 1>Bali Merah 2. Seeded pummelo was not significant difference with seedless pummelo on several variables, except the total titrable acidity (TTA) content (seeded group > seedless group). Adas Duku became the best cultivar compared to the other three cultivars in several characteristics, such as the lowest peel thickness, the highest in the edible portion, the total soluble solids (TSS) and TTA of flesh fruit.
