“…In postharvest processing, the fruit pulp is mostly used, while the peel and seeds are considered to be discarded by-products. It has been reported that custard apple peel contains many phenolic compounds, mostly alkaloids, flavonoids, and terpenoids, with antibacterial and antioxidant characteristics (Nguyen et al, 2021;Sidhu and Zafar, 2020). Therefore, the combination of this custard apple peel extract with chitosan coating can be highly potential for shrimp preservation as well.…”

This study examined the changes in the quality of the Pacific white shrimps coated with chitosan incorporated with custard apple peel extract (ASE). Generally, there was a positive effect on texture, color, and biochemical characteristics of shrimp samples treated with either chitosan coating or chitosan coating combined with ASE as against the control after 12 days of storage at 4°C. The increases in the values of weight loss, pH, peroxide values, total volatile basic nitrogen, and thiobarbituric acid reactive substances of shrimps were significantly inhibited in shrimps treated with a chitosan-ASE coating. Coating with chitosan combined with ASE at a concentration of 300 mg GAE/L was proven as the most effective preservation method for whiteleg shrimp during cold storage. Thereby, it may suggest that the combination of chitosan and ASE could be used as an effective alternative for the natural coating to extend the shelf-life and maintain the shrimp quality.

“…(Malvaceae) is a deciduous, fast-growing tropical shrub or small tree that usually grows on marginal soils (Boon and Pooley 2010). Species of this genus have been known to have numerous medicinal properties (Goyal 2012;Ullah et al 2012;Sidhu andZafar 2020) i.e., antibacterial, antimalarial, antifertility, antifungal, antioxidant, antiviral, antidiabetic, antipyretic, anti-inflammatory, anthelmintic, radioprotective, analgesic andhepatoprotective (Zia-Ul-Haq et al 2012;Sinha et al 2015;Shukla et al 2016;Dwivedi and Manigauha 2017;Oribayo et al 2018;Pramodini et al 2018). However, G. lasiocarpa has been reported to have medicinal and nutritive properties (Akwu et al 2019a, b, c).…”

Abstract. Akwu N, Naidoo Y, Singh M, Thimmegowda SC, Nundkumar N, Lin J. 2020. Isolation of lupeol from Grewia lasiocarpa stem bark: Antibacterial, antioxidant, and cytotoxicity activities. Biodiversitas 21: 5684-5691. Lupeol a pentacyclic triterpenoid, was extracted from the stem bark of Grewia lasiocarpa. Stem bark was macerated with chloroform (CHCl3) at 25 ± 2°C, and then purified using a silica gel column. The mobile phase was hexane (100%) and hexane: ethyl acetate (80:20) as the mobile phase. The structure of lupeol was identified by 1HNMR, and 13C NMR spectral data, compared with reported data. The antibacterial, antioxidant and cytotoxicity activities of lupeol were evaluated using agar-well diffusion against six clinic bacteria isolates, namely Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853), Klebsiella pneumoniae (ATCC 314588), and Salmonella typhimurium (ATCC 14026) Gram-positive bacteria: Staphylococcus aureus (ATCC 25923), methicillin-resistant Staphylococcus aureus (MRSA) (ATCC BAA-1683). The antioxidants assays were performed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP). Cytotoxicity activity was carried out by MTT (3-(4,5-dimethylthiazol)-2,5-diphenyl tetrazolium bromide) assay was carried out against HEK293 (human embryonic kidney), HeLa (cervical carcinoma), and MCF-7 (breast adenocarcinoma) cell lines. The concentration range of lupeol was 240-15 µg/mL. Lupeol at the concentration of 240 and 120 µg/mL have no antibacterial activity against Methicillin-resistant Staphylococcus aureus (MRSA) (ATCC BAA-1683). The antioxidant activity was dose-dependent, while cytotoxic activities were observed in HEK293, HeLa, and MCF-7 cells. This study was the first report on the extraction, isolation, and biological activities of lupeol, from the stem bark of G. lasiocarpa.
