Abstract Sea cucumbers, members of the echinoderm class Holothuroidea, are marine invertebrates with ecological significance and substantial commercial value. With approximately 1700 species, these organisms contribute to ecosystems through nutrient cycling face various threats, including overfishing habitat loss. Despite their importance, they extensively exploited for diverse applications, from seafood pharmaceuticals. This study investigates sea cucumbers' nutritional profile bioactive elements, emphasizing role as sources essential compounds potential health benefits. The demand especially in dried form, is significant, prompting exploration into drying techniques. Examining global trade cucumbers highlights economic importance conservation challenges face. Conservation efforts, such awareness campaigns international collaboration, evaluated steps combating illicit promoting sustainable stewardship cucumber populations. Practical Application Around species were identified vital scavengers Holothuroidea class. High value due benefits, particularly demonstrated inhibitory effect against types cancer. “Beche‐de‐mer” holds a 90% market share regarded luxury food item Southeast Asian countries. Due overexploitation, classified Schedule I under Wildlife Protection Act (WPA) India, implementation blanket ban on harvesting ensure its conservation.

Phedimus aizoon has been utilized as a medicinal plant in Asia. However, the production of phytochemical-rich extracts from P. and evaluation their bioactivity are limited. Herein, were prepared by ultrasound-assisted extraction aizoon, with high yield 16.56%. The contained about 126 mg phenolics 31 flavonoids per g extracts. chromatographic analysis (GC-MS HPLC analyses) identified 19 notable phytochemicals including pentacosane, hexadecanoic acid, gallic vanillic quercetin. acid content was relatively at 2.75 mg/g. compounds known to have various bioactivities, such antioxidant, antibacterial, antifungal activities. In fact, exhibited antioxidant activity 24–28% that ascorbic acid. addition, it showed antibacterial against both Escherichia coli (Gram-negative bacteria) Staphylococcus aureus (Gram-positive bacteria). This study highlights deserves attention natural bioactive substance emphasizes need for applications aizoon.

In vitro Assessment of Antischistosomal Effect of the Marine Hyrtios sp. Sponge Extract against Schistosoma mansoni Adult Worms

Egyptian Journal of Aquatic Biology and Fisheries, Год журнала: 2024, Номер 28(2), С. 799 - 823

Опубликована: Март 1, 2024

Schistosomiasis is a prevalent epidemic disease in Egypt. As result of the exclusive use praziquantel (PZQ) treatment schistosomiasis, parasite may become resistant to medication. Accordingly, there has been growing interest research with aim developing novel antischistosomal medicines from natural sources. The marine Hyrtios sponge exhibits bioactive compounds, qualifying it explore drugs. Hence, current study aimed assess vitro activity extract (HSE) against schistosomiasis through detection mortality and tegumental alterations S. mansoni adult worms. rates worms exceeded 50% after 2 3 hours exposure concentration 200µg/ ml HSE. After 24 hours, surpassed at concentrations both 100 ml. Additionally, 36 48 reached above across ranging 60 Furthermore, 48h, rate 100% concentration. exposing HSE for 24h, lethal values (LC50 LC90) were 115.40 241.19µg/ ml, respectively. These became 59.36 LC50 144.11µg/ LC90 48h exposure. Scanning electron microscopy revealed morphological changes male female 200μg/ following 48-h compared control group. Morphological abnormalities included swollen or flattened bodies, self-coiling contractions, tegument shrinkage, invaginations, erosion, deformed gynechophoric canal, distorted suckers, smooth tubercles blebs between them. body displayed alterations, including body, shrinkage ventral sucker, pitted corrugation, folds, wrinkles, erosions, addition absence spines. death caused by could be associated its effect on their surface related existence different antioxidant phytochemicals like alkaloids, saponins, phenolics, flavonoids this extract. In conclusion, an effective impact can considered adjuvant medication PZQ infection.
