“…Many studies showed that compounds such as polysaccharides from Padina spp. increase the root and shoot length of plants [54][55][56]. In addition, Hernández-Herrera et al [45] assessed the effects of polysaccharide-enriched extracts from P. gymnospora on the growth of tomato and mung bean plants and found that the extracts resulted in significantly higher radicle length in tomato and mung bean plants.…”

Seaweeds are used in traditional agriculture practices because of their beneficial effects. Recently, the rising demand for organically grown foods has amplified the use of organic fertilizers such as seaweed extracts. Despite their beneficial effects, few studies have reported information about compounds in seaweed extracts that are responsible for these benefits. Thus, the aim of this study was to evaluate the potential relationships between the components and secondary metabolites in four seaweed liquid extracts from Eisenia arborea, Macrocystis pyrifera, Padina caulescens, and Sargassum horridum and their biostimulant activity through changes in the germination, growth, and protein content of tomato seedlings (Solanum lycopersicum). The E. arborea and S. horridum extracts showed similar compositions (ash, organic carbon, bicarbonates, and chlorides), minerals (Ca, Fe, and Cu) and secondary metabolites (triterpenes and saponins), albeit with different component concentrations. The chemical composition of the P. caulescens extract was significantly different from those of the other extracts; it was characterized by high levels of total nitrogen, phenols, and carbohydrates. Almost all seaweed extracts had beneficial effects on seed germination and seedling length, except the S. horridum extract that inhibits germination. The hierarchical clustering plots and principal component analysis indicated that germination and protein content are related to the presence of sterol. Shoot length was closely related to mineral levels (K, Zn, B, Na) and the C:N ratio, whereas radicle length was closely related to the content of nitrogen, carbohydrates, phenols, and flavonoids in the seaweed extracts. However, the underlying mechanisms are still unclear and require further studies.

Ethanol extracts of Caulerpa racemosa, Dictyopteris acrostichoides, Halimeda opuntia and Polycladia myrica, were tested for their cytotoxicity against HepG2 (human hepatoma), MCF-7 (human breast adenocarcinoma), and Caco-2 (human colon adenocarcinoma) cells. Dictyopteris acrostichoides displayed cytotoxicity against HepG2, MCF-7 and Caco-2 with IC50 values of 11.65, 9.28 and 16.86 µg/mL, respectively in comparison to doxorubicin as a positive control, (IC50 = 5.72, 5.17 and 5.81 µg/mL, respectively). LC-HR-ESI-MS metabolic profiling of the D. acrostichoides extract characterized seventeen metabolites (1–17). In silico analysis indicated 1-(3-oxo-undecyldisulfanyl)-undecan-3-one (16) was the most active EGFR inhibitor, while 1-(3-Oxo-undecyldisulfanyl)-undecan-3-one (16) and di(3-acetoxy-5-undecenyl) disulfide (17) were the most active VEGFR inhibitors. Furthermore, the ethanol extract of D. acrostichoides was tested against epidermal growth factor receptor (EGFR) kinase (IC50 = 0.11 µg/mL) compared to lapatinib as a positive control, (IC50 = 0.03µg/mL) and against vascular endothelial growth factor (VEGF) (IC50 = 0.276 µg/mL) compared to sorafenib as a positive control, (IC50 = 0.049 µg/mL).

“…Numerous sources, including plants, animals, marine life, and ancient ecosystems, are rich in phytochemicals [3]. For many years, traditional medical techniques have been used in this field [4,5]. The plant genus Rhamnus has been utilized in traditional medicine to treat a wide range of diseases in many different countries [6].…”

Traditional medicine remains an alternative care option for most poor countries due to its inherent traits, unique and holistic approaches, accessibility, and cost. The current review aims to provide a comprehensive and up-to-date compilation of documented traditional medicinal uses, phytochemicals, and pharmacological activities of invasive R. cathartica and R. disperma, as well as valuable information to support its use as an alternative medicine in future healthcare practice. The genus Rhamnus, commonly called buckthorns, belongs to the family Rhamnaceae. It is considered a fruit and is of nutritional interest owing to its low calories. This review demonstrated that R. cathartica and R. disperma have multifaceted pharmacological potential. Studies examining this compound antioxidant, anticancer, anti-inflammatory, antiviral, and antibacterial characteristics have drawn attention to its effectiveness. Only a small number of research have looked specifically at R. disperma; instead, most studies have looked at R. cathartica, leading to generalized conclusions attributed to the group of compounds rather than the individual component. This paper covers Egyptian Buckthorns' chemistry and pharmacological potential, including their mechanism of action whenever applicable. .
