“…80 One of the most interesting reports that were recently published, examines the concentration of sesamin in Cuscuta palaestina, a parasitic plant that grows over other plants, such as P. Farcta. 81 Among five very common plants (near east) host plants (P. farcta, Portulaca oleracea, Corchorus olitorius, Malva sylvestris and Cichorium intybus), C. Palaestina that grew on P. farcta contained the highest concentration of sesamin: 8.45 ppm. Despite this, researchers proved that sesamin is produced by the parasitic plant and not transferred to it by the hosting plant.…”

Prosopis farcta is a widespread weed in the Near East and its an invasive plant of southwestern parts of the USA. Despite being sufficiently studied in the past, some of its activities were not published. In this research, we studied the antifungal and anti-termite activities of four extracts of the plant aerial parts: aqueous, ethanolic, ethyl acetate and hexane. In addition, since the published reports of total phenolic content (TPC) are not consistent, we tested this as well. We also tested the potential of the aqueous extract of Carya illinoinensis as possible weed biocontrol against P. farcta. The n-Hexane extract had the highest antifungal and anti-termite activities. TPC was found around 13.9 mg of gallic acid equivalent for 1 g of dry ethanolic extract (highest). The attempts to use an aqueous extract of C. illinoinensis for weed biocontrol of P. farcta achieved very limited success

“…Plant-based nutrients and natural products have long been considered to be linked with human health and even evidenced to reduce risks of chronic human illnesses, such as inflammation [1,2,3], diabetes [4], cancer [5,6], and microbial-related diseases [7,8,9,10,11]. To date, herbal medicine is widely practiced in Palestine [12]. Well-reputed, it plays an integral part in the cultural heritage and public healthcare practices of the region.…”

Background: The wild population of spotted golden thistle, Scolymus maculatus, which belongs to the Compositae family, is believed to be one of the multi-curative wild plants mentioned in Flora Palaestina. This study aims to disclose the phytochemical composition, antioxidant potential, and antimicrobial activity of wild S. maculatus collected from the farms of Kabul, a village in northwest Galilee, for the first time. Methods: The phytochemical components of crude S. maculatus extracts from methanol, ethyl acetate, and n-hexane solvents were separated and identified using gas chromatography-mass spectrometry (GC-MS) in the electron impact (EI) mode. The free radical scavenging of the plant extracts was measured by DPPH assay. The microdilution test was used to determine the minimum inhibitory concentrations (MICs) of different S. maculatus extracts and to evaluate their antimicrobial activities. Results: Thirty-two phytochemicals were found in S. maculatus extracts including stigmasterol, γ-sitosterol, lupeol, lupeol acetate, and β-amyrin. Phytochemicals, such as 2-linoleoylglycerol, γ-sitosterol, β-amyrin, lupeol, (3α)-12-oleanen-3-yl acetate, and lupenyl acetate, were found to dominate the methanol extract. Most of these compounds were also observed in ethyl acetate and n-hexane extracts, but at different levels, in addition to some other minor compounds. The various extracts were investigated for their antioxidant and antimicrobial activity. The ethanolic and the methanolic extracts were shown to exhibit the highest free radical scavenging by DPPH assay with a half-maximally effective concentration (EC50) of 0.37 and 0.65 mg/mL respectively, while the other three extracts (aqueous, ethyl acetate and n-hexane) were less active and their EC50 (effective concentration at which DPPH radical was scavenged by 50%) were above 1.0 mg/mL. Moreover, MICs were determined to be effective against Staphylococcus aureus, Salmonella typhimurium, and Candida albicans microorganisms. Ethyl acetate and the ethanolic extracts are active against the three types of microorganisms at a minimum inhibitory concentration (MIC) of 0.5 mg/mL, while aqueous and the n-hexane extracts are inactive against Salmonella typhimurium. Conclusions: The results show that S. maculatus extracts are a rich source of compounds that can play an important role in human health, and in a broader context, in the treatment of various diseases, such antimicrobial and antioxidant-related ailments.

“…Accordingly, Stigmasterol was reported to have anti-arthritic, anti-venom, and glucose regulatory activities 45 . Nonetheless, the antiangiogenic activity of campesterol has already reported 46 . The presence of these compounds in the S. acuta leaf extract reestablishes the folklore importance of the plant leaves.…”

Sida acuta is one of the medically active plants used for the treatment of multifaceted diseases. However, an elaborated investigation on the phytochemical composition of the ethanolic extract of the leaves of this plant is yet to be deciphered. So, in this quantification of phytochemicals, in-vitro free radical scavenging activity, enzymatic and non-enzymatic antioxidant levels in the fresh leaves, HPTLC fingerprinting and GC-MS analysis in the ethanolic extract of Sida acuta leaves were done. In-vitro antioxidant activities were assayed using DPPH, ABTS, nitric oxide, hydroxyl radical and ferric ions, while ascorbic acid is used as the standard. The results indicated the presence of flavonoids, tannins, phenols, and alkaloids in a reasonably good amount which has substantiated the results of HPTLC. All the tested antioxidants were present prominently in the leaves, specifically catalase and glutathione peroxidase, which may be responsible for the prominent radical scavenging tendency of the extract against the tested free radicals. The GC-MS analysis observed the presence of 35 different compounds each belonging to different classes such as sterols, flavonoids, terpenes, heterocyclic aromatic compounds, phenols, fatty acids, vitamins, alkaloids, and sesquiterpenoids. The results indicate that the ethanolic extract of Sida acuta leaves collected from the Tuticorin District of Tamil Nadu is an effective scavenger of free radicals and has the potential to be used as a natural antioxidant which is attributable to the rich presence of its secondary metabolites.
