Saussurea costus is from medicinal plants and have therapeutic properties that were recorded in a variety of medical functions. The usage of biomaterials in the synthesis of nanoparticles is an essential strategy in green nanotechnology. Iron oxide nanoparticles (IONPs) were composed in the stage of (2:1, FeCl2: FeCl3) solution by using the aqueous extract of Saussurea costus peel in an eco-friendly method to evaluate their antimicrobial property. The properties of the obtained IONPs were evaluated using a scanning (SEM) and transmission (TEM) electron microscope. The mean size of IONPs discovered by Zetasizer varies between 100 and 300 nm, with a mean particle size of 295 nm. The morphology of IONPs (γ-Fe2O3) was determined to be nearly spherical and prismatic-curved. Moreover, the antimicrobial property of IONPs was assessed with nine pathogenic microbes, revealing that the nanoparticles have antimicrobial activities with Pseudomonas aeruginosa, Escherichia coli, Shigella sp., Staphylococcus sp. and Aspergillus niger, with possible applications in the therapeutic and biomedical fields.

“…From a botanical point of view, the presence of appendages to the style arms and of a basal tuber is a distinctive feature for this genus (Davies, 1980a). Phytochemical analyses of Gynura species have revealed the presence of diverse constituents including alkaloids, phenolic compounds (especially quinic acid derivatives), flavonoids, steroids, glycosides and terpenoids (Chandradevan et al, 2020;Do et al, 2020).…”

“…Several Gynura spp. are used for culinary purposes and/or employed in traditional medicine for the treatment of migraine, fever, rashes, inflammation, rheumatism, herpes, constipation, hypertension, hemostasis, kidney disease, diabetes mellitus and cancer (Do et al, 2020;Hong et al, 2020;Lu et al, 2012;Xian and Juxian, 2002). The long historical use of consuming Gynura species, combined with their oral safety and their broad variety of phytochemicals, suggest that they are invaluable functional foods.…”

“…Several biological activities have been reported for plant extracts, which show antiviral, antibacterial and antifungal properties [9][10][11][12]. Medicinal plants, which contain a wide range of phytochemicals are one of the most readily available sources of such compounds [13][14][15][16][17]. Sausurea costus (S. costus) is well known in Islamic medicine, and is recorded in the holy hadiths that Prophet Muhammad (peace and blessings be upon him) said [18].…”

Saussurea costus had a wide range of antimicrobial activities which used as alternative for synthetic preservatives that threaten human health. This study aimed to identify the bioactive compounds in S. costus extract (SCE) and to evaluate its antimicrobial activity against some pathogenic microorganisms. HPLC and GC-MS were used to quantify the bioactive compounds in SCE. The results indicated that ethanol and ethyl acetate extracts had the highest levels of polyphenols followed by n-butanol, and then n-hexane extracts. The main phenolic compounds are Naringenin, Chlorogenic acid, Ferulic acid, Ellagic acid, Gallic acid and coffeic acid followed by taxifolin, catechin, syringic acid, methyl gallate, vanillin, kaempferol, cinnamic acid and rutin. GC-MS results showed 14 compounds in S. costus extract. The antibacterial activity of S. costus ethanol extract increased by increasing the concentration of extract from 10 µl to 50 µl for each wells .The inhibition zones were 13 mm and 23mm for S. typhi and Staphylococccus aureus, respectively. Gram (+ve) bacteria found to be more sensitive to SCE than Gram (-ve) bacteria. Similarly; the antifungal activity was increased by increasing the concentration of SCE the inhibition zones were 15.5 mm and 22.5 mm for P. verecossum and A. ochraceous, respectively. A. ochraceous appeared to be more sensitive towards all concentration of the extract. The minimum inhibitory concentration (MIC) of SCE for both bacteria and fungi strains ranged from 0.08 -0.3 mg/ml and 0.25 -1.17 mg/ml, respectively. The results revealed that the SCE can play an important role against the human multi-drug resistant pathogens and can alternate the antibiotics as well as chemical preservatives to control infection and food spoilage contaminants.
