“…Some new peaks were also observed at 3343, 3291, and 1341 cm −1 corresponding to strong stretching alcohol (O–H), strong stretching alkyne (C–H), and medium bending phenol (O–H) respectively. Similar findings can be observed in the literature [ [29] , [30] , [31] , [32] , [33] ]. Table 1 shows the presence of bio-compounds in the synthesized nanoparticles.…”

Kaempferia parviflora Wall. Ex Baker is commonly known as 'black ginger' which belongs to the family Zingiberaceae. These are mostly found in the subtropical and tropical areas of Asia. It bears various pharmacological properties such as anticancerous, anti-allergic, antiinflammatory, antioxidant and antimicrobial. Upon the reports we reviewed the plant aromatic rhizomes contained important phytochemicals as terpenoids and flavonoids. Silica gel column chromatography and high performance liquid chromatography analysis has identified methoxyflavonoids in its rhizome extract which can be used in cosmetics as natural anti-aging agent. These extracts have shown anticancer activities against cervical cancer, pancreatic cancer, gastric ulcer, ovarian cancer etc. There are several reports on the cytotoxic activities of rhizome extracts against different cancer cells which are an alternative way for cancer therapy. Also these plants are depleting in forests for which major steps must be taken for its conservation thereby improving its drug yielding potential which would help in various medicinal ways. Thus, the present report deals with numerous pharmacological activities of this plant which has to be improved further to retain its quality for pharmaceutical uses.INTRODUCTION: Kaempferia parviflora of Zingiberaceae family is an important ginger plant which is also known as Thai ginseng or krachaidum. It is widely distributed in India,

“…The biological approach has attracted special interest when AuNPs are intended for use in areas such as biomedicine and the environment [17][18][19], as these methods are safe, non-toxic, and eco-friendly [20,21]. In biological synthesis methods, also called biosynthesis or green synthesis, an organism is used to reduce metal ions and subsequent stabilization of the nanoparticles [22,23]. Bacteria, fungi, plants, and algae have been reported for these purposes [10,24,25].…”

Sargassum species-based extracts were used to carry out the synthesis of homogeneous gold nanoparticles. Various techniques were used to determine the characteristics and composition of the nanoparticles. The UV-Vis results showed that the 50% water/ethanol extract had the most reducing agents and stabilizers. Therefore, this type of extract was used to synthesize nanoparticles and for their subsequent characterization. Crystallinity and crystal size were evaluated using X-ray diffraction. Size and morphology were analyzed using scanning electron microscopy, showing that the gold nanoparticles were mostly spherical, with a size range of 15–30 nm. The catalytic activity of the gold nanoparticles was evaluated through the degradation of organic dyes: methylene blue, methyl orange, and methyl red. The degradation rates were different, depending on the nature of each dye, the simplest to degrade was methylene blue and methyl red was the most difficult to degrade. The results indicated that the use of Sargassum spp. for the synthesis of gold nanoparticles has potential in the remediation of water that is contaminated with organic dyes. Moreover, given the recent serious environmental and economic problems caused by the overpopulation of Sargassum spp. in the Mexican Caribbean, the findings hold promise for their practical and sustainable use in the synthesis of nanomaterials.
