Seed Extract of Psidium guajava as Ecofriendly Corrosion Inhibitor for Carbon Steel in Hydrochloric Acid Medium

Spectroscopic and chromatographic evaluation of solvent extracted guava seed oil

“…[12] Guava seed extract has been reported as corrosion inhibitor (decreases corrosion rate of a material) for carbon steel in HCl (acidic) medium. [13] It has been reported that guava seed posses significant amount of tryptophan, methionine, linoleic acid and fiber content confines its use as wheat flour alternate in the preparation of cookies. [14] The plants contain a range of fatty acids with different structure commonly found in edible oils, and some of them are highly beneficial for health.…”

Inhibition of mild steel corrosion using Jatropha Curcas leaf extract

“…Hence, naturally occurring compounds from plants origin have been a subject of interest for researchers because of their abundant availability, cost effectiveness and environmentally friendly [4]. Several studies have been carried out on the use of these naturally occurring compounds as corrosion inhibitors for metals in different media [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

Punica granatum leave extract as green corrosion inhibitor for mild steel in Hydrochloric acid

“…Various parts of plants -seeds, fruit, and leaves, were extracted and used as corrosion inhibitors [1][2][3][4][5][6][7]. Punica granatum, commonly known as pomegranate is reported to be a rich source of anthocyanins (delphinidin, cyaniding, and pelargonidin), phenolic compounds (including hydrolysable tannins such as punicalin, pedunculagin, punicalagin, gallagic, and ellagic acid), and organic acids alleged to be responsible for its medicinal properties [8,9].…”
