A high-performance liquid chromatographic (HPLC) analysis showed conclusively that of the eight catechin monomers and caffeine found in the original extracts, only four components were responsible for the inhibition of MS. The decreasing adsorption capacity of monomers on MS is related to the stereochemistry of molecules and the number of phenolic groups, and it is as follows: epigallocatechin gallate\u003cepicatechin gallate adsorption of green tea extract constituent was found to follow langmuir isotherm and the calculated gibb free energy values indicated physisorption inhibitor over ms surface. supported well by potential zero charge molecular surface energy-level calculations.\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783847373902\"\u003e\u003ch3\u003eCorrosion inhibition behavior of green tea on mild steel\u003c\/h3\u003e\u003c\/div\u003e\u003c\/epicatechin\u003e\u003c\/p\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783847373902","offer_id":39491139502173,"sku":"9783847373902","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/fdf75977-4f0a-4c60-b7b1-6ba6a1ceb649.jpg?v=1755405942","url":"https:\/\/shop.autorenwelt.de\/products\/green-tea-extracts-von-nofrizal-syamsudin-afidah-abdul-rahim-und-bahruddin-saad","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
