Natural wax from non-medicinal aerial part of Codonopsis pilosula as a biolubricant

To solve the problems of unsustainability and low biodegradability of mineral oil-based lubricants, an agro-waste to biolubricant supply chain was proposed. A plant wax was extracted from the non-medicinal part of Codonopsis pilosula, and its composition, thermal stability, and lubrication behaviours were investigated. The plant wax was composed mainly of the esters of fatty acids and triterpenes. The natural wax showed good thermal stability...
