Introduction: EucommiaulmoidesisadeciduoustreenativetoChinaandisrenownedforitsstrong,elasticbarkandfoliage.TheleavesofEucommiaulmoidesarehighlyvaluedintraditionalChinesemedicineduetotheirrichcontentofbioactivecompounds,includinglignans,phenolics,andflavonoids.Thesecompoundsarebelievedtopossessvarioushealthbenefits,includinganti-aging,anti-inflammatory,andantihypertensiveproperties.TheecologicalandphysiologicalcharacteristicsofEucommiaulmoidesleavesvarysignificantlyacrossdifferentvarieties,influencingtheirphotosyntheticperformanceandmedicinalcomposition.Hence,understandingthesevariationswillaidinharnessingthefullpotentialofEucommiaulmoidesasamedicinalherb.
