Unique distribution pattern and δ13C signature of des-A-triterpenoids from Lake Wuliangsu: Source and paleoenvironmental implications

•des-A-triterpenoids from Lake Wuliangsu show a unique distribution pattern and source.•des-A-triterpenoids can track submerged macrophytes in Lake Wuliangsu.•des-A-triterpenoids are impacted by aerobic bacteria activities and photodegradation. des-A-triterpenoids have been widely recognized as indi...
