               Abstract
                  Helicteres hirsuta has been utilized in Vietnamese traditional medicine for the treatment of
               liver diseases. Despite numerous investigations on this plant, there is a deficiency of knowledge
               on the chemical properties and pharmacological effects of the aqueous extract of H. hirsuta,
               which  is  the  traditional  usage.  This  study  compared  the  hepatoprotective  activities  and
               antioxidant properties of ethanol and water extracts of H. hirsuta in in vitro models, revealing
               that  the  water  extract  (HEW)  demonstrated  significant  efficacy.  Phytochemical  study  was
               conducted  on  HEW  to  identify  danshensu,  rosmarinic  acid,  and  tiliroside  as  the  principal
               compounds, along with five flavonoids and two phenolic compounds that were isolated from
               H. hirsuta for the first time. An HPLC method for the simultaneous quantification of three
               markers of HWE was established for the quality control of the extract utilized in the in vivo test
               to evaluate its hepatoprotective properties. The HWE at doses of 412.5 mg/kg and 825 mg/kg
               has hepatoprotective properties against paracetamol-induced liver injury in mice. The HWE
               contributed to lowering MDA levels, enhancing GSH, diminishing liver enzymes (AST, ALT
               and ALP), and total  bilirubin,  as well as reducing both  macroscopic and microscopic liver
               damage.  It  is  concluded  that  HEW  demonstrates  hepatoprotective  effects  similar  to  those
               observed in traditional medicine. The effects may be elucidated by the properties of identified
               constituents in HWE. The results of this study could be the scientific evidence for developing
               the healthcare product of H. hirsuta in the future.
