• Mainly Lignans are responsible for Hepetoprotective and anti-hepatitis activities.

• Constituents contribute at most to its hepetoprotective activity are phyllenthin and hypophyllanthin.

• Both have exhibited a significant protection against CCl4

- and galactosamine-induced elevation in liver transferase enzymes levels and significantly increased protein levels.


• They have also reported to inactivate hepatitis B, both in-vitro and in-vivo.

• Phyllanthin possesses anti-viral activity against HIV by inhibiting reverse transcriptase.

• Phyltetralin, nirtetralin and niranthin exhibited anti-inflammatory activity by inhibiting carrageenan-induced pawoedema and neutrophil influx



Structures of lignans:

• Summery:

• P. niruri has many effective traditional uses for a wide variety of diseases.

• The phytochemicals exhibited different structural characteristics with various pharmacological actions:– lignans had excellent hepatoprotective and anti-

viral properties.


• Summery:• Continued…– Terpenes exhibited anti-cancer, as well as anti-

microbial activity.– Flavonoids showed anti-oxidant activity.– Alkaloids exhibited anti-spasmodic activity.

• There have been no side effects or toxicity reports from many years of research.
