Evaluation of Hepatoprotective and In-vitro Cytotoxic Activity of Leaves of Premna serratifolia Linn

Abstract

Premna serratifolia is used by the traditional practitioners as cardiotonic, antibiotic, anti-coagulant, stomachic, carminative, hepatoprotective, antitumor etc. The present study aims in the evaluation of hepatoprotective and in-vitro cytotoxic activity of alcoholic extract of leaves of Premna serratifolia Linn. Hepatoprotective activity is studied by carbon tetrachloride induced hepato-toxicity in rats and the in-vitro cytotoxic activity is carried out by tryphane blue exclusion method using EAC cell lines. The degree of protection in hepatoprotective activity has been measured by using biochemical parameters such as serum glutamate oxalate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), bilirubin and total protein. The results suggest that the alcoholic extract at the dose level of 250mg/kg has produced significant  (p < 0.001) hepatoprotection by decreasing the activity of serum enzymes, bilirubin, and lipid peroxidation which is comparable to that of standard drug silymarin. The alcoholic extract also does exhibit the IC50 value of 75µg/ml which indicates the significant in-vitro cytotoxic activity of the extract. It is concluded that alcoholic extract of leaves of Premna serratifolia Linn is not only an effective hepatoprotective agent, but also possesses significant antitumor activity.  Keywords: Premna serratifolia Linn; Alcoholic extract hepatoprotective; In-vitro cytotoxic activity.  © 2009 JSR Publications.

Cytotoxic activity of isolated constituents from leaves of <i>Premna serratifolia</i> on MCF-7 and HT-29 cell lines

“…Pharmacologically, it has been reported to have activities such as hepatoprotective (Vadivu et al, 2009), immunomodulatory, cardiac stimulant, antibacterial, cytotoxic, antiarthritic, anti-inflammatory (Biradi and Hullatti, 2013), anti-diabetic (Mujumder et al, 2014), anti-oxidant (Mali et al, 2014), anti-obesity and used in treatment of tumors (Cragg and Newman, 2005).…”

Determination of Safety Margin for Hepatotoxic Effect of Mentha Longifolia Essential Oil in Rat

“…Unfortunately, so many deaths occur annually from the liver cirrhosis [12]. Liver injuries are commonly caused by viruses, environmental toxicants, drugs and overuse of alcohol that finally leads to different types of hepatic disorders [13,14].…”

In Vitro α-Glucosidase Inhibitory Activity of Ethanol Extract of Buas-buas (Premna serratifolia Linn)

“…Kandungan metabolit tersebut juga terdapat pada Buas-buas (Premna serratifolia Linn) seperti alkaloid, flavonoid, tanin, steroid, saponin, terpenoid, dan fenolik (Wahyuni et al, 2014). Metabolit sekunder yang terdapat pada Premna seratifolia Linn dapat dimanfaatkan sebagai tanaman obat, yaitu : stimulus jantung , hepatoprotektif pada daun (Vadivu R et al, 2009) dan ekstrak akarnya (Sigh CR et al, 2011), ekstrak etanol kulit kayu dan kayu memiliki efek kardioprotektif (Rajendran R and Basha NS, 2008).…”
