ANTI HYPERTENSIVE ACTIVITY OF SOURSOP

 

Annona muricata L. is a tropical tree that is used in traditional medicine around the world. The high content of flavonoid, alkaloid, acetogenin, phenolic, and lipophilic compounds of this tropical tree forms the basis of its traditional medical uses.

According to 49 research articles studied, the pharmacological properties of Soursop are reported to include 6% antihypertensive properties.

In a study carried out in Jamaica, it was found that Annona muricata shows antioxidant and antihypertensive properties through Angiotensin-I-converting enzymes in vitro. The suggested hypotensive mechanism of A. muricata takes action through the blockage of calcium ion channels, that lowers the blood pressure. The hypotensive effects of A. muricata are not mediated through muscarinic, histaminergic, adrenergic, and nitric oxide pathways, but through peripheral mechanisms involving antagonism of Ca(2+).

Possible Mechanisms of Action of the Hypotensive Effect of Annona muricata (Soursop) in Normotensive Sprague Dawley Rats. Pharm. Biol. 2012, 50, 1436–1441.)

SOURSOP IN CANCER ADJUVANT THERAPY

  Annonaceous Acetogenins are the most valuable phytochemicals present in Soursop/ Laxmanphal, scientifically known as Annona muricata . Annonaceous acetogenins typically are derivatives of long chain fatty acids that are selectively toxic to Cancer cells, including multidrug resistant Cancer cells. Scientific research carried out by Hadisaputri et al (2021) conclude that Annona muricata leaf extract is responsible for the induction of apoptosis of breast cancer cells. This apoptosis is majorly due to reduction in the integrity of mitochondrial cells. Cancer cells may develop Multi Drug Resistance (MDR), a phenomenon in which Cancer cells develops resistivity against the the specific drug being used in the Cancer treatment. Acetogenins (ACG) in Soursop are found to be cytotoxic to these Drug Resistant Cancer cells. As a result, these Cancer cells undergo death and decay, preventing the spread of Cancer to other parts of body (Metastasis). Annonaceous acetogenins induce cy...

SOURSOP - AN EXCELLENT ANTIOXIDANT

What is Oxidation ? Oxidation is a chemical process where molecules lose electrons, often resulting in the formation of unstable Free Radicals. To get stabilized, these free radicals further snatch electrons from the nearby healthy cells, making them unstable. It's a chain reaction, making the cell and its ingredients unstable, resulting in cell damage.  What are Antioxidants ? Antioxidants are the substances that donate electrons to Free Radicals, making them stable, preventing probable cell damage.  Oxidative Stress Condition  is the tug of war between oxidation-causing agents and antioxidants for electrons . This is a condition when there is an imbalance between the amount of  Reactive Oxygen Species (ROS)  and  Antioxidants . Increasing scientific evidence is concerning, as it suggests that ROS and Oxidative Stress play crucial roles in developing chronic diseases like pathogenesis, such as Cancer, neurodegenerative diseases, and cardiovascular and...
