STANDARDIZED Pink Guava extract

Psidium guajava

Pink guava is a common tropical fruit that is found in many parts of tropical and subtropical countries (including Malaysia). Pink guava is famous for its sweet and musky fragrance that have unique tropical notes of papaya, passion fruit and ripe pear. Many guava fruits are claimed to have a slightly sour taste, but pink guava is known to be the sweetest kind of all guava varieties.

Pink guava is called as “pink” due to its pink colour flesh that carries a phytochemical known as “carotenoid”. Carotenoids are beneficial antioxidants that keep you protected from diseases, aging and enhance your immune system. For its nutritional values, guava fruit is considered as one of the richest sources of vitamin C as it contains at least 3 times that of recommended daily allowance. Besides, guava contains other nutrients like potassium and pectin which can helps to lower blood cholesterol.

HEALTH BENEFITS

High in antioxidant

Randomized crossover design

Subject Psidium guajava L. and Psidium acutangulum D.C
Parameters analysed

(1) free radical DPPH scavenging

(2) ferric reducing antioxidant power assay (FRAP)

Outcomes

-Peel and pulp of guava extracts were tested to have remarkable antioxidant capacity.

-There was a significant correlation between estimated extractable phenol content and radical scavenging activity and ferric reducing antioxidant power.

-Guava extract inhibited the LDL oxidation in vitro.

-Guava could be a promising source of natural antioxidants.

Improves heart health

Randomized and single-blind trial

Subject Hypertension patients
Duration 12 weeks
Group (1) With guava diet (n = 61) (2) Without guava diet (n = 59)
Dosage 0.5-1.0 kg/day
Parameters analysed Blood lipid analysis
Outcomes Significant net decrease of total cholesterol (9.9%), triglycerides (7.7%), and blood pressure (9.0/8.0 mm Hg), with net increase in high-density lipoprotein cholesterol (8%) after 12 weeks of guava fruit consumption.
Group A (n = 61) Group B (n = 59)
At entry mean (SD) Change after 12 weeks mean (SD) At entry mean (SD) Change after 12 weeks mean (SD)
Cholesterol (mg/dL) 226(20) -26.6 223(18) -5.6

High-density lipoprotein (HDL) (mg/day) 44(8) +2.4 46(11) -1.2
Blood pressure (mm.Hg) 1) Systolic 2) Diastolic 163(6) / 106(4) -13.6 / -11.0 161(7) -4.6 / -3.0
Function Moderate intake of guava fruit in daily diet provides sufficient amount of dietary fibre, antioxidant vitamins and minerals. -Inclusion of high fibre food can decrease fat intake by decreasing lipoprotein metabolism and blood pressure, which subsequently may improve overall heart health.

Anti-microbial properties

In vitro lab experiment

Subject Bacteria strains – Staphylococcus aureus, Enteroaggregative E. coli (EAEC), Enterotoxigenic E. coli (ETEC), Enterobacter cloacae, Shigella flexineri, Enterococcus faecalis, Klebsiella, and Pseudomonas aeruginosa
Duration 24 hours
Group (1) Positive Control – norfloxacin (2) Negative Control – water (3) Apple extract (4) Guava extract
Dosage 30 microlitres of fruit extracts
Parameters analysed Zone inhibition in millimeter (mm)
Outcomes Extract of guava showed stronger antimicrobial activities than apple extract and was founeffectively inhibit the growth of Staphylococcus aureus, Enteroaggregative E. coli (EAEC), Enterobacter cloacae, Shigella flexineri, Enterococcus faecalis, Klebsiella, and Pseudomonas aeruginosa bacteria subcultures.
