Therefore guava fruit is often made with red Guava juice is believed to have properties to increase endurance for patients with dengue fever.

Special leaves of guava, studies that have been done generally usefulness as ainti diarrhea. In addition, Guava has efficacy as an anti-inflammatory, anti-mutagenic, anti-microbial and analgesic. Beberepa chemical compounds contained in guava, among others, polyphenols, carotene, flavonoids and tannins. With the birth of the compound was estimated guava leaf also has a strong antioxidant activity of efficacy in treating various diseases, says Susi Indariani, researcher of medicinal Study Center Institute for Research and Community Empowerment Bogor Agricultural University (IPB).

Susie Indariani then doing research efficacy of guava leaves as an antioxidant. The study, he gave the title Antioxidant Activity Test Guava Leaf Extract (Psidium guajava L) aims to determine the antioxidant aktibitas guava leaf extract as well as compare the antioxidant potential of several types of local Guava Leaf in order to obtain local Guava leaf types that have the best antioxidant potential.

â € œDalam research I did several tests that test the antioxidant activity chemically with thiocyanate method, testing of chemical antioxidants ektivitas tiobarbiturik method (TBA), and analysis of physics, chemistry and microbiology selected extracts. Susie uses raw materials of local red guava leaf and guava local putil obtained by collecting from a tree that grows in the garden-courtyard house in the area Bantar Goat Bogor. The leaves are dried before the analysis first.

As a result, the test using the thiocyanate method, white guava leaf extract has a local protective factor (protection capabilities) approached the vitamin E or tocopherol is equal to 1.10. Tocopherol itself has a protective factor of 1:16. While the red guava leaf lower protective factor that is less than 1. In pegujian using TBA method, the ethanol extract of guava leaves can inhibit local white lipid oxidation to 94.19% of the control that was not given the antioxidant. This means that the leaves of guava seeds proved to have antioxidant capabilities. Susi also examine the content of local white guava leaf. Phytochemical test results showed guava leaf extract compounds contained in the extract are tannins, phenols, flavonoids, quinones, and steroids. Regarding the active compounds that have activity aktioksidan Susie said, â €? Need to research more about it.
