Phytosterol, Lipid and Phenolic Composition, and Biological Activities of Guava Seed Oil.

Plant seeds have been found to contain bioactive compounds that have potential nutraceutical benefits. Guava seeds () are by-products in the beverage and juice industry; however, they can be utilized for a variety of commercial purposes. This study was designed to analyze the phytochemicals of the -hexane extract of guava seed oil (GSO), to study its free-radical scavenging activity, and to monitor the changes in serum lipids and fatty acid profiles in rats that were fed GSO.

Linoleic acid-rich guava seed oil: Safety and bioactivity.

Guava (Psidium guajava) is a widely consumed fruit and has been commercialized in markets. The seeds are by-products of the processing procedures performed by the commercial guava juice industry. They are considered a nutritional resource that has been poorly utilized as they contain essential fatty acids such as linoleic acid (LA) and phenolics in abundance.

Acute and chronic oral toxicity of a partially purified plaunotol extract from Croton stellatopilosus Ohba.

Plaunotol, an acyclic diterpenoid with highly effective antigastric ulcer properties, has been commercially isolated from leaves of Croton stellatopilosus Ohba. This Thai medicinal plant was traditionally used in the form of crude extracts, suggesting that it is possible to administer these plaunotol-containing extracts without toxicity. To confirm its safety, the oral toxicity of a partially purified plaunotol extract (PPE) was evaluated in vivo.
