Takeaways from study on anti-aging potential of pigmented rice, callus extracts – CosmeticsDesign-Europe.com

Rice contains a number of compounds helpful in anti-aging including vitamin E homologues, phenolic acids, anthocyanins and procyanidins. The level of bioactive pigments in rice depends on the species’ color.

A research team out of Thailand, Vitchit et al, was recently published in Cosmetics exploring the levels of key anti-aging activities in rice extracts of three different species of rice, unpigmented Hommali rice, red Munpu rice and black Niawdum rice.

Vitchit et al also compared the performance of plain rice seeds and rice calli culture,

“They are interesting because of their robust anti-oxidant activity,”​ Vitchit et al said. “Calli derived from rice embryonic cells have previously been shown to exhibit anti-aging properties.”

Evidence for the calli culture technique

Vitchit et al said calli are plant stem cells that are genetically capable of growing an entirely new plant and have significant proliferation and differentiation potential. 

The research team also notes that callus derived from several plants generated higher levels of bioactive ingredients like anthocyanins, procyanidins, flavonoids and phenolic acids, which are also present in rice.

“The investigation of bioactive compounds in the rice callus extract indicated that the condition for cultivation enhanced phenolics and amino acids,”​ Vitchit et al said. “The rice callus extracts appeared to have potent antioxidant and anti-aging activities.”

Callus tissue performed better than standard rice extracts in many but not all tests performed by Vitchit et al, as well as in other studies on peppers, tomatoes and grapes, among others.
