It was first isolated in 1966 by Mehta et al. from Psoralea corylifolia seed and was called Bakuchiol based on the Sanskrit name Bakuchi of the plant.[1] Bakuchiol is mainly obtained from the seeds of the plant Psoralea corylifolia,[2][3][4] which is widely used in Indian as well as in Chinese medicine to treat a variety of diseases.[5] It has also been isolated from other plants, such as P. grandulosa,[6][7] P. drupaceae,[8] Ulmus davidiana,[9] Otholobium pubescens,[10] Piper longum [11] and Aerva sangulnolenta Blum.[12]

Even though the first complete synthesis of Bakuchiol has been described in 1973,[13] its first commercial use in topical applications did not occur until 2007 when it was introduced to the market under the trade name Sytenol® A by Sytheon Ltd.[14]

It has been reported to have anticancer activity in pre-clinical models, possibly due to its structural similarity with resveratrol.[15] One study in rats suggested that bakuchiol and ethanol extracts of the Chinese medicinal plant Psoralea corylifolia could protect against bone loss.[16]

Bakuchiol possesses antioxidant,[17][18] anti-inflammatory [19][20] and anti-bacterial [21] properties. Bakuchiol isolated from P. corylifolia has shown activity against numerous Gram-positive and Gram-negative oral pathogens. It was able to inhibit the growth of Streptococcus mutans under a range of sucrose concentrations, pH values and in the presence of organic acids in a temperature-dependent manner and also inhibited the growth of cells adhered to a glass surface.[22]

Despite having no structural resemblance to retinol, Bakuchiol was found to have retinol functionality through retinol-like regulation of gene expression.[23] In 2018, a randomized, double-blind, 12-week clinical study with 44 volunteers demonstrated that Bakuchiol is comparable with retinol in its ability to improve photo-aging (wrinkles, hyperpigmentation) but has a better skin tolerance.[24]

Bakuchiol has been found to possess antiandrogenic activity in prostate cancer cells, which inhibited cell proliferation.[25]
