This study was performed to clarify the whitening effects of anthricin on the B16F10 cell line. In order to elucidate the whitening effects of anthricin on the B16F10 cell line, cell viability, messenger ribonucleic acid (mRNA) expressions, tyrosinase activity assay, and melanin production assay were measured. The effects of anthricin on tyrosinase-related protein 1(TYRP1)/TYRP2/tyrosinase (TYR)/microphthalmia-associated transcription factor (MITF) mRNA expressions and melanin content were determined. Quantitative real-time RT-PCR showed that anthricin decreased the mRNA expression level of TYRP1/TYRP2/TYR/MITF genes and melanin production contents than α-MSH-treated B16F10 cells. The tyrosinase activity assay revealed that anthricin decreased the melanin production on the B16F10 cells. These data show that anthricin increases the whitening effects on the B16F10 cells; thus, anthricin is a potent ingredient for skin whitening. Thus, further research on the mechanism of action of anthricin for the development of not only cosmetics, but also healthy food and medicine should be investigated.

Anthricin (Deoxypodophyllotoxin), a naturally occurring flavolignan, has well known anti-cancer properties in several cancer cells, such as prostate cancer, cervical carcinoma and pancreatic cancer. However, the effects of Anthricin are currently unknown in oral cancer. We examined the anticancer effect and mechanism of action of Anthricin in human FaDu hypopharyngeal squamous carcinoma cells. Our data showed that Anthricin inhibits cell viability in a dose- and time-dependent manner ($IC_{50}$ 50 nM) in the MTT assay and Live & Dead assay. In addition, Anthricin treated FaDu cells showed marked apoptosis by DAPI stain and FACS. Furthermore, Anthricin activates anti-apoptotic factors such as caspase-3, -9 and poly (ADP-ribose) polymerase (PARP), suggesting that caspase-mediated pathways are involved in Anthricin- induced apoptosis. Anthricin treatment also leads to accumulation of the pro-apoptotic factor Bax, followed by inhibition of cell growth. Taken together, these results indicate that Anthricn-induced cell death of human FaDu hypopharyngeal squamous carcinoma cells is mediated by mitochondrial-dependent apoptotic pathway. In summary, our findings provide a framework for further exploration on Anthricin as a novel chemotherapeutic drug for human oral cancer.

Quality evaluation of Magnoliae Flos and Anthrici Radix was studied to ensure their safety and efficacy, which was based on physico-chemical determination of the content of total ash, acid insoluble ash and diluted ethanol-soluble extract. In addition, quantitative analysis of magnolin and anthricin by HPLC suggested that the content of magnolin and anthricin in Magnoliae Flos and Anthrici Radix was $31.09{\pm}15.74%$ and $1.08{\pm}0.85%$.

Bioassay-guided chemical investigation of the roots of Anthriscus sylvestris (L.) Hoffm. resulted in the isolation of nine compounds, whose structures were determined by spectroscopic methods. Compound 1 was isolated from this plant for the first time and compounds 3 and 9 were first found from this genus. Different polar fractions of A. sylvestris extract and compounds 1, 6-8 and 9 were evaluated for antitumor activities against HepG2 (human hepatocellular carcinoma), MG-63 (human osteosarcoma cells), B16 (melanoma cells) and HeLa (human cervical carcinoma cells) lines by the MTT method. The petroleum ether fraction of A. sylvestris extract exhibited excellent inhibitory activity with an $IC_{50}$ value of $18.3{\mu}g/ml$. Among the isolates from the petroleum ether fraction, compound 7 showed significant inhibition against the growth of the four tumor cells with $IC_{50}$ values ranging from $12.2-43.3{\mu}g/ml$.
