Matricaria chamomilla L. has been used as a bath agent in Europe because of its sterilization effect on the skin. Flowers contain terpenes, flavonoids are effective in relieving inflammation. Matricaria chamomilla L. has been reported to have various drug efficacies such as sedation, anti-diabetic effect and anti-arthritic effect, but there is little research on the scientific efficacy of whitening effect. The purpose of this study was to examine the whitening effect of Matricaria chamomilla L. extract and to investigate the mechanism of inhibition of melanogenesis. The extracts were used to determine tyrosinase inhibitory activity. The tyrosinase inhibitory activity of extracts was ineffective for water extract but in 60% ethanol extract was shown in a concentration-dependent manner. B16F10 melanoma cell was measured using a powder obtained by lyophilization of 60% ethanol extract. The toxicity was observed at a concentration of $75{\mu}g/mL$. And concentration range was selected to be at most $50{\mu}g/mL$. The effect of tyrosinase, MITF, TRP-1 and TRP-2 on the expression of melanin protein was investigated in melanoma cells of B16F10 melanoma cells. As a result, it was confirmed that as the concentration of the extract increased, the melanogenesis level decreased and the protein expression level also decreased in a concentration dependent manner. Therefore, it was concluded that Matricaria chamomilla L. extract inhibited melanogenesis in cells. Based on the above results, it is expected that it will be used as a useful basic data for industrialization of whitening functional food of Matricaria chamomilla L.

Type 2 diabetes mellitus (T2DM) and its complications are important noncommunicable diseases with high mortality rates. Protein tyrosine phosphatase 1B (PTP1B) and aldose reductase inhibitors are recently approached and advanced for T2DM and its complications therapy. Matricaria chamomilla L. is acknowledged as a worldwide medicinal herb that has many beneficial health effects as well as antidiabetic effects. Our research was designed to determine the most potential antidiabetic phytochemicals from M. chamomilla employing in silico study. 142 phytochemicals were obtained from the databases. The first screening employed iGEMdock and Swiss ADME, involving 93 phytochemicals. Finally, 30 best phytochemicals were docked. Molecular docking and visualization analysis were performed using Avogadro, AutoDock 4.2., and Biovia Discovery Studio 2016. Molecular docking results demonstrate that ligand-protein interaction's binding affinities were -5.16 to -7.54 kcal/mol and -5.30 to -12.10 kcal/mol for PTP1B and aldose reductase protein targets respectively. In silico results demonstrate that M. chamomilla has potential antidiabetic phytochemical compounds for T2DM and its complications. We recommended anthecotulide, quercetin, chlorogenic acid, luteolin, and catechin as antidiabetic agents due to their binding affinities against both PTP1B and aldose reductase protein. Those phytochemicals' significant efficacy and potential as antidiabetic must be investigated in further advanced research.

The essential oil fraction of Chrysanthemum sibiricum Turcz. (Compositae) was analysed by means of TLC and GLC. Utilizing silicagel column chromatography, a blue-color compound was isolated, and purified by preparative TLC. The obtain compound had the same Rf-value on TLC and exactly same UV-visible and IR spectra with that of chamazulene isolated from Matricaria chamomilla L. The composition of the essential oil was also compared with those from flowers of Chrysanthemum indicum L. and Chrysanthemum morifolim Ramatuelia.

The essential oils from whole plant, flower, seed, stem and leaves of domestic chamomile were extracted by simultaneous distillation-extraction and analyzed by GC/ MSD/IRD and retention index matching. The experimental results revealed the presence of over 31 volatile components. Major components were chamazulene, bisabolol, bisabolol oxide A, B. The contents of these major components which possess the pharmacological effects were found to be flower(75.1%), seed(76.6%), stem and leaves(10.09%), whole plant (48.9%), respectively, in domestic chamoile oil, whereas found to be flower(49.2%) in foreign chamomile oil. These results suggest that the usefulness of domestic chamomile is promising because of high contents of these four major components which posses pharmacological effects.

The biological activity of water and ethanol extracts from Chamomaile for functional food source were examined. Total phenol contents in the $60\%$ ethanol extracts $(24.98\pm0.20\;mg/g)$ from Chamomaile leaf was higher than those of water extracts $(23.64\pm0.35\;mg/g)$ The major phenolic compound by HPLC were rosemarinic acid and Quercetin. $60\%$ ethanol extracts had higher content of these phenolics than water extacts. Electron donating ability showed $91.05\%$ in the water extracts and $95.49\%$ in the $60\%$ ethanol extracts. Antioxidant protection factor (PF) showed $0.71\pm0.02 $ in the water extracts and $1.48\pm0.03 $ in the $60\%$ ethanol extracts. The water extracts of Chamomaile leaves did not have antimicrobial activity against H. pylori, but the $60\%$ ethanol extracts revealed the slight antimicrobial activity as 9.42 mm of clear zone. Angiotensin converting enzyme inhibition was $57.98\%$ in water extracts and $91.36\%$ in $60\%$ ethanol extracts. Xanthine oxidase activity was $73.48\%$ in water extracts and $81.96\%$ in $60\%$ ethanol extracts. The results suggest that Chamomailes extract may be useful as potential source as antioxidant, angiotensin converting enzyme and xanthine oxidase inhibitors.
