officinale, the volatile chemical constituents of these umbelliferous medicinal plants were compared with GC-MS. To identify oviposition inhibitors for P. Schmidt ex Miquel were the most numerous, those on Saposhnikovia divaricata Schischkin and Cnidium officinale Makino were rare, and Bupleurum falcatum Linné was not oviposited at all.
machaon on six umbelliferous medicinal plants, the eggs on A.
When we compared the numbers of eggs laid by P. The most serious problem in the cultivation of umbelliferous medicinal plants is the feeding damage caused by the common yellow swallowtail (Papilio machaon hippocrates C. Umbelliferous medicinal plants, such as Angelica acutiloba Kitagawa and Angelica dahurica Bentham et Hooker filius ex Franchet et Savatier, account for a large percentage of crude drug consumption in Japan.

Conclusions The UPLC-QTOFMS based metabolomics approach has great potential for analysis of the alterations of secondary metabolites of Angelica sinensis during growth. The study has shown that accumulation of secondary metabolites of Angelica sinensis is closely related to the growth periods. These markers were further verified by accurate mass tandem mass and retention times of available reference standards. The chemical markers accounting for these separations were identified from the PCA loadings plot. Results Principal component analysis of the UPLC-QTOFMS data showed that these 27 samples could be separated into 4 different groups. Metabolic fingerprinting of Angelica sinensis during growth using UPLC-TOFMS and chemometrics data analysisīackground The radix of Angelica sinensis is widely used as a medicinal herbal and metabolomics research of this plant during growth is necessary. Keeping a certain value for the volume of the silver nanoparticles, the fluorescence intensity at 402 nm was linearly proportional to the Angelica in the range of 1-3 mg/mL. We also observed fluorescence quenching of the Angelica solution in the presence of spherical silver nanoparticles with radius of 12 nm. Through fluorescence spectra of Angelica solution under different pH values, results indicated coumarin compounds were the active ingredients of Angelica. Zhao, Hongyan Song, Feng Liu, Shujing Chen, Guiyang Wei, Chen Liu, Yanling Liu, Jiadongīy measuring the fluorescence spectra of Chinese medicine (CM) Angelica water solutions with different concentrations from 0.025 to 2.5 mg/mL, results showed that the fluorescence intensity was proportional to the concentration. A fluorescence spectroscopy study of traditional Chinese medicine Angelica
