TL;DR: This work identified and confirmed additional target genes of the R2R3-MYB subgroup 7 factors, including the UDP-glycosyltransferases UGT91A1 and UGT84A1, and demonstrated that the accumulation of distinct and structurally identified flavonol glycosides in seedlings correlates with the expression domains of the different R2r3- MYB factors.
Journal ArticleDOI
Quality control of herbal medicines
TL;DR: Several novel chemometric methods for evaluating the fingerprints of herbal products, such as the method based on information theory, similarity estimation, chemical pattern recognition, spectral correlative chromatogram (SCC), multivariate resolution, etc, are discussed in detail with examples, which showed that the combination of chromatographic fingerprints and the chemometric evaluation might be a powerful tool for quality control of herbal medicines.
Journal ArticleDOI
Chemical analysis of Ginkgo biloba leaves and extracts.
TL;DR: The chemical analysis and quality control of Ginkgo leaves and extracts is reviewed in this paper, where the terpene trilactones are extracted with aqueous acetone and supercritical fluid extraction.
Journal ArticleDOI
Antibacterial and phytochemical screening of Anethum graveolens, Foeniculum vulgare and Trachyspermum ammi
Gurinder Kaur,Daljit Singh Arora +1 more
TL;DR: Antibacterial efficacy shown by these plants provides a scientific basis and thus, validates their traditional uses as homemade remedies, and proves the better/equal efficacy of some of these seed extracts as compared to standard antibiotics.
Journal ArticleDOI
Preliminary comparative analysis of medicinal plants used in the traditional medicine of Bulgaria and Italy.
TL;DR: From this comparison it emerges that knowledge of medicinal plants and their uses are well founded, more than 80% of the plants are employed in identical or similar kinds of ailments, their preparation also showing marked similarities.
