Higher plants can produce a wide variety of anthocyanin molecules through modification of the six common anthocyanin aglycons that they present. Thus, hydrophilic anthocyanin molecules can be formed and stabilized by glycosylation and acylation. Two types of glycosyltransferase (GT) and acyltransferase (AT) have been identified, namely cytoplasmic GT and AT and vacuolar GT and AT. Cytoplasmic G...
Five new diterpenoid alkaloids, ajacisines A–E (1–5), were isolated from Delphinium ajacis, along with seven known alkaloids (6–12). On the basis of their spectral data (IR, UV, HR‐ESI‐MS, 1D and 2D NMR) and chemical properties, the structures of compounds 1–12 were identified. All isolated compounds were evaluated for their in vitro antiviral activities against respiratory syncytial virus, and...
Background and purpose: Herbal drug derivatives have been commonly used in management and treatment and of some infections. This study aimed at evaluating the antibacterial effects of Chondrilla juncea L, Ajuga comata Stapf, Nepeta ucrainica L, and Delphinium speciosum M.B extracts. Materials and methods: Antibacterial activity of different extracts (n-hexane, dichloromethane, and methanol) o...
Toxic plants such as Delphinium spp. (i.e., larkspur) are a significant cause of livestock losses worldwide. Correctly determining the causative agent responsible for the death of an animal, whether by disease, poisonous plant, or other means, is critical in developing strategies to prevent future losses. The objective of this study was to develop an alternative diagnostic tool to microscopy an...
Four new diterpenoid alkaloids: tiantaishansine (1), tiantaishannine (2), tiantaishanmine (3), and tiantaishandine (4) have been isolated from the roots of Delphinium tiantaishan. Their structures were elucidated by chemical evidence and spectral analyses, including ESI-MS, HR-EI-MS, 1D- and 2D-NMR.
* The carbon costs of reproduction were examined in four subalpine herbaceous plant species for which number and size of flowers respond differently under a long-term infrared warming experiment. * Instantaneous measurements of gas exchange and an integrative model were used to calculate whole-plant carbon budgets and reproductive effort (RE). * Of the two species for which flowering was reduce...
در راستای بازنگری نمونه‌های هرباریومی متعلق به جنس Delphinium، گونه D. kurdicum Boiss. & Hohen. برای اولین بار از غرب ایران گزارش می‌گردد. همچنین، گونه D. zalil Aitch & Hemsl. به عنوان یک گونه مستقل از D. semibarbatum Bienert ex Boiss. معرفی شده است. این گونه با گونه مجاور خود D. ochrolecum Stev. ex DC. مقایسه شده است. این گونه‌ها براساس ویژگی‌های مورفولوژیکی، گرده‌شناسی و الگوی اپیدرمی گلپوش ...
