Later, this compound was also reported from the fungal genera, Diplodia, Pestalotia and Pestalotiopsis. Oxysporone was patented as an antibiotic for the treatment of dysentery, and its phytotoxic property has been well-established. Interesting biological and chemical properties of oxysporone make this compound attractive for its potential biotechnological applications in agriculture, especially as a new agrochemical with a lower environmental impact. However, it requires further extensive bioactivity screening looking at beyond its established phytotoxicity and preliminary antifungal property. It has a simple chemical structure (C₇H₈O₄), and the hydroxyl group at C-4 provides options for synthesising numerous analogues by simply incorporating various functionalities at C-4, whilst keeping the main skeleton intact. This mini-review provides a critical overview on the occurrence, production, synthesis, structure elucidation and bioactivities of oxysporone. تفاصيل المقالة -

Because of the unique chemical diversity offered by plants, it is often a tedious and complicated process when it comes to structure elucidation of phytochemicals. Recent advances in spectroscopic techniques, particularly in NMR and MS methodologies, have provided various tools that assist phytochemists with the structure elucidation of known or new phytochemicals. However, spectroscopic data interpretation manually requires significant experience and expertise, knowledge, intellectual ability and patience; often the manual process can be quite time consuming and even be frustrating. Over the last several decades, especially with the phenomenal progress in computation and applications of artificial intelligence and various mathematical modelling, several automated spectral data interpretation and structure elucidation software have become available to the phytochemists. These automated tools, not necessarily have replaced human intelligence or efforts, but certainly have facilitated the process, and improved the accuracy of structure elucidation of phytochemicals. تفاصيل المقالة -

While أکثرCentaurea asutro-anatolica Hub.-Mor. and C. kizildaghensis Uzunh., E. Doğan & H. Duman, two indigenous perennial herbs from the Turkish flora, belong to the medicinally important genus Centaurea L. (fam: Asteraceae), which comprises ca. 600 species worldwide. While various Centaurea species are well-known for producing alkaloids, flavonoids, lignans and terpenoids, there is no report on any thorough phytochemical work on any of these two species available to date. In continuation of our phytochemical and bioactivity studies on the Turkish Centaurea species, four flavonoids apigenin (1), apigenin 7,4’-dimethyl ether (2), genkwanin (3) and quercetin (4) were isolated from the methanol extracts of the aerial parts of C. austro-anatolica and C. kizildaghensis, for the very first time. The structures of the flavonoids were elucidated conclusively by spectroscopic means, i.e., UV, MS and 1D and 2D NMR data analyses. The distribution of these flavonoids (1-4) within the genus Centaurea and their possible chemotaxonomic implications within the genus Centaurea or the family Asteraceae have been discussed. تفاصيل المقالة
