HPLC screening of pentacyclic triterpenoids (oleanolic and ursolic acids) in raw materials of ten Epilobium species (Epilobium parviflorum Schreb., Epilobium hirsutum L., Epilobium montanum L., Epilobium collinum C. C. Gmel., Epilobium roseum Schreb, Epilobium palustre L., Epilobium tetragonum L., Epilobium obscurum Schreb, Epilobium nervosum Boiss. & Buhse, Epilobium nutans F. W. Schmidt) from Ukraine were carried out. The absence of studied triterpenoids delimits E. parviflorum and E. hirsutum from other species. This distinction is not connected to climatic factors since the samples from different collection sites were tested for both species. The triterpenoid presence/absence criteria might be one of the marker in chemotaxonomic study of genus Epilobium. In the aerial part of other eight studied species ursolic acid was contained in moderate quantity (20.27±0.49 mg/100g -74.84±2.24 mg/100g) and dominated the oleanolic acid (2.03±0,05 – 32.09±0.73 mg/100g). Aerial part of E. roseum had a lowest ursolic acid content (20.27±0.49 mg/100g) and oleanolic acid was not detected in this sample. Both identified triterpenoids can contribute to anti-proliferative effect of ethanolic and nonpolar extracts of Epilobium herbs on prostate cancer cells.
Now we closed the publication phase and launched the post-publication phase of the conference. REVIEWWWERS'08 Brainstorming Workshop is Now Open from 2023-Jan-01 to 2023-Jan-31. MOL2NET Committee, Authors, and Validated Social Media Followers Worldwide are invited to Post Moderated Questions/Answers, Comments, about papers. Please kindly post your public Answers (A) to the following questions in order to promote interchange of scientific ideas.
My Question (Q) to you:
Q1. What are the future applications of your discovery?
Q2. You stated that Aerial part of E. roseum had a lowest ursolic acid content. Is there any positive conclusion with regards of this result?
Dear author thanks in advance for your kind support answering the questions.
Now, the conference publication phase is close but you can answer here directly as a post-publication comment. However, in case you want to elaborate your answers in a more structured way in the form of a short communication we can upload it free-of-cost on your behalf to the CATCHTOHIT-03: Congress on Acad. Transl. Res. for Companies Helping to Height. Innov. & Tech., Bilbao-Cambridge, MA, USA, 2022. https://mol2net-08.sciforum.net/catchtohit-03
