TAILIEUCHUNG - A new monoaromatic compound from the lichen parmotrema tsavoense (Krog & swinscow) Krog & swinscow (Parmeliaceae)

A new monoaromatic compound, methyl (E)-2,4-dihydroxy-6-methyl-3-(3-oxobut-1-en-1- yl)benzoate (1), together with two common lichen metabolites atranol (2), 2-O-methylatranol (3) were isolated from the lichen Parmotrema tsavoense (Krog & Swinscow) Krog & Swinscow. Their chemical structures were established by 1D NMR, 2D NMR, high resolution ESI–MS spectroscopic analysis and comparison with those reported in the literatures. | TRƯỜNG ĐẠI HỌC SƯ PHẠM TP HỒ CHÍ MINH HO CHI MINH CITY UNIVERSITY OF EDUCATION TẠP CHÍ KHOA HỌC JOURNAL OF SCIENCE KHOA HỌC TỰ NHIÊN VÀ CÔNG NGHỆ NATURAL SCIENCES AND TECHNOLOGY ISSN: 1859-3100 Tập 14, Số 3 (2017): 12-17 Vol. 14, No. 3 (2017): 12-17 Email: tapchikhoahoc@; Website: A NEW MONOAROMATIC COMPOUND FROM THE LICHEN PARMOTREMA TSAVOENSE (KROG & SWINSCOW) KROG & SWINSCOW (PARMELIACEAE) Duong Thuc Huy* Ho Chi Minh City University of Education Received: 23/12/2016; Revised: 28/12/2016; Accepted: 24/3/2017 ABSTRACT A new monoaromatic compound, methyl (E)-2,4-dihydroxy-6-methyl-3-(3-oxobut-1-en-1yl)benzoate (1), together with two common lichen metabolites atranol (2), 2-O-methylatranol (3) were isolated from the lichen Parmotrema tsavoense (Krog & Swinscow) Krog & Swinscow.

TÓM TẮT Một hợp chất đơn vòng mới từ loài địa y Parmotrema tsavoense (Krog & Swinscow) Krog & Swinscow (Parmeliaceae) Một hợp chất đơn vòng mới, methyl (E)-2,4-dihydroxy-6-methyl-3-(3-oxobut-1-en-1yl)benzoate (1), cùng với hai hợp chất địa y phổ biến khác, atranol (2), 2-O-methylatranol (3), đã được cô lập từ loài địa y Parmotrema tsavoense (Krog & Swinscow) Krog & Swincow. Cấu trúc hóa học của chúng được xác định bằng các phương pháp phổ nghiệm cũng như so sánh với các tài liệu tham khảo. Từ khóa: atranol, hợp chất đơn vòng thơm, hợp chất từ địa y, Parmotrema tsavoense. 1. Introduction Our previous phytochemical study on the lichen Parmotrema tsavoense (Duong 2015) led to the isolation of new phenolic compounds such as depsidones and diphenyl Some monoaromatic compounds were also reported from this lichen and these metabolites possess various biological activities such as cytotoxicity, .
