[Study on the chemical constituents from ethyl acetate extract of Micromelum falcatum].Zhong Yao Cai. 2013 May; 36(5):744-6.ZY
To study the chemical constituents from ethyl acetate extract of Micromelum falcatum.
The constituents were separated and purified by silica gel, Sephadex LH-20 and HPLC. Their structures were elucidated by spectral analysis (NMR, MS).
Ten compounds were isolated and identified as micropubescin (1), phebalosin (2), scopoletin (3), citrubuntin (4), thamnosmonin (5), hopeyhopin (6), arnottinin (7), casegravol (8), 2-methoxy-5-hydroxy cinnamate (9), threo-syringoylglycerol (10).
Compounds 1 - 10 are obtained from this plant for the first time.
