Iridoid 배당체 (Ⅳ) : 꽃며느리밥풀의 Iridoid 배당체에 관한 연구
정보섭(B. S. Chung),김영호(Y. H. Kim) 한국생약학회 1982 생약학회지 Vol.13 No.3
Melampyrum roseum Max. is an annual herb in Scrophulariaceae plants. The materials were collected in Kyeongi-Do in 1980. The BuOH extract was evaporated under reduced pressure. The residue was column chromatographed over silica gel with benzene-MeOH (8 : 1) as an eluent and it gave the amorphus powder. Compound I has a molecular formula C_(17)H_(26)O_(10) and it was identified as mussaenoside by chemical data, UV, IR, NMR spectra and compared with the authentic sample of mussaenoside tetraacetate.

Sok-den (Phlomis umbrosa Turcz.) is a perennial herb in Labiatae plants. Shanzhiside methyl ester was isolated from BuOH Ex. of this plant. It was obtained as amorphous powder and its molecular formula is C_(17)H_(26)O<sub>11</sub>. Its structure was determined by chemical reactions an spectral analysis and compared with authentic sample of pentaacetate.
