  Diastereomers of lithospermic acid and lithospermic acid B from Monarda fistulosa and Lithospermum erythrorhizon

  摘要：

  Monardic acids A (1) and B (2), which are (7R,8R) diastereomers of lithospermic acid (LA) and lithospermic acid B, respectively, were isolated from Monarda fistulosa. A (75,8R) isomer (3) of LA was also isolated from this plant, and a (7R,8S) isomer (7) of LA was obtained from Lithospermum erythrorhizon. The absolute configuration of 1 was confirmed by analysis of its hydrolysates, 7-epiblechnic acid and 2R-3-(3,4-dihydroxyphenyl)-2-hydroxypropanoic acid. The configuration in the dihydrobenzofuran moieties of 2, 3, and 7 was extrapolated by using the phenylglycine methyl ester method and a Cotton effect at approximately 250-260 nm in their electronic circular dichroism spectra. Diastereomers (1-3 and 7) displayed moderate hyaluronidase inhibitory and histamine release inhibitory activities. (C) 2013 Elsevier B.V. All rights reserved.

  An extract of Keiskea japonica MIQ. showed an inhibitory effect on hyaluronidase activity. From the extract, four new phenylpropanoids, two new maltol glycosides, two new monoterpene glycosides, and two new phenolic compounds were isolated together with 19 known compounds. Among these constituents, two phenylpropanoids and a flavone glucuronide were revealed as hyaluronidase inhibitors.

  Eight new caffeic acid oligomers, clinopodic acids J–Q (1–8), were isolated from whole plants of Clinopodium gracile, together with nine known caffeic acid oligomers. The caffeic acid oligomers with two to four dihydrobenzofuran rings were isolated as natural products for the first time. Clinopodic acid M (4) showed the strongest hyaluronidase inhibitory activity, IC50 (19 µM) among the 22 compounds isolated from this plant.

  The new benzofuran lignans nepetamultin A (1) and B (2) were isolated from flowers of Nepeta multifida L. [Schizonepeta multifida (L.) Briq.; Lamiaceae]. UV and NMR spectroscopic and mass spectrometric data indicated 1 was the 9′9′′′-di-O-methyl ester of schizotenuin A; 2, the 9′-O-methyl ester of schizotenuin C1. Biological studies revealed that 1 and 2 possessed antioxidant and antihyaluronidase activity.

  Takuran is a traditional herbal medicine that is produced from the herbal plant Lycopus lucidas TURCZ. (Lamiaceae). Takuran is used as a treatment for diseases in women. From Takuran, four new phenylpropanoids along with 18 known compounds were isolated, and their structures were elucidated by spectroscopic analyses. Five phenylpropanoids isolated from the plant showed hyaluronidase inhibitory activity comparable to that of rosmarinic acid.
