Isopimarane diterpenoids from the aerial parts of Hymenocrater elegans with anti-inflammatory potential.
Eight previously undescribed and one fully characterized isopimarane diterpenoids, hymenocraterol (A-I), were isolated from n-hexane extract of the aerial parts of Hymenocrater elegans. Their structures were elucidated using HRMS, 1D and 2D-NMR, and electronic circular dichroism calculation techniques. Hymenocrater spe...
