Abstract
Macrophyllidimer C, a novel bis-sesquiterpene, in which the two sesquiterpene units are directly connected by a C-C bond, and eight other sesquiterpenolides were obtained from the bark of Inula macrophylla. Seven of these, macrophyllilactones A-G, are new eudesmanolide- and elemanolide-type sesquiterpenes. Their structures were determined on the basis of spectroscopic evidence and chemical reaction.

Abstract
Ethyl acetate extracts of the air-dried fruits of Ferula kuhistanica afforded three daucane esters: kuhistanicaol H, I and J, together with nine other known compounds. Their structures were established on the basis of spectroscopic evidence. Isolated compounds in this paper and previously reported compounds from the roots and stems of F. kuhistanica were tested for antibacterial activity. Some of them were selectively toxic against Gram-positive bacteria, including methicillin-sensitive and methicillin-resistant Staphylococcus aureus (MSSA and MRSA).

Abstract
The methanol extract of the dried aerial parts of Prangos tschimganica gave three new coumarin derivatives and 30 known coumarin derivatives. Their structures were established on the basis of chemical and spectroscopic evidence. Absolute configuration of the isolated compounds were determined by using a modified Mosher's method. Some of the isolated compounds showed anti-HIV activity.

Abstract
Eleven new sesquiterpenes (1--11) and two thymol derivatives (12, 13), along with 12 known sesquiterpenes and monoterpenes, were isolated from the bark of Inula macrophylla. Their structures were determined on the basis of spectral evidence (especially by HREIMS and 2D NMR) as well as chemical transformations. The structure of macrophyllic acid A (1) was confirmed by X-ray analysis, and the absolute configuration of 1 was determined on the basis of the appropriate chemical conversions and the application of a modified Mosher's method.

Abstract
Six new compounds-two sesquiterpene coumarins, pallidones A and B (1, 2), and four related derivatives, pallidones C-F (3-6), as well as two known sesquiterpene coumarins, feselol (7) and conferol (8), have been isolated from the EtOAc extracts of the roots of Ferula pallida. All structures of these compounds were determined on the basis of spectral evidence, especially 2D NMR ((1)H-(1)H COSY, HSQC, HMBC, and NOESY) and HRMS. The possible biosynthetic pathway of pallidones C-F (3-6) is discussed.
