TL;DR: Twenty-two populations of seven species of Cremanthodium from high altitude regions of western China were observed karyologically, and two basic chromosome numbers correspond exactly to two branching patterns in this genus, sympodial versus monopodial.

TL;DR: Two samples of Cremanthodium stenactinium (Asteraceae) were collected in Sichuan Province, China and from the ethyl acetate extracts of the roots, three new eremophilane-type sesquiterpenoids and one new trinoreremophILane compound were isolated, together with other known eRemophilanes.
Abstract: Two samples of Cremanthodium stenactinium (Asteraceae) were collected in Sichuan Province, China. From the ethyl acetate extracts of the roots, three new eremophilane-type sesquiterpenoids and one new trinoreremophilane compound were isolated, together with other known eremophilanes. Their structures were determined based on the spectroscopic data. This is the first report of isolation of eremophilane-type compounds from the genus Cremanthodium.

TL;DR: The results suggest that nodding capitula in C. campanulatum possibly confer a selective advantage and may be driven by non-biological agents rather than pollinator attractors.
Abstract: Background: Flower orientation is considered an evolutionary response to pollinators and abiotic factors. Several members of the genus Cremanthodium (Asteraceae) growing in alpine habitats in the Sino-Himalayas have conspicuously nodding capitula, the function of which is not understood.

TL;DR: Four new eremophilane-type sesquiterpenoid alcohols were isolated from Cremanthodium helianthus collected in China and their structures established on the basis of spectroscopic analyses.
Abstract: Four new eremophilane-type sesquiterpenoid alcohols were isolated from Cremanthodium helianthus collected in China and their structures established on the basis of spectroscopic analyses. All of them had 9-en-8-one partial structures with one more double bond either Delta(11), Delta(11(13)), or Delta(7(11)). Two of them had a hydroxy group at C-1 position.
