A new depigmenting-antifungal methylated grindelane from Grindelia chiloensis
(Wiley VCH Verlag, 2017-01)
The new methylated grindelane diterpenoid, 7β‐hydroxy‐8(17)‐dehydrogrindelic acid (1b), together with the known 7α‐hydroxy‐8(17)‐dehydrogrindelic acid (2a), 6‐oxogrindelic acid (3a), 4β‐hydroxy‐6‐oxo‐19‐norgrindelic (4a), ...

Vegetative propagation of Grindelia chiloensis (Asteraceae)
(Elsevier Science, 2000-01)
Grindelia chiloensis (Asteraceae) is a shrub native to Patagonia, Argentina, in the process of domestication as a source of resin to complement rosin production by pines. Vegetative propagation to multiply selected genotypes ...
Karyotypes, heterochromatin distribution and rDNA patterns in South American Grindelia (Asteraceae)
(Taylor & Francis, 2016-12)
Grindelia is a genus with a complex evolutionary history with reticulate evolution. We studied the karyotype, fluorescent banding, and fluorescence in situ hybridization (FISH) using 18–5.8–26 S and 5 S ribosomal DNA probes ...
Allocation of photoassimilates to biomass, resin and carbohydrates in Grindelia chiloensis as affected by light intensity
(Elsevier Science, 2001-03)
Grindelia chiloensis (Asteraceae) is a shrub native to Patagonia, Argentina, and can accumulate as much as 25% resin (on a dry weight basis) in leaves. The resin can be used in applications similar to those of pine resins. ...
Allocation of biomass and photoassimilates in juvenile plants of six Patagonian species in response to five water supply regimes
(Oxford University Press, 2010-08)
Background and Aims The growth-differentiation balance hypothesis (GDBH) states that there is a physiological trade-off between growth and secondary metabolism and predicts a parabolic effect of resource availability (such ...
Activity of grindelanes against important maize pest Spodoptera frugiperda and their selectivity of action on non-target environmental bacteria
(Wiley Blackwell Publishing, Inc, 2021-09)
In the search for new plant-derived products with antifeedant and insecticidal potential against economically important insects, 11 grindelanes (two as natural acids and nine as methylated derivatives) purified from the ...
Effects of phytochemical crusts formed under two desert shrubs on physical properties of soils in arid ecosystems
(Elsevier, 2022-09)
Xerophytic shrubs are usually dominant in arid environments. Because of environmental pressures both biotic and abiotic, many plants have developed a huge diversity of carbon based secondary metabolites (CBSM). Several ...
