The most common compounds found in Radula species are 3,5-dihydroxy-2-(3-methyl-2-butenyl)bibenzyl and 2-geranyl-3,5-dihydroxybibenzyl, which often form the basic structure for more complex molecules in these plants. [17] Of particular interest is the presence of compounds similar to those found in cannabis (cannabinoids) in some Radula species
For nearly 200 years, Radula remained the only genus in the family, making Radulaceae a monogeneric family within the order Porellales. [7] Herbert Castle's 1936 worldwide monograph of Radula took a broader view of Cladoradula, expanding it to include all species with reproductive structures on short branches, regardless of other features. This ...
The radula (US: / ˈ r æ dʒ ʊ l ə /; pl.: radulae or radulas) [1] is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. [2] It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus .
Perrottetinene is a naturally occurring cannabinoid compound found in liverworts from the family Radulaceae native to Japan, New Zealand and Costa Rica, namely Cladoradula perrottetii, Radula marginata and Radula laxiramea, [1] [2] along with a number of similar compounds.
Cladoradula perrottetii is a species of liverwort is the family Radulaceae. [2] It is distributed across tropical and subtropical Southeast Asia, occurring in Thailand, Sumatra, Taiwan and Japan. It contains the small molecule perrottetinene, a cannabinoid, [3] [4] and other secondary metabolites of scientific interest including marchantin A. [5]
Individual shoots are typically 0.3–1.5 mm (0.012–0.059 in) wide and can reach up to 20 mm (0.79 in) in length. The plant has two distinct parts to each leaf: a larger upper lobe (dorsal lobe) and a smaller lower lobe (ventral lobe), which is a characteristic feature of the genus Radula. [3]
Melaleuca radula is a spreading shrub, growing to 5 m (20 ft) tall with coarse bark. Its leaves are arranged in alternating pairs ( decussate ) so that they make four rows along the branches. The leaves are 10–45 mm (0.4–2 in) long, 0.7–2 mm (0.03–0.08 in) wide, linear to elliptic in shape with the sides turned up so that they are ...
