Cubeb (Piper cubeba)

Kemukus or tailed pepper or cubeb (Piper cubeba) is a species of plant in the Piperaceae, growing climbing, woody perennial and sturdy, up to 10 meters or more high on supporting trees, spreading, rooting easily where the stems are left touching the ground.

P. cubeba has leaves that sit alternately, intact, thick, 5-10 cm long, 2-6 cm wide and green. Flowers are small, produced on pendulous spikes 4-8 cm long at leaf nodes, spikes extending to 7-15 cm as fruit ripens. The fruit is round, has a long stalk, is green and turns brownish red.

Cubeb (Piper cubeba)


This species grows in moist, well-drained, organic matter-rich areas, elevations below 900 meters and climbs trees with rough bark. The plants bear fruit from the fourth or fifth year and usually for seven years. One stem produces 20-30 spikes of fruit.

The fruit is carefully dried as a dried berry, similar to black pepper, but with the stem attached. The dry pericarp is wrinkled and grayish brown to black in color. The seeds are hard, white and oily. The dried fruit is aromatic and has a pungent, tangy, slightly bitter and persistent taste.





Dried fruit is processed into essential oil. Dried fruit contains essential oils consisting of monoterpenes (50% sabinene, α-thujene, and carene) and sesquiterpenes (caryophyllene, copaene, α- and β-cubebene, δ-cadinene, germacrene), oxides 1,4- and 1, 8-cineole and a cube of alcohol.

About 15% essential oil is obtained by distilling the fruit with water. Cubebene, the liquid part, has the formula C15H24 and is available in two forms, α- and β-. They differ only in the position of the alkene moiety, with the double bond being endocyclic in the α-cubeben, as shown, but exocyclic in the β-cubeben. It is a thick, pale green liquid with a warm woody, slightly camphoraceous odor. After being fixed with water or stored, it precipitates rhombic crystals of camphor.

Cubebin (C20H20O6) is a crystalline substance found in fruit. It can be made from cubebene or from the dregs left after oil refining. The drug, along with gum, fatty oils, and malate of magnesium and calcium, also contains about 1% cubic acid, and about 6% resin.

These herbs are used in treating gonorrhea, where its antiseptic action is invaluable. flavoring agent for gin, smoking blends, incense blends and food seasonings. The fruit is used to add flavor to savory soups and curries and pastries.

A deep-sea isopod Bathyopsurus nybelini adapted to feed submerged Sargassum algae

NEWS - Incredible footage shows a marine species, Bathyopsurus nybelini , feeding on something that sinks from the ocean’s surface. Researchers using the submersible Alvin found the isopod swimming 3.7 miles down using its paddle-like legs to catch an unexpected food source: Sargassum. Researchers from Woods Hole Oceanographic Institution (WHOI), the University of Montana, SUNY Geneseo, Willamette University and the University of Rhode Island found the algae sinking, while the isopod waited and adapted specifically to find and feed on the sinking nutrient source. The Sargassum lives on the surface for photosynthesis. The discovery of a deep-sea animal that relies on food that sinks from the waters miles above underscores the close relationship between the surface and the deep. “It’s fascinating to see this beautiful animal actively interacting with sargassum, so deep in the ocean. This isopod is extremely rare; only a handful of specimens were collected during the groundbreaking Swedis

Ngamugawi wirnagarri reveals evolution of coelacanth fish and history of life on earth

NEWS - An ancient Devonian coelacanth has been remarkably well preserved in a remote location in Western Australia linked to increased tectonic activity. An international team of researchers analysed fossils of the primitive fish from the Gogo Formation of Ngamugawi wirngarri , which straddles a key transition period in the history of coelacanths, between the most primitive and more modern forms. The new fish species adds to the evidence for Earth’s evolutionary journey. Climate change, asteroid strikes and plate tectonics are all key subjects in the origins and extinctions of animals that played a major role in evolution. Is the world’s oldest ‘living fossil’ the coelacanth still evolving? “We found that plate tectonic activity had a major influence on the rate of coelacanth evolution. New species are more likely to have evolved during periods of increased tectonic activity when new habitats were divided and created,” says Alice Clement of Flinders University in Adelaide. The Late Dev

Species going extinct every day and without warning

NEWS - The current rate of human-caused extinction is up to 700 times higher than it was in the past. Extinctions are no different for plants, animals and fungi, although the extinctions of botanicals and invertebrates have been far worse than those of vertebrates. The mass extinctions increased from 1890 to 1940, but a decline in extinctions was only recorded after the 1980s, likely due to taxonomic bottlenecks and the pre-1800 extinction rates being affected by a lack of data. The number of species varies from 2-8 million to 1 trillion, and estimates suggest that most species, especially microbes and fungi that may be key to healthy ecosystems, are still undiscovered. The biodiversity crisis is therefore extremely difficult to measure. “If we don’t know what we have, it’s impossible to measure how much we’re losing. This taxonomic gap urgently needs to be addressed,” say Maarten Christenhusz and Rafaël Govaerts of the Royal Botanic Gardens, Kew. Yet taxonomy is in decline. Misunderst
