“…Although chemical and pharmacological interest in the genus Clinanthus has increased in recent years, only seven published articles about this genus can be found in the literature, and five of them correspond to the description of new species [ 1 , 9 , 10 , 21 , 22 ]. The first report of a chemical characterization and bioactivity evaluation of a species from this genus was carried out by Adessi and co-workers [ 23 ], who reported the inhibition of AChE and BChE enzymes by the alkaloid 6-hydroxymaritidine, extracted and purified from C. microstephium [ 23 ].…”

The genus Clinanthus Herb. is found in the Andes Region (South America), mainly in Peru, Ecuador, and Bolivia. These plants belong to the Amaryllidaceae family, specifically the Amaryllidoideae subfamily, which presents an exclusive group of alkaloids known as Amaryllidaceae alkaloids that show important structural diversity and pharmacological properties. It is possible to find some publications in the literature regarding the botanical aspects of Clinanthus species, although there is little information available about their chemical and biological activities. The aim of this work was to obtain the alkaloid profile and the anti-cholinesterase activity of four different samples of Clinanthus collected in South America: Clinanthus sp., Clinanthus incarnatus, and Clinanthus variegatus. The alkaloid extract of each sample was analyzed by gas chromatography coupled with mass spectrometry (GC-MS), and their potential against the enzymes acetyl- and butyrylcholinesterase were evaluated. Thirteen alkaloids have been identified among these species, while six unidentified structures have also been detected in these plants. The alkaloid extract of the C. variegatus samples showed the highest structural diversity as well as the best activity against AChE, which was likely due to the presence of the alkaloid sanguinine. The results suggest this genus as a possible interesting new source of Amaryllidaceae alkaloids, which could contribute to the development of new medicines.

Clinanthus inflatus (Amaryllidaceae) and Ismene parviflora are described from Ancash Department in Peru. The flower of C. inflatus is urceolate, and resembles that of Urceolina (Amaryllidaceae tr. Eucharideae), a unique morphology for the genus. Ismene parviflora, with its small, loosely formed, narrowly funnelform-tubular perigone with a ventricose limb, appears to have some affinity to subgen. Pseudostenomesson and may represent an intermediate form between the former and species of subgen. Ismene. Stenomesson rubrum is transferred to Clinanthus as C. ruber on the basis of its narrowly lorate leaf morphology.

“…The new species described in this paper is the third species of the genus and the first record from Colombia. It is also the first species of the tribe Clinantheae, to which Pamianthe has been assigned (Meerow et al 2000; Leiva and Meerow 2016), discovered north of Ecuador.…”

A new saxicolous species of Amaryllidaceae tentatively assigned to the tribe Clinantheae, Pamiantheecollis Silverst., Meerow & Sánchez-Taborda, is described from the western slope of the Cordillera Occidental in the department of Cauca, Colombia. The new species differs from the two hitherto known species of Pamianthe in its yellow flowers and in its nearly obsolete perianth tube. The near loss of the perianth tube may be correlated with a change in pollinator. The new species lacks a bulb; it produces a large number of winged seeds that are wind-dispersed. A key to the species of Pamianthe is provided. This is the first record of the genus Pamianthe for Colombia. The phylogenetic position of the genus Pamianthe is discussed.
