“…The principal classes of organic compounds in the aerial essential oil were polar and non-polar organic compounds. The chemical composition of this aerial essential oil is different from those reported in other studies for some related species such as those reported for L. tomentosa 42 , L. decurrens 43 , L. aurita 44,45 , L. alata 46 and L. pterodonta 47,48 .…”

“…Meanwhile, Bacillus sp and S. dysenteriae were resistance at this concentration of the essential oil. Comparatively, the essential oil investigated in this study showed a promising antibacterial potential than the previously studied species such as Laggera tomentosa where S. aureus and B. cereus showed very low zone of inhibition and E. coli and K. pneumonia showed resistance to the essential oil 54 . The tested bacteria were found to be sensitive to gentamicin (GEN) synthetic antibiotics.…”

This study was undertaken to provide more scientific information about the phytochemical composition of Laggera crispata known for its medicinal uses. Essential oil was isolated by hydro-distillation, analysed using GC-MS, UV-Visible Spectrophotometer and other established biochemical assays were used for the study. The GC-MS analysis of the aerial essential oil of L. crispata showed the presence of 35 medicinal organic compounds making up 84.4% of the oil. The most abundant component was a phenolic compound called 2-tert-Butyl-1,4-dimethoxybenzene (54.5%). The other major terpenoids present in the oil were α-humulene (6.9%) and (+)-sabinene (5.9%). The TPC, TFC, TAA and TAC values of the aerial essential oil of L. crispata were 172.75±0.00 µgmg -1 GAE, 48.69±0.00 µgmg -1 QE, 61.85±0.00 µgmg -1 AAE and 726.92±0.00 µgmg -1 AAE respectively. DPPH IC 50 and AAI values of the essential oil were 1.5 µgml -1 and 26.7. The essential oil displayed varying inhibitory activities against Gram-positive and Gram-negative bacteria with zones of inhibition ranging from 08-30 mm. The in vitro pharmacological activities added scientific support to the use of L. crispata in alternative and complementary medicine. The essential oil of L. crispata grown in Nigeria will play beneficial roles in human and animal health and therefore a research on this plant might be of great value in drug industries.

“…It is worth to note that the activity of C. cernuum APEO against the standard line of E. coli is equal to that against S. aureus, a Gram-positive bacterium. C. cernuum REO was less active against E. coli which conforms to literature data on antibacterial activity of 2,5-dimethoxy- p -cymene-rich essential oils [ 29 , 40 ]. That activity is usually less pronounced against Gram-negative bacteria.…”

Carpesium cernuum L., one of the two Carpesium species occurring in Europe, in the Far East and India, found use as a vegetable and a traditional medicinal remedy for several ailments. In the present study, compositions of essential oils distilled from roots and shoots of C. cernuum plants, cultivated in the open field, have been studied by GC-MS-FID supported by NMR spectroscopy. The analyses led to the identification of 120 compounds in total, of which 115 were found in aerial parts and 37 in roots of the plants. The major constituents found in the oil from shoots were: α-pinene (35%) and 2,5-dimethoxy-p-cymene (thymohydroquinone dimethyl ether, 12%), whereas 2,5-dimethoxy-p-cymene (55%), thymyl isobutyrate (9%) and thymol methyl ether (8%) predominated in the essential oil obtained from the roots. Antibacterial and cytotoxic activities of the essential oils distilled from C. cernuum were also tested. The essential oil from aerial parts of the plant demonstrated good inhibitory activity against Staphylococcus aureus ATCC 29213 and Escherichia coli ATCC 25922 (MIC: 15.6 μL/mL).

“…& Hiern is frequently being used by the healers to treat tonsils and headache in and around Gullele Botanical Garden. The antioxidant and the bactericidal activities of the essential oil of this plant have been documented ( Getahun et al, 2020 ). The dominant compound in the essential oil of this plant are oxygenated monoterpenes and thymol methyl ether ( Asfaw et al, 2003 ).…”

Ethnobotanical study of endemic and non-endemic medicinal plants used by indigenous people in environs of Gullele botanical garden Addis Ababa, central Ethiopia: A major focus on Asteraceae family

et al. 2022

Gullele Botanical Garden (GBG) in Addis Ababa, Ethiopia is a joint venture of Addis Ababa government and the university. The garden has been built mainly to conserve the endemic plants and to advance the research on the endemic and non-endemic plants collected from different part of Ethiopia. Many traditional healers from the environs of GBG and different subcities of Addis Ababa depend on the garden for their practice of traditional medicine but there is no systematic documentation of the traditional medicinal knowledge of these healers. The main objective of the present study is to comprehensively document the ethnobotanical and ethnomedicinal information from the traditional healers of different ethnic and cultural groups depending on GBG and to create a database of the endemic plants used by these healers. The ethnobotanical and ethnomedicinal data obtained from 60 traditional healers have been analyzed both qualitatively and quantitatively. A total of 81 medicinal plants belonging to 47 families have been identified. Majority of the plants used belonged to Asteraceae (12) family. The most frequently used plant form and plant parts are herbs and leaves. The major method adopted by the healers for preparation and administration of traditional medicine is crushing and topical, respectively. Skin and general diseases are the most important ailments treated by the healers. The three most cited plants used to treat diseases are Echinops kebericho Mesfin (60), Hagenia abyssinica (Bruce) J.F.Gmel (60) and Laggera tomentosa (A.Rich.) Sch.Bip. ex Oliv. & Hiern (58). The present study is the first systematic, qualitative, and quantitative ethnobotanical analysis and documentation done on the use of the medicinal plants from GBG for traditional medicine. In addition, our study reveals that E. kebericho is endemic and endangered plant and is highly used in traditional medicine. Therefore, GBG authorities should take steps for the propagation and restoration of this plant. Further it is suggested that the pharmacological properties of the roots and leaves of E. kebericho should be compared to find the possibility of use of leaves in place of roots for the preparation of traditional medicine which would help in conserving this endemic plant of Ethiopia.
