“…Many farm lands, pasture fields and forests have been destroyed, causing huge economic losses. This has been drawn to the attention of the society and many methods have been developed to control it, such as manual, chemical and biological means, however without any realistic means to eradicate it [2,3]. There is a large amount of E. adenophorum in Yunnan Province of China -more than 12,000,000 tons.…”

The present study attempts to utilize Eupatorium adenophorum to prepare high surface area activated carbon (HSAAC) with K 2 CO 3 activation using microwave heating. The operational variables including microwave power, K 2 CO 3 /C mass ratio and heating time on the adsorption capability and yield were identified. Additionally, the surface characteristics of HSAAC were characterized by nitrogen adsorption isotherms, X-ray diffraction, Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The optimum conditions resulted in HSAAC with an iodine number of 1696 mg/g and a yield of 32.88%. The Brunauer-Emmett-Teller (BET) surface area and total volume were 2768 m 2 /g and 1.149 ml/g, respectively. The findings strongly support the feasibility for preparation of HSAAC from E. adenophorum by microwave heating.

“…The earlier investigation of the essential oil of E. adenophorum leaves from India shows 1-napthalenol (17.50%), α-bisabolol (9.53%), bornyl acetate (8.98%), β-bisabolene (6.16%), germacrene-D (5.74%) , α-phellandrene (3.85%) and a di-epi-α-cedrene (2.98%) 12 . Weyerstahl and co-workers from India (1997) reported the composition of the essential oil of flowers of E. adenophorum 22 . The major constituents were α-phellandrene (15.3%), camphene (12.2%), bornyl acetate (10.6%), p-cymene (8.5%), γ-curcumene (4.5%) and 2-carene.…”

The essential oil of Ageratina adenophora locally call Banmara was analyzed by GC-MS. A total of 45 volatile compounds was identified and torreyol (16.8%) was the major component in oil. The sesquiterpene fraction was higher than the monoterpene one. The essential oil showed significant antibacterial activity against both gram positive (Klebsiella pneumoniae and Staphylococcus aureus) and gram negative (Escherichia coli and Proteus vulgaris) bacteria.

“…[6] E. adenophorum is reported to contain an array of bioactive constituents like monoterpenes, sesquiterpenes, flavonoids, phenyl propanoids and their derivatives. [7][8][9] It is also known for its insect control properties. [10][11][12][13][14] Solvent concentrate of leaves and flowers are mainly consisted with sesquiterpenoid derivatives.…”

Bioactive constituents of Eupatorium adenophorum were investigated for antifungal activity. A structure-antifungal activity relationship of cadinene sesquiterpenes was predicted by evaluating individual derivatives. Cadinene derivatives were extracted from leaves of Eupatorium adenophorum using ethyl acetate. Five cadinene sesquiterpenes were isolated by column chromatography and Preparative Thin Layer Chromatography. Bioactivity of these cadinene sesquiterpenes were evaluated in vitro against four phytopathogenic fungi using poison food technique. Purified sesquiterpenes were spectroscopically elucidated as cadinan-3-ene-2,7-dione (1), 7-hydroxycadinan-3-ene-2-one (2), 5,6-dihydroxycadinan-3-ene-2,7-dione (3), cadinan-3,6-diene-2,7-dione (4) and 2-acetyl-cadinan-3,6-diene-7-one (5). Antifungal evaluation of these compounds against pathogenic fungi was found to be selective. Compound 1 was highly inhibitory towards S. rolfsii (ED50 181.60 ± 0.58 μgmL(-1)) and R. solani (ED50 189.74 ± 1.03 μgmL(-1)). Availability of plant material and significant antifungal activity makes the plant a potential source of antifungal agent and that can be exploited for the development of a natural fungicide.
