Cirsium japonicum

One of the most exiting findings in this area is perhaps the isolation of Bt-CD, a neoclerodane diterpenoid from Baccharis trimera (Less) DC or carqueja (Brazil) used to treat rheumatism and diabetes that shows anti-phospholipase A2 activity (11). Note also the anti-phospholipase A2 and anti-inflammatory activity of Santolina chamaecy-parissus (12). Cirsium japonicum DC, Crossotephium chinense L. Makino, Inula chinensis Rupr. ex Maxim., and Sigesbeckia orientalis L. are used in Asia for the treatment of inflammatory conditions.

Several nematicidal acetylenic compounds have been isolated most possess thiophene structures and are from members of the Asteraceae family. Another recently isolated compound with this activity is (8/ ,9jR,10S)-9,10-epoxyhep-tadec-16-ene-4,6-diyne-8-ol (16) from Cirsium japonicum (Kawazuetal, 1980) (Fig. 3.13). l-Phenylhepta-l,3,5-triyne and 2-phenyl-5-(l -propynyl)-thiophene from Coreopsis lanceolata and Z-dehydromatricaria ester (5) from Solidago altissima have been shown to be fly ovicidal substances (Seigler, 1983).
