ABSTRACT
Corynaea crassa is a root hemiparasitc plant infrequent in nature. There is little information regarding their natural history, in particular their host range. In this study we dig 32 tubers and followed their parasitized roots to determine the species host. We found Bocconia frutescens (Papaveraceae), Verbesina sp. (Asteraceae), Cayaponia sp. (Cucurbitaceae) y Palicourea sp.(Rubiaceae) as natural hosts of C. crassa. This is the first host record available for C. crassa and provides some bases for its conservation in natural habitats.
Corynaea crassa es una planta hemiparásita de raíz poco común y de la cual sabemos muy poco acerca de su historia natural y en particular sobre su rango de hospederos. En este estudio excavamos 32 tubérculos de dicha especie y seguimos las raíces que estaban parasitando para determinar su identidad. Encontramos Bocconia frutescens (Papaveraceae), Verbesina sp. (Asteraceae), Cayaponia sp. (Cucurbitaceae) y Palicourea sp. (Rubiaceae). Este es el primer registro de hospederos disponible para la especies y este tipo de información es de gran utilidad para las conservación de C. crassa en hábitats naturales.
ABSTRACT
Objective To investigate the chemical constituents of Balanophora simaoensis. Methods Chromatography and spectra were used to isolate the constituents and elucidate their structures. Results Four compounds were isolated from whole plant of B. simaoensis and elucidated as methylconiferin (Ⅰ), butylconiferin (Ⅱ), 4-O-?-D-glucopyranosyl confieryl aldehyde (Ⅲ), and brevifolin (Ⅳ), respectively. Conclusion Butylconiferin is a new compound.
