    ¡Hola, heboca! ¡Bienvenido/a al foro! Bueno, esa palabra no la encuentro por ningún lado. ¿Podrías dar un poco de contexto, la oración donde aparece?
    ¿Es un término técnico?

    Saludos. :)

    I found this on the Ask Jeeves web site. Hope it helps.

    Flaxseed contains a health-boosting, disease-preventing compound called flax lignan, and scientists from the Saskatoon Research Centre (SRC) have developed the technology for extracting and purifying this compound.

    Flax lignan is believed to be helpful in the fight against heart disease, cancer, and kidney disease. Saskatoon researchers have teamed up with medical research scientists, and together the group is working to discover potential uses for flax lignan. Already, the team has licensed the technology to an agricultural processing company that will produce and market a flax lignan complex for use in functional foods, nutraceuticals, pharmaceuticals, animal feed additives and veterinary products

    Hola:

    Parece ser que en castellano también se dice lignan:

    Lo que debe saber sobre las propiedades de la linaza

    Únicamente en la semilla de linaza se encuentran los ácidos esenciales perfectamente balanceados. Reportes publicados par el Instituto Karolinske en Suiza muestran que la linaza contiene 800 mg./kg de lignan (un agente anticancerígeno muy estudiado) 100 veces más propiedades que los mejores granos integrales. Las bondades de lignan en la prevención del cáncer de mama y colon están al alcance de toda la gente simplemente con añadir semilla de linaza molida a su dieta.

    Espero sirva, chau.

    Abstract: Lignans and neolignans are a large group of natural products characterised by the coupling of two C6C3 units. For nomenclature purposes the C6C3 unit is treated as propylbenzene and numbered from 1 to 6 in the ring, starting from the propyl group, and with the propyl group numbered from 7 to 9, starting from the benzene ring. With the second C6C3 unit the numbers are primed. When the two C6C3 units are linked by a bond between positions 8 and 8' the compound is referred to and named as a lignan. In the absence of the C-8 to C-8' bond, and where the two C6C3 units are linked by a carbon-carbon bond it is referred to and named as a neolignan. The linkage with neolignans may include C-8 or C-8'. Where there are no direct carbon-carbon bonds between the C6C3 units and they are linked by an ether oxygen atom the compound is named as an oxyneolignan. The nomenclature provides for the naming of additional rings and other modifications following standard organic nomenclature procedures for naming natural products. Provision is included to name the higher homologues. The sesquineolignans have three C6C3 units and dineolignans have four C6C3 units.

    This is what I found,
    I would recommend you to keep searching in Google.
