“…Likewise, Walters et al (2005) found similar results when they quantified fatty acids in sunflower seeds (Helianthus annuus L.) The fatty acids of cotyledons are predominantly linoleic and oleic acids. Also, Gómez-Tejero et al (2006) found a larger proportion of unsaturated fatty acids in seeds of Swietenia macrophylla King and other forest species.…”

In Mexico, 44 thousand hectares are planted with tomatillo or husk tomato (Physalis philadelphica Lam.), which occupies fourth place among the country's vegetable species. However, research on this species is scarce, especially that related to the process of seed deterioration. We studied the effects of deterioration in tomatillo seed, var. CHFl-Chapingo, stored from 2-mo up to 7 yr with no climate control, 18.2 ± 5 °C and 41 ± 10% relative humidity, on physiological and biochemical variables during germination. It was found that germination, vigor, and respiratory activity decrease significantly from the first year of storage; thus, after 7 yr, germination and vigor decreased 99%, and respiratory activity of seed after 48 h imbibition decreased 78%. Linoleic acid (unsaturated) content correlated positively with germination (R = 0.78**) and with speed of radicle emergence (R = 0.79**). Germination correlated with speed of radicle emergence (R = 0.99**) and with respiratory activity after 48 h of imbibition (R = 0.79**). Both respiratory activity and fatty acid content are involved in natural deterioration of tomatillo seed.

Regarding the mahogany seed, it is known that the seeds are rich in fats, however the advantage is that they contain a higher proportion of unsaturated fatty acids (Gómez et al, 2006) being beneficial to health.

The anti-hyperglycemic activity in ethanolic extracts of mahogany seeds (Swietenia macrophylla king) and medlar leaves (Eriobotrya japonica lindl) have shown to be promising candidates for use in patients with type 2 Diabetes Mellitus due to their high hypoglycemic capacity. In this study, the nutritional composition of the plant material used and a comparison of the effect of ethanolic extracts of mahogany seeds (Swietenia), medlar leaves (Eriobotrya), and metformin on biochemical parameters of hyperglycemic Wistar rats were evaluated. Regarding the nutritional composition, it was found that loquat leaves have a high content of dietary fiber (35 g/100 g bs); while mahogany seed has a good amount of protein (19 %) and lipids (71 %). Swietenia was effective in controlling biochemical parameters of hyperglycemic rats, but at a lower level than metformin. In contrast, Eriobotrya reduced the glucose content, to values without significant differences from the control group in healthy rats. However, the content of cholesterol, triglycerides, and urea; as well as alanine aminotransferase activity, was lower in rats treated with Eriobotrya. In conclusion, both plants are an alternative to control biochemical parameters at normal levels in hyperglycemic individuals.

“…En cuanto a los ácidos grasos, el linoleico fue el de mayor concentración (de 87 a 93 % del total), seguido del oleico (de 4.4 a 6.9 %), el palmítico (de 1.4 a 4.2 %) y del esteárico (de 0.6 a 2 %) (Cuadro 2, Figura 1); los dos primeros ácidos grasos son insaturados y los otros dos saturados. En semillas, los ácidos grasos insaturados se ubican primordialmente en la membrana celular (Walters et al, 2005;Gómez-Tejero et al, 2006;Panobianco y Vieira, 2007), por lo que se infiere que la mayor parte de los ácidos observados en las semillas analizadas, provienen de este tipo de membranas. Al respecto, Pérez-Camacho et al (2008) encontraron que el principal compuesto de reserva de la semilla de tomate de cáscara var.…”

Durante el almacenamiento, mecanismos de deterioro de la semilla disminuyen la germinación, la velocidad de crecimiento de la plántula y la tolerancia a condiciones adversas. El deterioro se puede evaluar con pruebas de envejecimiento artificial (EA). En este trabajo se evaluó el deterioro artificial de semilla de tomate de cáscara (Physalis ixocarpa Brot.) de la variedad ‘CHF1-Chapingo’, y la respuesta germinativa se correlacionó con el contenido de ácidos grasos totales y la tasa de respiración de semillas completas. En un primer experimento se utilizaron semillas envejecidas artificialmente en 55, 65 y 75 % de humedad relativa (HR) a 45 y 50 °C, durante 30 d; se evaluó la germinación (G, %), el vigor (velocidad de emergencia de radícula, VER, radículas d-1), y el contenido de ácidos grasos cuantificado mediante cromatografía con espectrómetro de masas. En un segundo experimento se utilizaron semillas envejecidas artificialmente en 50, 55, 60, 65, 70, 75 y 80 % de HR a 50 °C, durante 30 d y se evaluó germinación, VER, y actividad respiratoria a 72 h de imbibición. Se encontró que el ácido linoleico fue el de mayor concentración (87-93 % del total de ácidos grasos) en estas semillas, y que el aumento de calor y humedad redujo (P ≤ 0.5) la G y la VER, pero no al contenido de ácidos grasos. En el Experimento 1 la combinación de 50 °C y 65 % de HR disminuyó la G en 53 % y a la VER en 92 %, con respecto al testigo no tratado. En el experimento 2, el tratamiento de 50 °C con 65% de HR disminuyó la G en 21 % t la VER en 78 %, con respecto al tratamiento de 50 °C con 50 % de HR. La actividad respiratoria correlacionó con la disminución de germinación (r = 0.88) y de VER (r = 0.99), por lo cual la pérdida de la calidad fisiológica de la semilla se atribuye a la disminución en la tasa de respiración.
