Resumo: Abstract Biofertilizer Ning shield was composed of different strains of plant growth promotion bacteria. In this study, the plant growth promotion and root-knot nematode disease control potential on Trichosanthes kirilowii in the field were evaluated. The application of Ning shield significantly reduced the diseases severity caused by Meloidogyne incognita, the biocontrol efficacy could reached up to 51.08%. Ning shield could also promote the growth of T. kirilowii in the field by increasing seedling emergence, height and the root weight. The results showed that the Ning shield could enhance the production yield up to 36.26%. Ning shield could also promote the plant growth by increasing the contents of available nitrogen, phosphorus, potassium and organic matter, and increasing the contents of leaf chlorophyll and carotenoid pigment. Moreover, Ning shield could efficiently enhance the medicinal compositions of Trichosanthes, referring to the polysaccharides and trichosanthin. Therefore, Ning shield is a promising biofertilizer, which can offer beneficial effects to T. kirilowii growers, including the plant growth promotion, the biological control of root-knot disease and enhancement of the yield and the medicinal quality.

Título: Evaluation of the toxic potential of standardized extracts (hot water extract and cold ethanolic extract) of Trichosanthes cucumerina Linn. aerial parts / Evaluación de la toxicidad de extractos estandarizados (obtenidos con agua caliente y etanol frio) de partes aéreas de Trichosanthes cucumerina Linn

Resumo: Trichosanthes cucumerina Linn. is one of the medicinal plants that is often used in Sri Lankan traditional systems of medicine for the preparation of formulations to treat a variety of disease conditions. However, the toxic effects of T. cucumerina are not known. The aims of the present study were to (a) standardize hot water (HWE) and cold ethanolic (CEE) extracts of T. cucumerina aerial parts, and (b) evaluate toxic potential of the plant extracts. Both extracts were standardized by developing their densitograms and HPLC fingerprints and determination of physico – chemical parameters such as total ash, water soluble ash and acid insoluble ash. Administration of the HWE or CEE to mice did not result in acute or chronic toxic effects as evident from their effects on (a) liver and kidney functions and (c) hematological parameters and (d) fertility of male or female mice.In conclusion, the results of this study have revealed that standardized extracts of T. cucumerina at the doses tested do not produce any serious toxic side effects.

Trichosanthes cucumerina Linn. Es una de las plantas comunmente utilizadas en el sistema de medicina tradicional de Sri Lanka, en la preparación de formulaciones para el tratamiento de diversas enfermedades. Debido a que los efectos tóxicos de T. cucumerina no se conocen, los objetivos de este estudio fueron: (a) estandarizar los extractos obtenidos con agua caliente (EAC) y con etanol frío (EEF), y (b) evaluar la toxicidad de ambos extractos. Ambos extractos fueron estandarizados por obtención de sus densitogramas y huella digital con HPLC. Adicionalmente se determinaron parámetros fisicoquímicos, tales como: cenizas totales, cenizas solubles en agua y cenizas solubles en ácido. La administración de EAC y EEF a ratones no mostró efectos tóxicos agudos ni crónicos. Las funciones renales, hepáticas, estudios hematológicos y de fertilidad en machos y hembras fueron normales. Se concluye que los extractos estandarizados de T. cucumerina, a las dosis ensayadas no producen ningún efecto tóxico.

Título: Effect of ethanol extract of whole plant of Trichosanthes cucumerina var. cucumerina L. on gonadotropins, ovarian follicular kinetics and estrous cycle for screening of antifertility activity in Albino Rats / Efectos del etanol extraído de la planta completa de Trichosanthes cucumerina var. cucumerina L. sobre gonadotropinas, cinética folicular ovárica y ciclo para screening de actividad antifertilidad en Ratas Albinas

Resumo: Ethanol extract of whole plant of Trichosanthes cucumerina L. var. cucumerina was evaluated for antiovulatory activity in adult rats. The ethanol extract at the doses 200 and 400mg/kg body weight (orally) affected the normal estrous cycle showing a significant increase in estrus and metestrus phases and decrease in diestras and proestrus phases. The extract also significantly reduced the number of healthy follicles (Class I-Class VI) and corpora lutea and increased the number of regressing follicles (Stage IA, Stage IB, Stage IIA, and Stage IIB). The protein and glycogen content in the ovaries were significantly reduced in treated rats. The cholesterol level was significantly increased, whereas, the enzyme activities like 3b-HSD and 17b-HSD were significantly inhibited in the ovary of treated rats. Serum FSH and LH levels were significantly reduced in the treated groups were measured by RIA. In acute toxicity test, neither mortality nor change in the behavior or any other physiological activities in mice were observed in the treated groups. In chronic toxicity studies, no mortality was recorded and there were no significant differences in the body and organ weights were observed between controls and treated rats. Hematological analysis showed no significant differences in any of the parameters examined (RBC, WBC count and Hemoglobin estimation). These observations showed the antiovulatory activity of ethanol extract of whole plant of Trichosanthes cucumerina L. var. cucumerina in female albino rats.

El extracto de etanol de toda la planta de Trichosanthes cucumerina var. cucumerina (L.) se evaluó en cuanto a su actividad antiovulatoria en ratas adultas. El extracto de etanol en dosis de 200 y 400mg/kg de peso corporal (oral) afectó el ciclo normal estral, mostrando un aumentó significativo en las fases de estro y metaestro y la disminución de las fases de diestro y proestro. El extracto también redujo significativamente el número de folículos sanos (Clase I=Clase VI) y cuerpo lúteo y aumentó el número de folículos en regresión (etapa I, etapa IB, etapa II y etapa IIB). La proteína y el contenido de glucógeno en los ovarios se redujeron significativamente en las ratas tratadas. El nivel de colesterol aumentó significativamente, mientras que, actividad de las enzimas 3b-HSD y 17b-HSD se inhibió significativamente en el ovario de ratas tratadas. FSH sérico y los niveles de LH se redujeron significativamente en los grupos tratados y medidos por RÍA. En la prueba de toxicidad aguda, no hubo mortalidad ni cambio en el comportamiento fisiológico o de cualquier otra actividad en los grupos tratados de ratas. En estudios de toxicidad crónica, no se registró mortalidad y no hubo diferencias significativas en el peso corporal o el peso de los órganos entre los controles y las ratas tratadas. Los análisis hematológicos no mostraron diferencias significativas en ninguno de los parámetros examinados (eritrocitos, recuento de glóbulos blancos y estimación de hemoglobina). Estas observaciones mostraron la actividad antiovulatoria del extracto de etanol de toda la planta de Trichosanthes cucumerina var. cucumerina en ratas albinas hembras.
