ABSTRACT
Objective: To investigate the influence of different parts and different harvest seasons on the yield and quality of Lonicerea Japonicae Flos (LJF), and to provide the reference for the reasonable harvest, lot division, and comprehensive utilization. Methods: After collecting samples from different parts at different periods, the growth index, yield, and chlorogenic acid and galuteolin contents of LJF were calculated and compared. Results: There were the significant differences in the growth and yield as well as the chlorogenic acid and galuteolin contents in different parts of LJF in different harvest seasons. Conclusion: The best collection period is before and during the completely white flower bud stage, and the first batch flower buds have the highest yield and the best quality, followed by the second batch. Branches and leaves of LJF contain the higher levels of chlorogenic acid and galuteolin, which could be extracted and utilized.
ABSTRACT
No presente trabalho, objetivou-se avaliar a época de colheita e a qualidade fisiológica de sementes de coentro produzidas no Norte de Minas Gerais. A primeira época de colheita das sementes foi realizada aos 15 dias após o florescimento pleno, quando aproximadamente 50 por cento das plantas apresentavam flores. As demais colheitas foram realizadas de 7 em 7 dias, até as sementes atingirem 14,0 por cento de umidade, fato que ocorreu na 6ª colheita. Imediatamente após cada colheita, as sementes foram avaliadas quanto ao teor de água, à germinação e ao vigor (testes de primeira contagem, emergência de plântulas e índice de velocidade de emergência). A maturidade fisiológica das sementes de coentro, cultivar Verdão, ocorre entre 42 a 44 dias após o florescimento, quando as sementes apresentam umidade em torno de 28,0 por cento, podendo a colheita ser realizada até 50 dias após o florescimento, quando as sementes apresentavam 14,0 por cento de umidade.
The present study aimed to evaluate the harvest season and physiological quality of coriander seeds produced in the North of Minas Gerais. The first season of harvest of the seeds was performed 15 days after full bloom, when approximately 50 percent of plants had flowers. The other crops were carried out 7 in 7 days, until the seeds reach 14,0 percent moisture, a fact that occurred in the 6th harvest. Immediately after each harvest, the seeds were evaluated for water content, germination and vigor tests (first count, seedling emergence and emergence speed index). The physiological maturity of coriander seeds, cultivate Verdão, occurs between 42 to 44 days after flowering, when the seeds had humidity around 28,0 percent at physiological maturity, the harvest may be held until 50 days after flowering, when seeds had 14,0 percent humidity.

INTRODUCCIÓN: el D004, un ingrediente activo promisorio en el tratamiento de la hiperplasia prostática benigna, se obtiene a partir del aceite del fruto de Roystonea regia (Kunth) OF Cook. Está compuesto por una mezcla de ácidos grasos libres que incluye los ácidos láurico y mirístico, ambos de gran interés por sus efectos farmacológicos. OBJETIVO: determinar la posible influencia de la época de colecta sobre el contenido de aceite y la concentración de los ácidos láurico y mirístico de los frutos de R regia. MÉTODOS: se colectaron cada mes, durante 2 años, frutos maduros de R regia en una población seleccionada. En las muestras secas y molidas se determinó el contenido de aceite gravimétricamente y el de ácidos grasos por cromatografía de gases. RESULTADOS: se encontraron diferencias estadísticas significativas en los contenidos de aceite y de los ácidos láurico y mirístico; no obstante, los contenidos determinados en todos los casos se mantuvieron dentro de las especificaciones calidad establecidas para el material vegetal. CONCLUSIONES: el material vegetal colectado durante todo el año puede ser empleado en la obtención del aceite de R. regia, materia prima empleada en la producción de D004
INTRODUCTION: D004, an promissory active ingredient in treatment and prevention of begnin prostatic hyperplasia, is obtained from the fruit oil of Roystonea regia (Kunth) OF Cook. It is composed by a mixture of free fatty acids including lauric and myristic acids, both very important by their pharmacological effects. OBJECTIVE: to determine the potential influence of harvest season on the oily content and the concentration of lauric and myristic acids from R regia fruits. METHODS: each month for two years, it was possible to collect mature fruits from R regia in a selected group. In dry and milled samples it was determined the oily content in a gravimetric way and that of fatty acids by gas chromatography. RESULTS: there were differences statistically significant in oily contents and of lauric and myristic acids; however, the contents determined in all the cases remained within the quality specifications established for the plant material. CONCLUSIONS: the plant material collected for all the year may be used in obtaining of R. regia oil, raw material used in the production of D004
