A kind of rhodiola grandiflora seed processing method

Abstract

The invention provides a method for processing Rhodiola grandiflora seeds, the steps are as follows: a. Seed harvesting: when more than 50% of the follicle skin of Rhodiola grandiflora is yellowish-brown or red, the inflorescences are harvested; b. Primary separation of seeds: drying the harvested inflorescences in the shade, and then rubbing to separate the seeds from the follicles to obtain the primary product; c, screening; d, winnowing; e, storing the seeds. According to the method of the invention, the purity of the obtained Rhodiola grandiflora seeds is as high as 98%, and the seed quality is good.

Description

technical field [0001] The invention belongs to the technical field of Tibetan medicine, and in particular relates to a method for processing Rhodiola grandiflora seeds. Background technique [0002] Rhodiola crenulata (HK.f.et Thoms.) H.Ohba is a perennial herb of the genus Rhodiola in the sedum family. The inflorescence is corymbose, with many flowers and bracts; the flowers are large and have long stalks , dioecious; male flower sepals 5, narrowly triangular to lanceolate; petals 5, red, oblanceolate, with long claws, apex blunt; stamens 10, same length as petals; scales 5, nearly square to oblong; heart Bark 5, lanceolate, sterile; female flower follicles 5, erect, flower branches short, red after drying; seeds obovate, 1.5-2 mm long, with wings at both ends. The flowering period is June-July, and the fruit period is July-August. Produced in Tibet, northwestern Yunnan, and western Sichuan. Born in hillside grasslands, bushes, and rock crevices at an altitude of 2800-5...

AI Technical Summary

Problems solved by technology

[0005] The inventor found in actual planting work that due to the irregular shape of Rhodiola grandiflora seeds and wings at both ends, it is difficult to separate them from impurities by conventional methods; and because the seeds are extremely small and light in weight, they cannot be separated from impurities by water separation. The purpose of separation leads to low seed clarity and low quality, so the utilization rate of seeds during planting is low, and the amount of seeds used is large but the yield is still low, which seriously affects the development and utilization of Rhodiola grandiflorum resources.
