This study was designed to investigate the effects of different drying methods on the main components, crystal properties, morphological properties, and in vitro digestibility properties of Fritillaria thunbergii Miq. flour. The results showed that the total peimine and peiminine contents ranged between 0.093% and 0.245%, insoluble amylose from 4.57% to 10.93%, and the water-binding capacity (WBC) from 144.09% to 192.28%. Compared with the sun-drying method, microwave drying significantly decreased the total peimine and peiminine content, protein, soluble amylose, resistant starch (RS), solubility, swelling power, and relative crystallinity, while increasing the insoluble amylose content and WBC. The microwave-dried sample showed significant changes in starch content, as evident from the scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy findings. Low levels of rapidly digestible starch and glucose and high RS levels were found in the hot air-dried and freeze-dried samples. Thus, F. thunbergii flour can be used as medicinal excipients, as health products, and in paints by these results. Furthermore, this flour finds more uses when subjected to chemical or physical treatment in medicinal, paint, and food processors.

Thunberg fritillary bulb (the dry bulbs of Fritillaria thunbergii Miq.), a traditional Chinese Medicine, is widely applied as an expectorant and antitussive. In this investigation, the primary metabolites of bulbs, flowers, leaves, and stems of F. thunbergii were analyzed by gas chromatography–mass spectrometry. Principal component analysis, partial least squares-discriminate analysis, orthogonal projection to latent structures-discriminate analysis, and heat map analysis showed that there were dissimilar metabolites, and a negative correlation between amino acids and saccharides in different analytes. Furthermore, carbodiimide, tryptophan, glucose-6-phosphate, xylose, 2-piperidinecarboxylic acid, monoamidomalonic acid, phenylalanine, and histidine were found to play an important role in the plant metabolism net of F. thunbergii .

There is a high market demand for the dried bulb of Fritillaria thunbergii Miq. because of its use to treat airway inflammatory and endocrine system diseases. Although F. thunbergii requires more potassium than nitrogen and phosphorus during development, the response of F. thunbergii to potassium has rarely been studied. Field experiments were conducted in 2016/2017 and 2017/2018 with two F. thunbergii cultivars under six levels of potassium fertilization (0, 40, 80, 120, 160 and 200 kg K 2 O ha −1 ) to investigate the effects of potassium application on F. thunbergii yield, quality, and potassium utilization efficiency. Results showed that potassium fertilization increased the bulb yield, bulb quality (peimine and peiminine content), and net income by 6.4–23.8 %, 2.1–26.6 % and 47.7–205.4 %, respectively. More biomass and potassium were partitioned to underground parts when potassium application increased. The yield and quality of the bulb were positively correlated with potassium accumulation in the underground part. The economic benefit of F. thunbergii is stable at 120–160 kg K 2 O ha −1 , while the potassium utilization efficiency was reasonable at 80–120 kg K 2 O ha −1 . In summary, potassium application is an effective strategy to simultaneously improve bulb yield and quality in F. thunbergii . Considering the economic and environmental benefits, a potassium application rate of 120 kg K 2 O ha −1 is optimal for F. thunbergii cultivation.
