To investigate the effects of six common drying methods on the quality of different specifications of Sophorae Flos, in order to select their suitable drying methods. According to appearance and morphology, Sophorae Flos was divided into the following three specifications: flower bud type(HL), half-open type(BK) and blooming type(SK). All specifications of samples were treated with shade-drying method(25 ℃, natural temperature), sun-drying method, hot-air-drying method(60, 105 ℃), and drying method(60 ℃) after steaming. The contents of total flavonoids, rutin, narcissus, quercetin, isorhamnetin, and Fe~(3+) reducing ability, DPPH free radical scavenging ability, ABTS free radical scavenging ability and fluorescence recovery after photobleaching(FRAP) were detected by UV, HPLC and colorimetry, respectively. Principal component analysis(PCA), cluster analysis(CA) and correlation analysis were used to comprehensively evaluate the quality of samples. According to the results, there were significant differences in the effect of drying methods on different specifications of samples. The drying method(60 ℃) after steaming was suitable for HL and BK, while the hot-air-drying method(60 ℃) was suitable for SK. When the fresh medicinal materials could not be treated in time, they should be spread out in a cool and ventilated place. Under high and low temperature conditions, the quality of three specifications of Sophorae Flos would be reduced. The hot-air-drying method(105 ℃) and shade-drying method(25 ℃) were not suitable for the treatment of fresh flowers and flower buds of Sophora japonicus. There were obviously differences of chemical compositions and antioxidant activities among the three specifications of samples. Therefore, the specifications of medicinal materials should be controlled to ensure the uniform quality. The study provided the abundant data reference for the selection of appropriate drying methods for the three specifications of Sophorae Flos, and useful exploration for the classification and processing of medicinal materials of flowers.

To study the effects of different drying methods on the quality of male flowers of Eucommia ulmoides(MFOEU), we treated fresh MFOEU samples with drying in the shade(DS), vacuum freeze drying(VFD), high-or low-temperature hot air drying(HTHAD, LTHAD), microwave drying(MD), and vacuum drying(VD), respectively. The color, total flavonoid content, total polysaccharide content, and main active components such as geniposide, geniposidic acid, rutin, chlorogenic acid, galuteolin, pinoresinol diglucoside, and aucubin in MFOEU were taken as the evaluation indicators. The quality of MFOEU was comprehensively evaluated by entropy weight method combined with color index method, partial least squares discriminant analysis and content clustering heat map. The experimental results showed that VFD and DS basically kept the original color of MFOEU. The MFOEU treated with MD had higher content of total polysaccharides, phenylpropanoids, lignans, and iridoids. The MFOEU treated with LTHAD had higher content of total flavonoids and that treated with VD had lower content of active components. According to the results of comprehensive evaluation, the quality of MFOEU dried with different methods followed the order of MD>HTHAD>VFD>LTHAD>DS>VD. Considering the color of MFOEU, the suitable drying methods were DS and VFD. Considering the color, active components, and economic benefits of MFOEU, MD was the suitable drying method. The results of this study are of a reference value for the determination of suitable methods for MFOEU processing in the producing areas.

Male infertility has become a problem worldwide, and recent research has emphasized the development of more effective therapy options. Among natural compounds, rutin has been widely studied for its potential to treat dysfunction related to male infertility, including a reduction in sperm quality, spermatogenesis disruption and structural disruption in the testis. A thorough review of scientific literature published in several databases, including Google Scholar, PubMed/MEDLINE and Scopus, was used to synthesize the present state of research on the role of rutin in male reproductive health. Rutin has been shown to possess antiapoptotic, antioxidant and anti-inflammatory activities, among others, which are crucial in the management of male infertility. Numerous investigations have shown that rutin protects against male infertility and have explored the underlying mechanisms involved. The present review, therefore, assesses the therapeutic mechanisms involved in male infertility treatment using rutin. Rutin was able to mitigate the induced oxidative stress, apoptosis, inflammation, and related physiological processes that can cause testicular dysfunction.

This study aimed to explore the correlation of the content of 15 non-crocin components of Gardeniae Fructus with its external properties(shape and color). The fruit shape was quantified according to the length/diameter measured by ruler and vernier calliper and the chromaticity values L~*, a~*, b~*, and ΔE~* of all samples were determined by chroma meter. Chromatographic separation was conducted on a Welch Ultimate XB C_(18) column(4.6 mm×250 mm, 5 μm) under gradient elution with acetonitrile solution(A) and 0.1% formic acid aqueous solution(B) as the mobile phase at a flow rate of 1.0 mL·min~(-1). The column temperature was 30 ℃ and the detection wavelength was 238 nm. The high-performance liquid chromatography(HPLC) method was established for simultaneous determination of the content of eight iridoid glycosides, six phenolic acids, and one flavonoid in 21 batches of Gardeniae Fructus samples. The correlation of the content of the 15 components with shapes and chromaticity values in each sample was analyzed by multivariate statistical analysis. According to the circulation situation and traditional experience, 21 batches of Gardeniae Fructus samples were divided into three categories, namely 14 batches of Jiangxi products(small and round, red and yellow), 4 batches of Fujian products(oval, red) and 3 batches of Shuizhizi(Gardenia jasminoides, longest, reddest). The Gardeniae Fructus samples were sequenced as Jiangxi products(1.71) < Fujian products(1.99) < Shuizhizi(2.55) in terms of the length/diameter average, Jiangxi products(17.7) < Fujian products(19.7) ≈ Shuizhizi(19.6) in terms of average value of a~*(red and green), Jiangxi products(24.4) > Fujian products(19.2) ≈ Shuizhizi(19.3) in terms of b~*(yellow and blue), and Jiangxi products(49.8) > Fujian products(48.0) ≈ Shuizhizi(47.8) in terms of L~*(brightness). The total content of the 15 components, 8 iridoid glycosides, 6 phenolic acids, and rutin in Jiangxi products was in the ranges of 65.53-99.64, 52.15-89.16, 6.10-11.83, and 0.145-1.81 mg·g~(-1), respectively. The total amount of the 15 components, 8 iridoid glycosides, 6 phenolic acids, and rutin in Fujian products was in the ranges of 69.33-94.35, 63.52-85.19, 5.39-8.41, and 0.333-0.757 mg·g~(-1), respectively. In Shuizhizi, the total content of the 15 components, 8 iridoid glycosides, 6 phenolic acids, and rutin was in the ranges of 77.35-85.98, 68.69-76.56, 7.30-9.05, and 0.368-0.697 mg·g~(-1), respectively. Pearson correlation analysis revealed that Gardeniae Fructus with leaner and longer fruit shape possessed lower content of total phenolic acids(the sum of the six phenolic acids) and rutin, but the correlation with iridoid glycosides was not high. Additionally, the higher content of total phenolic acids and rutin denoted the yellow coloration of Gardeniae Fructus, and the higher content of cryptochlorogenic acid, chlorogenic acid, and rutin meant the brighter color of Gardeniae Fructus. However, the higher content of geniposide and neochlorogenic acid and the lower content of deacetyl asperulosidic acid methyl ester led to the red coloration of Gardeniae Fructus. The results indicated that the morphological characters of Gardeniae Fructus were closely related to its chemical components. The more round shape and the yellower color reflected the higher content of phenolic acids and flavonoid, and Gardeniae Fructus with redder color had higher content of geniposide. OPLA-DA showed that the length/diameter and the content of six iridoid glycosides(gardoside, shanzhiside, gardenoside, genipin 1-gentiobioside, 6β-hydroxy geniposide, and deacetyl asperulosidic acid methyl ester), two phenolic acids(neochlorogenic acid and cryptochlorogenic acid) and rutin could be used as markers to distinguish three types of samples. This study provided experimental data for the scientific connotation of "quality evaluation through morphological identification" of Gardeniae Fructus.
