The red stigmas of saffron are one of the most expensive spices in the world and serve as a traditional Chinese medicine. More saffron has been cultivated in China, and different drying technologies have been studied. However, a comprehensive and comparative analysis of different drying approaches has not been well studied.

Materials And Methods: The influence of crocin on growth, apoptosis, and autophagy and its mutual relations were analyzed by Cell Counting Kit-8 assay, flow cytometer, EGFP-LC3 puncta analysis, and Western blot in HCC cells.
Article Synopsis
- The study used the phenol-sulfuric acid method to analyze the polysaccharide content in Dendrobium officinale leaves and stems, revealing significant differences in composition and quantity.
- Polysaccharides in the stems had a higher content and were primarily made up of mannose and glucose, while the leaves contained an acid heteropolysaccharide made up of five different monosaccharides.
- The analysis of chromatographic fingerprints showed a high similarity among the samples, which supports the potential to expand the medicinal uses of D. officinale beyond just the stems.

Article Synopsis
- The study aimed to identify a specific chemical marker, naringenin, in Dendrobium officinale and establish a method to measure its content across different sources and growth years.
- Naringenin content was analyzed using HPLC, achieving good linearity and an average recovery rate of 96.3%.
- The findings indicate that the HPLC method is accurate and reliable for quantifying naringenin in D. officinale, with the highest levels found in 3-year-old plants and variations depending on the source.
Objective: To establish the method of specific chromatogram analysis of ether extract of Dendrobium officinale for identification of D. officinale.
Method: Chromatographic separation was carried out at 30 degrees C on an Ultimate C18 column (4.
[Experimental studies of hypoglycemic action on total flavone of Ampelopsis grossedentata from Guangxi].

Objective: To study hypoglycemic action of total flavone (GXTF) of Ampelopsis grossedentata from Guangxi by observing the effects of GXTF on blood glucose levels in many strain animal models.
Method: The blood glucose levels in many strain animal models were determined after oral administration, with the models of diabetes induced by alloxan, of hyperglycemic mice induced by epinephrine and glucose, and normal mice.
Result: GXTF had better therapeutical action on diabetes mice induced by alloxan, and could significantly lowered the blood glucose levels of hyperglycemic mice induced by epinephrine and glucose, but had no significant effects on blood glucose levels of normal mice.
