A relatively simple and short procedure for the quantitative determination of gypsogenin saponins was performed to evaluate homeopathic tinctures in which those compounds can be regarded as one of the active constituents. This method comprises partial hydrolysis of saponins, subsequent extraction of liberated prosaponin (gypsogenin 3-O-glucuronide) and its analysis by high performance liquid chromatography. Glycyrrhizic acid was used as an internal standard. This method was successfully applied to the analysis of mother tinctures obtained from Saponaria officinalis. Thus, the determination of triterpenoid saponins can be used as a convenient and sufficient method of standardization of selected homeopathic tinctures.

Astragalus mongholicus, commonly used in Traditional Chinese Medicine (TCM), contains significant amounts of triterpene saponins – astragalosides, which possess a wide variety of pharmacological actions, including the treatment of cardiovascular and respiratory diseases. The present study was performed to develop a fast and effective extraction method of saponins from crude plant material using Twisselmann-type apparatus. Moreover, a detailed comparison between Soxhlet and Twisselmann apparatus was performed to explain the advantages and disadvantages of their applications. The content of astragaloside IV – the major saponin of A. mongholicus extracts and chosen as an extraction efficiency marker ‒ was determined by means of RP-HPLCELSD chromatography in an herein optimized method. Twisselmann extraction shortened its duration from 4 to 2 hours in comparison with the Soxhlet method ‒ a generally accepted method preparation for this extract. The effectiveness of both apparatus was alike (3.24 ± 0.44 mg and 3.48 ± 0.26 mg of astragaloside IV/ 4g of powdered root for 2 hours in Twisselmann and 4 hours in Soxhlet apparatus). Compared with a pharmacopoeial method, the application of Twisselmann apparatus enabled a decrease in analysis time of 50%, which is of high significance, especially for large, scaled-up industrial scale.

The mechanism of floral mutation including double flowers in plant species can be explained by the ABCDE model which represents the relationship between MADS-box transcription factor genes and floral morphogenesis. The ornamental importance of Cyclamen led to the creation of double-flowered cultivars caused by the repression of AG-like gene expression in whorl 3. Modifications in these genes also influence the accumulation of different bioactive compounds depending on species and/or variety. In antiquity, cyclamen plants were recognized for their therapeutic qualities and later gained importance due to their content in saponins, which have been reported to exhibit anti-cancer, anti-inflammatory and antibacterial effects, and also to alleviate symptoms in acute rhinosinusitis patients. Furthermore, the extracts and isolated compounds are used as treatments in a wide range of diseases. In this review, we describe the transcription factors and their role in the development and ABCDE model formation of organs which led to the development of double-petal and fragrant varieties. Additionally, we describe the potential mechanisms of action underlying the therapeutic effects of saponin extracts against cancers and inflammatory disorders and their potential as a pharmacological agent in clinical studies.
