“…They include numerous flavonol derivatives , mainly quercetin and kaempferol glycosides, as well as a few flavone glycosides, such as acacetin, luteolin, and diosmetin glycosides (36-40) (l " Table 2, Fig. 2) [13,[25][26][27][28][29][30][31][32][33][34][35][36]. In addition, epigallocatechin-3-Osyringate (41) [36] and an ethenylamino-substituted anthocyanidin with a biogenetically unlikely structure [37] have been reported.…”

While these reviews describe various compounds and bioactivities, none of them addresses the pharmacological and clinical data that support the therapeutic use of Bryophyllum preparations in European countries. The present review focuses on B. pinnatum, but the few data available on Bryophyllum daigremontianum, Bryophyllum delagoense, and the hybrid Bryophyllum daigremontianum x tubiflorum have also been included. The German homeopathic pharmacopeia (HAB) 2014 [5] lists the two species B. pinnatum and B. daigremontianum as officinal in its monography "Bryophyllum Rh", and both have been used in AM. B. delagoense was introduced in the 1980s as an anthroposophic medicinal product in Germany, primarily for sedative purposes (Personal communication, Dr. med. Siegward-M. Elsas, see Acknowledgments).

“…Their presence in the walls of epidermal cells is generally associated with UV protection, whereas the presence of mesophyll cells in vacuoles and chloroplasts is linked with reactive oxygen species scavenging [1]. According to many reports, UV-B radiation increases flavonoid levels in young plants [2,19,21,25]. In this study, the concentrations of individual flavones indicate that the effect of UV-B is genetically determined ( Table 2).…”

“…For instance, in the leaves of Hydrocotyle leucocephala, quercetin derivatives accumulated under exposure to UV-B, thus reducing the concentrations of kaempferol glycosides and chlorogenic acid [20]. The flavonoid profile of broccoli sprouts was also modified under exposure to UV-B irradiation [21].…”

The impact of short-term UV-B treatment on the content of individual flavonoids and photosynthetic pigments in cotyledons and the growth of common buckwheat (Fagopyrum esculentum Moench) seedlings was investigated. Seeds of four common buckwheat cultivars were germinated in darkness over a period of 4 days and acclimatized for 2 days under a 16/8 h light/dark photoperiod at 24/18 °C day/night, and exposure to 100-120 μmol • m -2 • s -1 of photosynthetically active radiation (PAR). Seedlings were divided into three batches, including two batches subjected to different doses of UV-B (5 W • m -2 and 10 W • m -2 , one hour per day) for 5 days, and a control group exposed to PAR only. Exposure to UV-B increased anthocyanin levels in the cotyledons of all examined cultivars, it inhibited hypocotyl elongation, but did not affect the content of photosynthetic pigments. Flavone concentrations increased in cv. Red Corolla and Kora, remained constant in cv. Panda and decreased in cv. Hruszowska. Exposure to UV-B decreased rutin levels in cv. Hruszowska, but not in the remaining cultivars. Cultivars Hruszowska, Panda and Kora appeared to be less resistant to UV-B than Red Corolla. Higher resistance to UV-B radiation in Red Corolla can probably be attributed to its higher content of anthocyanins and rutin in comparison with the remaining cultivars.

“…Total quercetin found in a high concentration of 253 mg/kg. It resembles other research [28] which counted the level of each quercetin glycoside in K. pinnata (Lmk) Pers leaves. Since quercetin has anti-inflammatory [30], antinociceptive, antioxidant [31], and immunosuppressive [32] effects, quercetin can be an active marker compound in this research.…”

Objective: The aim of this research was to measure the effects of the ethyl acetate fraction of Kalanchoe pinnata (Lmk) Pers (EF-KP) on lupus arthritis mice. Methods:The research was performed by testing of CD123 + interferon-α (IFN-α + ) dendritic cells and CD68 + interleukin 6 (IL-6 + ) macrophages as the main biomarkers using flow cytometry method, and then, the outcomes were directly observed in the joint's tissue structure. The results of the research were analyzed using statistics. Results IL-6+ macrophages but not significantly. Finally, the outcome to the grade of joint damage was scored using Pritzker method. The treated groups have one grade lower, and the joint spaces were narrower than the untreated group. Conclusion:The results show the ability of the active compounds in EF-KP, which are comparable to 0.042 mg/kg of quercetin, to inhibit the progress of lupus arthritis pathogenesis in mice. It might reveals the effectiveness of the EF-KP in human with lupus arthritis. However, the further clinical research is necessary.
