Panax notoginseng (Burk.) F. H. is a genuine medicinal material in Yunnan Province. As accessories, P. notoginseng leaves mainly contain protopanaxadiol saponins. The preliminary findings have indicated that P. notoginseng leaves contribute to its significant pharmacological effects and have been administrated to tranquilize and treat cancer and nerve injury. Saponins from P. notoginseng leaves were isolated and purified by different chromatographic methods, and the structures of 1–22 were elucidated mainly through comprehensive analyses of spectroscopic data. Moreover, the SH-SY5Y cells protection bioactivities of all isolated compounds were tested by establishing L-glutamate models for nerve cell injury. As a result, twenty-two saponins, including eight dammarane saponins, namely notoginsenosides SL1-SL8 (1–8), were identified as new compounds, together with fourteen known compounds, namely notoginsenoside NL-A3 (9), ginsenoside Rc (10), gypenoside IX (11), gypenoside XVII (12), notoginsenoside Fc (13), quinquenoside L3 (14), notoginsenoside NL-B1 (15), notoginsenoside NL-C2 (16), notoginsenoside NL-H2 (17), notoginsenoside NL-H1 (18), vina-ginsenoside R13 (19), ginsenoside II (20), majoroside F4 (21), and notoginsenoside LK4 (22). Among them, notoginsenoside SL1 (1), notoginsenoside SL3 (3), notoginsenoside NL-A3 (9), and ginsenoside Rc (10) showed slight protective effects against L-glutamate-induced nerve cell injury (30 µM).

The fruits of Solanum torvum Swartz, a wild relative of eggplant, are consumed as a wild vegetable in tropical regions of Africa, Asia, and South America. In traditional Chinese medicine, it is believed to have anti-inflammatory and sedative effects. In the Philippines, water decoction is used to treat hyperactivity disorder. Twenty-two steroidal saponins were isolated and purified from the fruits grown in Yunnan, China, including six new compounds: torvosides U–Z (1–6). During drying and cooking, the saponins may undergo transformation, resulting in small amounts of sapogenins. These transformations can include dehydration of hydroxyl groups at position C22, formation of double bonds at position 20, 22 or 22, 23, and even formation of peroxide products. Saponin compounds torvoside X (4), torvoside Y (5), torvoside A (7), and (25S)-3-oxo-5α-spirostan-6α-yl-O-β-d-xylopyranoside (20), which are glycosylated at C-6, showed certain anti-epileptic activity in a pentylenetetrazole-induced zebrafish seizure model. No antiproliferative activity was detected when tested on the cancer cell line HepG2, and no hepatotoxic effect was noted on normal liver cell line LO2.

Alpine plants face intense ultraviolet (UV) radiation in high-altitude ecosystems, necessitating adaptive mechanisms like tyrosinase-mediated phenolic metabolism for UV protection. This study aimed to characterize the phenolic profile of Corallodiscus flabellatus (or C. flabellata) and elucidate its mechanistic interactions with tyrosinase under high-altitude environments with intense ultraviolet (UV) radiation. Two novel phenylethanoid glycosides (PhGs) and seven known compounds were isolated using silica gel, ODS, and preparative HPLC, with structures determined via NMR, HR-ESI-MS, and acid hydrolysis. Tyrosinase (EC 1.14.18.1) inhibition assays revealed divergent effects: compound 7 (containing a caffeoyl moiety) exhibited potent inhibition (IC50 = 0.23 μM), comparable to arbutin, while other PhGs displayed activation or biphasic responses. Molecular docking analysis demonstrated that compound 7 stabilized tyrosinase via π-π stacking with Phe264 and Cu2+ coordination, whereas activating compounds likely acted as substrates. These findings elucidate the dual regulatory function of PhGs, which activate tyrosinase to counteract acute ultraviolet-induced stress and inhibit its activity to attenuate oxidative overload, thereby advancing our understanding of alpine plant adaptation mechanisms.
