... Synotis (Clarke 1876: 177) Jeffrey & Chen (1984: 285) (Asteraceae, Senecioneae) is mainly distributed in the Sino-Himalayan region. It includes about 60 species, with 48 species occurring in China (Jeffrey & Chen 1984;Chen 1999;Chen et al. 2011;Tang et al. 2013;Tong et al. 2017;Zhao et al. 2023). Based on its sub-shrubby habit and anther bases with sterile tailed auricles, Synotis was segregated from Senecio Linnaeus (1753: 866) into a separate genus (Jeffrey & Chen 1984). ...

... Despite this, Leptochilus was commonly recognized as a small genus with 25 "indistinct" species (Zhang and Nooteboom, 2013). Recently, new species and combinations have been continuously added to Leptochilus, partially increasing the species number of the genus (Zhang et al., 2015(Zhang et al., , 2024Zhao et al., 2017;Liang et al., 2020;Fujiwara et al., 2023;Wei et al., 2023;Yu et al., 2024). The currently defined Leptochilus is distributed from East Asia, South Asia to Southeast Asia (Fig. 1). ...

... They consist of over 579 species and 51 genera with the major secondary metabolites being terpenoids and limonoids along with minor compounds such as flavonoids, lignans, chromones, and phenolics [1]. The biological activities of the Meliaceae family include cytotoxic [2][3][4][5][6], antiviral [7][8][9][10], antiplasmodial [11][12][13][14], antioxidant [15][16][17][18], antimicrobial [19][20][21][22], antifeedant [23][24][25][26], and anti-inflammation [27][28][29][30][31]. ...

... We also analyzed the expression of three genes regulating the cell cycle: PCNA, CCND1 (G1/S-phase transition), and CDKN1A (G1/S-phase transition blocker). Normal liver regeneration is characterized by an increase in the expression of all three regulators of the cell cycle on the 3rd day after 70% PH [29]. After 30% PH, the expression remains unchanged, which corresponds to two different mechanisms underlying liver regeneration at different volumes of resection [1,15,30]. ...

... In recent years, several new species and new records of this genus, including I. longiaristata, I. tripetala, I. wawuensis, I. longlinensis, I. wutaishanensis, I. longshanensis, I. lihengiana and I. cavaleriei have been discovered in southwest China (Ding et al. 2016;Xue et al. 2020;Liao et al. 2021;Peng et al. 2021;Song et al. 2021;Huang et al. 2023). These findings underscore the presence of numerous potential new species awaiting discovery within this diverse genus. ...

... Pregnane steroids are secondary metabolites with a signicant role in various biological systems used by humans. 1 These compounds are typically derived from higher plants and oen show a wide range of biological activities due to diverse structures, which have 21 carbons known as the pregnane skeleton ( Fig. 1). 2 In addition, the syntheses from cholesterol are carried out through complex biosynthetic pathways and are known for structural complexity, which includes multiple rings as well as functional groups and substituents. Steroids are also described as natural hormones found in the human body. ...

... However, the odontoid petal margin can help us to distinguish all known species in this genus. After consulting relevant literature (Wang et al., 1998;Li and Wang, 2005;Wei et al., 2010;Shui et al., 2020) as well as collections of different herbaria (e. g. E, K, P, HN, IBK, IBSC, KUN, LE, PE, VNF, VNMN), we identified these plants as a new species by its morphological characters. ...
