Abstract
The ethanol extract of the fungus Sarcodon scabripes collected from north-central British Columbia, Canada, showed strong antiproliferative activity. Bioassay-guided purification using liquid-liquid extraction and Sephadex LH-20 size-exclusion chromatography, followed by HPLC-MS and 1D/2D NMR analyses, led to the isolation of five known compounds; four p-terphenyl (1-4) derivatives and one phenolic aldehyde (5). Compounds 1, 4, and 5 were isolated for the first time from the Sarcodon genus. The cytotoxicity MTT assay showed that compounds 1-5 have antiproliferative activity against human cervical cancer cells (HeLa). For compounds 1-4, this is the first report of their antiproliferative activity against cancer cells. For compound 2, this is the first report on its bioactivity. To our knowledge, this is the first description of the isolation of bioactive constituents from S. scabripes.

Abstract
To provide a scientific reference for improving the sawdust cultivation of Sanghuangporus baumii, comparative studies were conducted on the contents of nutritional components and active components and the antioxidant activity of the fruiting bodies of S. baumii cultivated with sawdust and cut logs. The results indicate that, first, cultivation methods had little effect on the contents of crude fat and the measured 16 kinds of amino acids [including total essential amino acids (EAA), total nonessential amino acids (NEAA), EAA/NEAA, and EAA/total amino acid (TAA)], but had a great influence on the contents of crude protein, crude fiber and TAA. These results suggest that the nutritional content under sawdust cultivation was significantly higher than that under cut-log cultivation. Second, the cultivation methods had little effect on the content of triterpenoids but had a great effect on the contents of polysaccharides, total flavonoids and total phenols, which showed that cut-log cultivation was significantly higher than sawdust cultivation. Third, the cultivation methods had a great effect on the antioxidant activities (ABTS and FRAP), which showed that cut-log cultivation was significantly higher than sawdust cultivation. The contents of polysaccharides, total flavonoids, and total phenols and the ABTS and FRAP activities using sawdust cultivation were lower than those using cut-log cultivation, which may be related to the mushroom strains, cultivation medium formula and cultivation technology. The results provide a solid basis for the improvement and promotion of new cultivation technologies for S. baumii.

Abstract
Medicago sativa (alfalfa) is a widely used animal feed. However, its quality has been difficult to control due to the lack of appropriate marker compounds. Therefore, it is very necessary to select an appropriate quality marker (Q-marker) to control its quality. In this study, medium-pressure liquid chromatography and high-pressure liquid chromatography were employed to effectively prepare the separation of the Q-marker (L-tryptophan) from Medicago sativa. Firstly, using MCI GEL® CHP20P as the stationary phase, 2.5 g of the target fraction Fr3 was enriched from crude Medicago sativa extract (2.9 kg) by medium-pressure liquid chromatography. Secondly, Sephadex LH-20 was used to further separate Fr3 fractions, and the Fr34 fraction (358.3 mg) was enriched after 14 repetitions. Lastly, using the ReproSil-Pur C18 AQ preparative column, 63.4 mg of L-tryptophan was obtained by high-pressure liquid chromatography, and the purity was above 95%. The results showed that medium-pressure liquid chromatography (MCI GEL® CHP20P and Sephadex LH-20) combined with high-pressure liquid chromatography (ReproSil-Pur C18 AQ) could be used to effectively prepare the Q-marker from natural products with satisfactory purity.

Inoscavin A, a pyrone compound isolated from a Sanghuangporus vaninii extract, inhibits colon cancer cell growth and induces cell apoptosis via the hedgehog signaling pathway. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 96:153852. [PMID: 35026508 DOI: 10.1016/j.phymed.2021.153852] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/06/2021] [Revised: 11/02/2021] [Accepted: 11/06/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Sanghuangporus vaninii, a large precious medicinal fungus called Sanghuang in China, has significant antitumor activity. We previously reported that a Sanghuangporus vaninii extract could lead to apoptosis in HT-29 cells through the intrinsic apoptotic pathway. We further found that Inoscavin A exhibited anti-colon cancer activity, but its specific mechanisms have not been fully elucidated. METHODS Inoscavin A was obtained from Sanghuangporus vaninii by the classic phytochemical separation technology. The male BALB/c nude mice were injected with HT-29 colon cancer cells as animal model. In order to observe the pathological changes of tumor section, the hematoxylin-eosin(H&E) staining was applied in the histological analysis. Metabolomics was utilized for the investigation of the overall changes of serum metabolites in animal model, and the potential targets of Inoscavin A were analyzed by Ingenuity Pathway Analysis (IPA). We further employed a molecular docking approach to predict the degree of combination of Inoscavin A and Smo. Then we further performed Western blotting and immunofluorescence analysis to investigate the expression of proteins involved in Hh-related pathways in tumor tissues. In addition, the colony formation assay, scratch-wound assay and transwell migration and invasion assay were conducted to evaluate the anti-colon-cancer activity of Inoscavin A. Concurrently, the mitochondrial membrane potential assay and TUNEL apoptosis assay were detected to demonstrate the effect of Inoscavin A on promoting HT-29 cells apoptosis. Western blot experiments verified the anti-tumor effects of Inoscavin A were modulated the protein expression of Shh, Ptch1, Smo and Gli1 in HT-29 cells. RESULTS We showed that Inoscavin A, a pyrone compound isolated from the Sanghuangporus vaninii extract, exerted its antitumor activity in an HT-29 colon cancer cell xenograft mouse model. Subsequently, we first time prove that the antitumor effects of Inoscavin A were related to the hedgehog (Hh) signaling pathway. Furthermore, we demonstrated that Smo, the core receptor of the Hh pathway, was critical for the induction of apoptosis of Inoscavin A and that overexpression of this target could significantly rescue cell apoptosis induced by Inoscavin A treatment. CONCLUSION Thus, our studies first propose that the natural outgrowth Inoscavin A exerted its anti-cancer effects by inhibiting Smo to suppress the activity of the Hh pathway though inhibiting cell proliferation and promoting apoptosis. These findings further indicate that Inoscavin A will be expected to be a prospective remedical compound for the treatment of colon cancer.

Abstract
In this study, polyamide and MCI GEL® CHP20P were employed as stationary phases in medium pressure chromatography (MPC) for the efficient preparative separation of bergenin from Saxifraga atrata. Ethanol-water, methanol-water, and acetonitrile-water mobile phases all showed good enrichment capacity for bergenin fraction when polyamide was used as a stationary phase. After 5 cycles of polyamide MPC using acetonitrile/water, 1.2 g of bergenin fraction was isolated from 180 g Saxifraga atrata herb. Further purification of this fraction was conducted using MCI GEL® CHP20P styrene-divinylbenzene beads. The bergenin fraction was separated into two fractions, and after three runs of MPC, 714.2 mg of bergenin with purity above 99% was obtained. The results demonstrate that the combination of polyamide and styrene-divinylbenzene MPC can be utilized for preparative isolation of compounds from natural products with high yield and purity.

Abstract
Phellinus Quél is one of the largest genera of Hymenochaetaceae, which is comprised of about 220 species. Most Phellinus macro-fungi are perennial lignicolous mushrooms, which are widely distributed on Earth. Some Phellinus fungi are historically recorded as traditional medicines used to treat various diseases in eastern Asian countries, especially China, Japan and Korean. Previous phytochemical studies have revealed that Phellinus fungi produce diverse secondary metabolites, which mainly contain polysaccharides, flavones, coumarins, terpenes, steroids, and styrylpyranones. Pharmacological documents have demonstrated that Phellinus mushrooms and their compounds have a variety of bioactivities, such as anti-tumor, immunomodulation, anti-oxidative and anti-inflammation, anti-diabetes, neuro-protection, and anti-viral effects. This review surveys the literature reporting the isolation, characterization, and bioactivities of secondary metabolites from the fungi of the genus Phellinus, focusing on studies published in the literature up to April 2020. Herein, a total of more than 300 compounds from 13 Phellinus species and their isolation, characterization, chemistry, pharmacological activities, and relevant molecular mechanisms are comprehensively summarized.

Abstract
Phellinus gilvus (Schwein.) Pat, a species of ‘Sanghuang’, has been well-documented for various medicinal uses, but the genome information and active constituents are largely unknown. Here, we sequenced the whole-genome of P. gilvus, identified phenylpropanoids as its key anti-cancer components, and deduced their biosynthesis pathways. A 41.11-Mb genome sequence was assembled and the heatmap created with high-throughput chromosome conformation capture techniques data suggested all bins could be clearly divided into 11 pseudochromosomes. Cellular experiments showed that P. gilvus fruiting body was more effective to inhibit hepatocellular carcinoma cells than mycelia. High resolution electrospray ionization mass spectroscopy (HR-ESI-MS) analysis revealed P. gilvus fruiting body was rich in phenylpropanoids, and several unique phenylpropanoids in Phellinus spp. exhibited potent anti-carcinogenesis activity. Based on genomic, HR-ESI-MS information and differentially expressed genes in transcriptome analysis, we deduced the biosynthesis pathway of four major phenylpropanoids in P. gilvus. Transcriptome analysis revealed the deduced genes expressions were synergistically changed with the production of phenylpropanoids. The optimal candidate genes of phenylpropanoids’ synthesis pathway were screened by molecular docking analysis. Overall, our results provided a high-quality genomic data of P. gilvus and inferred biosynthesis pathways of four phenylpropanoids with potent anti-carcinogenesis activities. These will be a valuable resource for further genetic improvement and effective use of the P. gilvus.

Abstract
Phellinus baumii, also called “Sang Huang” in China, is broadly used as a kind of health food or folk medicine in Asia for its high biological activities, e.g. anti-tumor, anti-oxidation and anti-inflammatory activities. Although some previous studies have indicated that polysaccharides and flavonoids showed the activity of inhibiting tumor cells, the active metabolites of P. baumii needs further research. In our study, a stable P. baumii mutant (A67), generated by ARTP mutagenesis strategy, showed more significantly inhibiting tumor cells and enhancing antioxidant activity. Our further studies found that the increase of polyphenols content, especially hispidin, was an important reason of the biological activity enhancement of A67. According to the results of the integrated metabolome and proteome study, the increase of polyphenol content was caused by upregulation of the phenylpropanoid biosynthesis. This study expanded the understanding of active compounds and metabolic pathway of P. baumii.

RAPID COMMUNICATIONS IN MASS SPECTROMETRY : RCM 2018; 32:221-229. [PMID: 29178526 DOI: 10.1002/rcm.8036] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/25/2017] [Revised: 11/10/2017] [Accepted: 11/12/2017] [Indexed: 06/07/2023]
Abstract
RATIONALE The direct detection of nonpolar and low-polarity solvent extracts of herbal medicine is difficult by conventional electrospray ionization mass spectrometry (ESI-MS). This problem can be solved by solvent-assisted electrospray ionization mass spectrometry (SAESI-MS). With the help of assisted solvents (ESI-friendly solvents) at the tip of the spray needle, compounds (especially the low-polarity compounds) in nonpolar and low-polarity solvent extracts can be ionized directly. METHODS Herbal medicines were ultrasonically extracted with nonpolar or low-polarity solvents, such as petroleum ether. Thereafter, the extracts were analyzed by conventional ESI-MS, atmospheric pressure chemical ionization mass spectrometry (APCI-MS) and SAESI-MS. The mass spectra obtained from these three methods were compared and analyzed. RESULTS Unstable ion signals, and even no ion signals, were observed when the nonpolar and low-polarity solvent extracts were detected directly by conventional ESI-MS. Better specificity, higher sensitivity or cleaner spectra were acquired from SAESI-MS by comparing with the performance of conventional ESI-MS. The ion signals generated by SAESI-MS and APCI-MS were observed in clearly different m/z ranges. A variety of potential compounds were detected in the petroleum ether extracts of Pogostemon cablin and Ligusticum chuanxiong. The relative abundances and signal intensities of the same ion signals from the stems, leaves and decoction pieces of Pogostemon cablin were significantly different by SAESI-MS. CONCLUSIONS As a convenient and efficient method, SAESI-MS can be used to directly detect compounds (especially the low-polarity compounds) in nonpolar or low-polarity solvent extracts of herbal medicines, providing abundant chemical information for pharmacological studies. SAESI-MS allows the simultaneous qualitative analysis of multiple compounds in the same complex samples and is thus particularly suitable for the preliminary screening of compounds in complex samples. SAESI-MS can be used to differentiate the different parts of herbal medicines.
