Yao SF, Zhang HB, Cai ZS, Gao H, Wang D, Shang SB. Two new steroidal sapogenins from Rohdea chinensis (synonym Tupistra chinensis) rhizomes and their antifungal activity. JOURNAL OF ASIAN NATURAL PRODUCTS RESEARCH 2022; 24:153-162. [PMID: 33583288 DOI: 10.1080/10286020.2021.1886088] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Accepted: 02/02/2021] [Indexed: 06/12/2023]
Abstract
Two novel acylated steroidal sapogenins, 3β-acetoxy-1α, 2α, 4β, 5α, 7α-pentahydroxy-spirost-25(27)-en-6-one (1) and (25S)-3α-acetoxy-1α, 2β, 4α, 5α, 7α-pentahydroxyspirostan-6-one (2), together with two known steroidal sapogenins (3 and 4), were isolated from Rohdea chinensis rhizomes. Their structures were elucidated by nuclear magnetic resonance (NMR) and mass spectrometry (MS) data. In addition, the antifungal activities of the isolated compounds against Penicillium digitatum and Rhizopus stolonifera were evaluated. Compound 2 significantly inhibited R. stolonifera growth, which was comparable to the positive control (sodium benzoate and carbendazim). Compound 4 showed the highest potency to inhibit P. digitatum growth compared to other compounds.

Abstract
Naturally occurring saponins are a large group of triterpene and steroid glycosides characterized by several biological and pharmacological properties. The Medicago genus represents a valuable source of saponins which have been extensively investigated. This review summarizes the chemical features of saponins from Medicago species and their biological activity, with particular attention to their antimicrobial, insecticidal, allelopathic and cytotoxic effects. Influence of saponins on animal metabolism is also reported.

Abstract
SERF, an NMR pulse sequence for selectively measuring a spin coupling constant without interference from other couplings, was published by the current author almost 25 years ago in 1995. Since then, about 35 modifications and extensions of the original have been published by other groups and applied to many chemical problems. This review discusses these modifications and provides pertinent examples. A comparative and critical evaluation of these developments is given in tabular form. The last part focuses on the chemical results.

Abstract
An approach based on the difference (Δab = δa – δb) between 1H NMR chemical shifts (δa, δb) of the geminal protons of oxymethylene (H2-26) (Δab = <0.2 for 25 R; Δab = >0.5 for 25 S) is proposed for ascertaining 25 R/25 S orientation of the 27-methyl group for (22 R)-spirostane-type steroidal sapogenins and steroidal saponins. These studies suggested the 25 R-orientation of the 27-Me group for the steroidal saponins isolated by Temraz et al. from Tribulus alatus.

Abstract
Most chemical and biological studies about garlic have been conducted using organosulfur compounds. However, a variety of steroid saponins from garlic and related Allium species are being increasingly recognized for their importance in biological processes. This report demonstrates the isolation and structure determination of steroid saponins from garlic and aged garlic extract (AGE). In addition, the in vitro antifungal antitumor cytotoxicity and blood coagulability effects of steroid saponins from garlic and related Allium species are provided. Animal studies on the cholesterol-lowering effects of the saponin fractions from garlic are also summarized.
