“…The genus Boesenbergia Kuntze, belonging to the family Zingiberaceae Martinov, is well-known for its herbaceous plants that hold both culinary and medicinal significance. This genus encompasses 99 species (Lam et al 2022), primarily distributed throughout the Indo-Malayan region. The majority of the generic diversity is concentrated in the Malayan archipelago, with India hosting meagrely 11 species at the western extremity of the overall distribution range.…”

A new species of Boesenbergia, B. ashihoi Suparna, Sameer Patil & V.Deepu is described from Lumdiengsai, Meghalaya, India. Boesenbergia ashihoi resembles B. siphonantha (King ex Baker) M.Sabu, Prasanthk. & Škornick. and B. tillandsiodes (Baker) Kuntze in bearing a small globular rhizome, long‐petioled leaves, horn‐like spike and anther connectives without crest, but differs in having elliptic leaves (versus oblong‐lanceolate), bracteoles much shorter than bracts (versus almost equalling bracts), labellum orbicular with orangish throat (versus ovate to obovate or cuneate with reddish or yellowish throat), and corolla tube 9–10 cm long (versus 1–6 cm long). The new species is described and illustrated in detail. A key to species of Boesenbergia in India is provided.

“…The Boesenbergia plants (Zingiberaceae family), which are perennial rhizomatous herbs, have approximately 70 species and are widely distributed in Thailand, Malaysia, Brunei, Indonesia, and the Philippines. About one-third of Boesenbergia plants are indigenous to Borneo [7,8]. Moreover, several biological effects of the extracts derived from Boesenbergia plants have been reported, including antiulcerogenic (B. rotunda) [9,10], wound-healing (B. rotunda) [11], antibacterial (B. rotunda) [12,13], anti-SARS-CoV-2 (B. rotunda) [14], and antioxidant (B. rotunda [15] and B. pulcherrima [16]) properties.…”

Boesenbergia stenophylla-Derived Stenophyllol B Exerts Antiproliferative and Oxidative Stress Responses in Triple-Negative Breast Cancer Cells with Few Side Effects in Normal Cells

Triple-negative breast cancer (TNBC) is insensitive to target therapy for non-TNBC and needs novel drug discovery. Extracts of the traditional herb Boesenbergia plant in Southern Asia exhibit anticancer effects and contain novel bioactive compounds but merely show cytotoxicity. We recently isolated a new compound from B. stenophylla, stenophyllol B (StenB), but the impact and mechanism of its proliferation-modulating function on TNBC cells remain uninvestigated. This study aimed to assess the antiproliferative responses of StenB in TNBC cells and examine the drug safety in normal cells. StenB effectively suppressed the proliferation of TNBC cells rather than normal cells in terms of an ATP assay. This preferential antiproliferative function was alleviated by pretreating inhibitors for oxidative stress (N-acetylcysteine (NAC)) and apoptosis (Z-VAD-FMK). Accordingly, the oxidative-stress-related mechanisms were further assessed. StenB caused subG1 and G2/M accumulation but reduced the G1 phase in TNBC cells, while normal cells remained unchanged between the control and StenB treatments. The apoptosis behavior of TNBC cells was suppressed by StenB, whereas that of normal cells was not suppressed according to an annexin V assay. StenB-modulated apoptosis signaling, such as for caspases 3, 8, and 9, was more significantly activated in TNBC than in normal cells. StenB also caused oxidative stress in TNBC cells but not in normal cells according to a flow cytometry assay monitoring reactive oxygen species, mitochondrial superoxide, and their membrane potential. StenB induced greater DNA damage responses (γH2AX and 8-hydroxy-2-deoxyguanosine) in TNBC than in normal cells. All these StenB responses were alleviated by NAC pretreatment. Collectively, StenB modulated oxidative stress responses, leading to the antiproliferation of TNBC cells with little cytotoxicity in normal cells.

Three new species of Boesenbergia, B. bosuangiisp. nov., B. ganaensissp. nov. and B. gokusingiisp. nov. were discovered in Sabah, Malaysia. Boesenbergia bosuangii is similar to B. stenophylla R.M.Sm. in the narrowly ovate lamina but differs in the shape of the bract and the calyx. Boesenbergia ganaensis is closely allied to B. burttiana R.M.Sm. but differs in the absence of a ligule, the longer petiole, the obtuse leaf base, the acute leaf apex, the bilobed calyx and the anther dehiscing by pores. Finally, B. gokusingii is similar to B. variegata R.M.Sm., by the single leafy shoot but differs in having an unequal, ovate lamina, a cordate leaf base, an acute leaf apex and the anther dehiscing by pores. The three new species are described and illustrated in detail. With the addition of these new species, there are in total 13 species with one variety in Sabah.
