Ovary narrowly oblong, to 7.5 mm, pilose. Stigma lobes longer than style. Berry subfusiform, 1.2-1.5 × ca. 0.6 cm; beak ca. 2.5 mm. Fl. and fr. Apr-Sep.
Distribution: It is found in Cambodia, India, Indonesia, Japan, Laos, Myanmar, Pakistan, Papua New Guinea, Philippines, Thailand, Vietnam. In Vietnam: Lao Cai, Hà Tây, Hoà Bình, Hải Dương, Nghệ An, Quảng Trị, Thừa Thiên Huế, Kon Tum
Ecological: Plants grow naturally on grassy hills, scrublands, along streams and rock niches.
Chemistry:
- Phenolic glucosides: orchiosides A and B
- Cycloartane glycosides from the rhizomes: 3beta-[(beta-D-glucopyranosyl)oxy]-12R,16beta-dihydroxy-9,19-cyclol- anostan-24-one; 12alpha,16beta- dihydroxy-3beta-[(O-R-L-rhamnopyranosyl-(1->2)-beta-D-glucopyrano- syl)oxy]-9,19-cyclolanostan-24-one; 3beta-[(O-beta-D-glucopyranosyl-(1->2)-beta-D-glucopy- ranosyl)oxy]-12alpha,16beta-dihydroxy-9,19-cyclolanostan-24-one.; 3beta-[(O-beta-D-glucopyranosyl-(1->6)-beta- D-glucopyranosyl)oxy]-12alpha,16beta-dihydroxy-9,19-cyclolanostan-24- one.; 3alpha-[(O-beta-D-glucopyranosyl-(1->3)-alpha- D-glucopyranosyl)oxy]-1-2alpha,16beta-dihydroxy-9,19-cyclolanostan-24-one.; 3beta-[(O-beta-D-glucopyranosyl- (1->3)-O-beta-D-glucopyranosyl-(1->2)-beta-D-glucopyranosyl)oxy]- 12alpha,16beta-dihydroxy-9,19-cyclolanostan-24-one
Pharmacology: Compounds cycloartane glycosides from the rhizomes showed cytotoxic activity against HL-60 cells with IC50 values of 9.0 and 1.8 μM, respectively. The cancer cell growth inhibition of 1a was also examined using a panel of 39 human cancer cell lines in the Japanese Foundation for Cancer Research.
Uses:
- In Viet Nam: Kidney tonic, high blood pressure, numbness, diarrhea, arousal (Drinking roots).
- Its rhizomes have been used in traditional medicines in tonics and for the treatment of asthma and hyperpiesia.
