Description: 

Cultivation;

Flowers: 

Flowering season April-December; fruiting from June to February next year.

Distribution: 

Laos, Myanmar, Thailand and Viet Nam (Binh Thuan, Nghe An and Thanh Hoa).

Ecological: 

Lives in evergreen or semi-deciduous secondary forests on low mountains, moist places in limestone and earthen mountains, at an altitude of 10-600 m. 

Chemical constituents and Pharmacology:

(3S,5S)-3,5-diacetoxy-1,7-bis(3,4,5-trimethoxyphenyl) heptane (1), together with the known docosyl trans-ferulate (2), (1S,2S,4S)-p-menthan-1,2,4-triol (3), 5αH-eudesmane-4α,11-diol (4), 5αH-eudesmane-4β,11-diol (5), 4α,10β-dihydroxy-1βH,5αH-guaia-6-ene (guaianediol) (6), (+)-galanolactone (7), (E)-labda-8(17),12(13)-dien-15,16-olide (8), labda-8(17),13(14)-dien-15,16-olide (9), 3,5-dihydroxy-7,4'-dimethoxyflavone (10) and 3,5,3'-trihydroxy-7,4'-dimethoxyflavone (11) were isolated from the rhizomes of Zingiber mekongense. Their structures were determined by spectroscopic methods. The stereochemistry of 1 was proved through chemical conversion. Compounds 1, 4-7 and 9-11 exhibited anti-HIV-1 activities in the anti-syncytium assay using (∆Tat/rev)MC99 virus and 1A2 cell line system, while only compounds 7 and 11 were found active in the HIV-1 reverse transcriptase assay.
